UIButton displaying view but not toggling to pause button
|
<p>I Have a UIButton and it has multiple actions associated with it </p>
<ol>
<li>To play audio file</li>
<li>Toggle between play pause button</li>
<li>Display views</li>
</ol>
<p>If i comment out the displayViewAction: it is working fine (i.e playing audio file and also toggling to pause button). But if I use the displayViewAction: method it is playing audio file displaying view but before displaying the view it should immediately toggle the state of the pause button, but it is not.</p>
<p>Code bellow for reference:</p>
<p>Code for UIButton:</p>
<pre><code>UIButton *playpauseButton = [UIButton buttonWithType:UIButtonTypeCustom];
[playpauseButton addTarget:self action:@selector(playpauseAction:) forControlEvents:UIControlEventTouchUpInside];
[playpauseButton addTarget:self action:@selector(displayviewsAction:) forControlEvents:UIControlEventTouchUpInside];
playpauseButton.frame = CGRectMake(0, 0, 50, 50);
[playpauseButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];
[playpauseButton setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateSelected];
UIBarButtonItem *playpause = [[UIBarButtonItem alloc] initWithCustomView:playpauseButton];
</code></pre>
<p>Code for Playpause button:</p>
<pre><code>-(void)playpauseAction:(id)sender
{
if ([audioPlayer isPlaying]){
[sender setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];
[audioPlayer pause];
}
else {
[sender setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];
[audioPlayer play];
}
}
</code></pre>
<p>Code for display view action:</p>
<pre><code>- (void)displayviewsAction:(id)sender
{
self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease];
[self.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
PageOneViewController *viewController = [[[PageOneViewController alloc] init]autorelease];
[self.view addSubview:viewController.view];
}
</code></pre>
<p>Can anyone please advise how I can make it work this way?</p>

How to rotate my view-based app to the new interface orientation?
|
<p>I have a simple view-based app from that template. It has nothing else in there, only one UIButton.</p>
<p>When the device rotates, I want that button to be re-layoutet in such a way that it fits the width of the screen automatically. It has a margin of 20 points left and right, which should always remain the same.</p>

Android: OnKeyListener camera button?
|
<p>I'm currently making a game for Android in which I'd like to be able to shoot using the camera button (Or a different hardware button I don't mind, just tapping the screen would be rubbish).</p>
<p>In my view I have:</p>
<pre><code>public class GameFrame extends SurfaceView implements SurfaceHolder.Callback, OnKeyListener{
public GameFrame(Context context){
...
setOnKeyListener(this);
...
}
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getAction() == KeyEvent.ACTION_DOWN)
{
shoot();
return true;
}
return false;
}
}
</code></pre>
<p>This however doesn't do anything, shoot() is never called even when I'm furiously hitting all the keys on my phone!
Is there something obvious I've missed out, or have I done it completely wrong?</p>
<p>Cheers</p>

Managing screen flow
|
<p>To keep it simple I have 3 screens. A, B and C.
You can access Screen B or C from screen A.
You can access Screen C from screen B
You can access Screen B from screen C</p>
<p>Data from screen A is passed to B and C</p>
<p>What I am looking to do is create a button on screen B and C and where ever they are takes it back to screen A. I do not want to start a new activity of A as it requires the data it created</p>
<p>Also is there a way to overrule what the back button on the phone does. ie if on screen C it goes back to A even is the user clicked B and then C?</p>
<p>Thanks for your time</p>

Java- How to write a lobby game server
|
<p>So I'm writing a Chess matchmaking system based on a Lobby view with gaming rooms, general chat etc. So far I have a working prototype but I have big doubts regarding some things I did with the server. Writing a gaming lobby server is a new programming experience to me and so I don't have a clear nor precise programming model for it. I also couldn't find a paper that describes how it should work. I ordered "Java Network Programming 3rd edition" from Amazon and still waiting for shipment, hopefully I'll find some useful examples/information in this book.</p>
<p>Meanwhile, I'd like to gather your opinions and see how you would handle some things so I can learn how to write a server correctly. Here are a few questions off the top of my head: (may be more will come)</p>
<p>First, let's define what a server does. It's primary functionality is to hold TCP connections with clients, listen to the events they generate and dispatch them to the other players. But is there more to it than that?</p>
<p>Should I use one thread per client? If so, 300 clients = 300 threads. Isn't that too much? What hardware is needed to support that? And how much bandwidth does a lobby consume then approx?</p>
<p>What kind of data structure should be used to hold the clients' sockets? How do you protect it from concurrent modification (eg. a player enters or exists the lobby) when iterating through it to dispatch an event without hurting throughput? Is ConcurrentHashMap the correct answer here, or are there some techniques I should know?</p>
<p>When a user enters the lobby, what mechanism would you use to transfer the state of the lobby to him? And while this is happening, where do the other events bubble up?</p>
<p>Input is greatly appreciated. Thanks!</p>

Receding and Protruding menu tabs Jquery
|
<p>Sorry if this is a silly question but I have been on web design for 2 weeks and I am trying to make some menu tabs. Specificity ones that protrude when you mouseover and recede back to start position when mouseleave. I have made some code but it seems to act strangely.
When I mouse over its fine and the tab comes down 10px but when I leave the second time on any tab it recedes 10px then another 10px and it adds up each time incrementally, 20, 30, 40 etc.</p>
<p>I have tried popping in a stop even propergation but I am still learning. If its messy let me know.</p>
<p>Here is the code.</p>
<pre><code>$(document).ready(function(){
$('.buttons').mouseover(function(){
$(this).animate({top: '+=10'}, 200, function() {
$(this).mouseleave(function(){
$(this).animate({top: '+=-10'}, 200, function() {
});
});
});
});

Android DB List Adapters: multiple columns, aligned?
|
<p>Ok I can't find a sample anywhere.</p>
<p>I've done the notepad tutorial on Google's Android site, but I would like to know how to add more fields to the list, in columns. At the moment I can add the columns no problem, but they're not aligned like you would a normal table on the layout:</p>
<pre><code>john smith
heinrich cilliers
will peck
</code></pre>
<p>I would like the first names and last names aligned proportionately, as you would in an html table.</p>
<p>It works if I use a constant value for the layout_width parameter (100dip etc), but I would prefer to use a relative percentage. However it's becoming clear that each row is on it's own, and does not know how to alighn itself with the row above.</p>
<p>Any pointers?</p>
<p>UPDATE: I've reached an experienced Android developer which advised me to use WeightSum, which brings me closer, but vertical alignment is stil not happening:</p>

Carousel as button not working unless slide is in first position
|
<p>I'm creating a set of controls to combine product color and patterns into one image. This is accomplished by changing the values to two drop downs and clicking on images in two bxslider carousels. Everything works until you click on a carousel in the second postion after one full rotation (left: -200px). If this one is clicked, nothing happens. Here's my code for the carousel's click function and a link to a live example. You have to click on at least one picture in each carousel for it to start.</p>
<pre><code>$(document).ready(function(){
$('ul.carousel_front li img').click(function() {
if($(this).hasClass('inactive_front'))
{
$(this).addClass('inactive_front').removeClass('active_front');
}
else
{
$("ul.carousel_front li img").removeClass("active_front");
$(this).addClass("active_front");
}
html = '<img src="images/' + $('#front_finish').val() + '_' + $('.active_front').attr("id") + '_' + $('#back_finish').val() + '_' + $('.active_back').attr("id") + '.jpg">';
$("#main-image").html(html);
}); });

prevent click happen in a children element
|
<p>I set a event to a <code>wrapper div</code>, but inside this <code>div</code>, i have some <code>buttons</code>, how can i <strong>prevent</strong> this <code>wrapper</code> event happen in the <code>buttons</code> ?</p>
<p><strong>html</strong>:</p>
<pre><code><div class="wrapper-alert"> <!-- click here will pop-up -->
<div class="somethingElse"> <!-- click here will pop-up -->
Some text
</div>
<div class="this-is-my-action">
<button class="inside-alert">Inside</button> <!-- click here will NOT pop-up-->
</div>
<div class="somethingElseTo"> <!-- click here will pop-up -->
Some text
</div>
</div>
</code></pre>
<p>i made a <a href="http://jsfiddle.net/NxnW2/37/" rel="nofollow"><strong>jsfiddle</strong></a> to be more clear.</p>
<p>so, basicly, if i click in the <code>wrapper-alert</code> some message will pop-up, but if i click in the <code>button</code> other thing will happen, <strong>the problem is that the buttons are children from wrapper, so 2 events will fire at once.</strong></p>
<p>i have try something with <code>if (e.target !== this) return;</code> but works only with one <code>children</code>, or some basic structure.</p>

how to resume/suspend a pthread in iphone os?
|
<p>Now i face a problem in my porting job, when i need to implement a thread class that will work in not only wince, symbian ,but also unix-like system, like iphone.</p>
<p>I own a suspend/resume interface to implement, anything is ok in wince/symbian except iphone, i use the posix pthread to finish my job, but i search the whole docsets for a resume/suspend-like interface. Things seem to be difficult, pthread in iphone own a <strong>*pthread_create_suspended_np*</strong> that can create a thread in a suspend mode. Now how can i resume or suspend a thread after the thread has run to its stuff in anytime.</p>
<p>BTW, i search Google for some help, it seems that someone else also have this problem .
Some guys suggest use the <strong><em>SIGHUP</em></strong> signal, but this will suspend the whole process, that's absolutely not ok .</p>
<p>Many thanks if you guys can tell me some solutions for this problem.</p>

<p>Hello</p>
<p>we have dictionary like this:</p>
<pre><code>data = {'raw':'lores ipsum', 'code': 500}
</code></pre>
<p>how to convert this dict to strings? result must be like this:</p>
<pre><code>print raw
print code
#output is
# lores ipsum
# 500
</code></pre>
<p><strong>EDIT:</strong>
OK, so what I want is to have raw and code variable available.. one more example</p>
<pre><code>data = {'raw':'lores ipsum', 'code': 500}
var1 = code
var2 = raw
</code></pre>
<p>it's becomes difficult to make tons of string operations with variable, which is dict, which is in class method...
so it's endups with this: self.data['raw'][0] , it's killing me to write this everytime so to make "raw" variable is more comfortable... (imagine join and format operation with using this on every line!!!) anyway this vars will be available only in this method, so there's no side-effects for this solution...</p>
<p><strong>EDIT: deleted, nobody understands what I want</strong></p>

Multiple values for each tree record

<p>I have constructed a tree to hold a single string(data) for each record. How can I make it hold multiple strings for each record?</p>
<pre><code>void BinarySearchTree::insert(string d)

tree_node* t = new tree_node;
tree_node* parent;
t->data = d;
t->left = NULL;
t->right = NULL;
parent = NULL;
// is this a new tree?

else
{
//Note: ALL insertions are as leaf nodes
tree_node* curr;
curr = root;
// Find the Node's parent
while(curr)
{

if(t->data < parent->data)
parent->left = t;

Offer access to a private page without login
|
<p>So I've been struggling with a nice and easy way to allow users to access a private page without asking them to fill out a login/password form. </p>
<p>What I'm thinking about using right now is for each private page I generate a uniqueid (using php uniqid function) and then send the URI to the user. He would access his private page as "www.mywebsite.com/private_page/13ffa2c4a". I think it's relatively safe and user friendly, without asking too much of information. I thought maybe when the user access this page it would ask for it's e-mail just to be sure, but the best would be nothing at all.</p>
<p>Is this really safe? I mean not internet banking safe, but enough for a simple access? Do you think there's a better solution? Thanks. :)</p>

Cycling through an array of form elements
|
<p>I am returning form elements into a form from ajax. I can count the number of elements returned, but I don't know how to cycle through them. I need to be able to get the value of each element returned.</p>
<p>I am pretty sure this is a basic javascript thing that I just don't know. The problem only looks more complicated with the Ajax.</p>
<p>My code looks like this:</p>
<pre><code> // The view page
<html>
<head>
<script language="javascript">
function calculateAlphaTotals(){
var length = document.myForm["alpha[]"].length;
alert( length ); // correctly outputs 3
for( var i = 0; i < length; i++ ){
try{
alert( document.myForm["alpha[]"].value ); // HTML ObjectCollection
alert( document.myForm["alpha["+i+"]"].value ); // Object Required
} catch( error ) { }
}
}
</script>
</head>
<body>
<form name="myForm" id="myFormId" method="post">
<div id="ajaxOutputId"></div>
</form>
</body>
</html>
// The Ajax page:
<input name="alpha[]" onchange="calculateAlphaTotals()" />
<input name="alpha[]" onchange="calculateAlphaTotals()" />
<input name="alpha[]" onchange="calculateAlphaTotals()" />

jQuery: Any better way to write this? Multiple each() loops

$j(this).children().find(".resultList").each(function(i){
if($j(this).height() > currentTallest){

$j(this).children().find(".resultList").each(function(i){

$j(this).css({'height': currentTallest + 5});
}
$j(this).css({'min-height': currentTallest});

<p>Updates:
After taking all the constructive comments into consideration, I have come up with the following which seems to work as desired:</p>
<pre><code>$j.fn.equalHeights = function(px) {
$j(this).each(function(){
var currentTallest = 0;
var results;
if($j(".eachLateDeal").length){
results = $j(".resultList", ".eachLateDeal");
}else{
results = $j(this).children();
}
$j.each(results, function(){
if($j(this).height() > currentTallest){
currentTallest = $j(this).height();
}
});
var cssProp = {};
if (!$j.support.minHeight){
cssProp["height"] = currentTallest + 5;
}else{
cssProp["min-height"] = currentTallest;
}
results.css(cssProp);
});

PHP: __set function behaviour different each time
|
<p>This manages to create a new property on the object. But, can someone explain, with supporting links, why <code>setAttrib</code> behaves in two different ways? Why doesn't it cause a... wait for it... stack overflow!!??</p>
<pre><code>class Test
{
public function setAttrib( $key, $value ) {
echo "setAttrib\n";
// first time: calls $this->__set($key, $value)
// second time: just sets a public property (but, when exactly was it created?)
$this->$key = $value;
}
public function __set( $key, $value ) {
echo "__set\n";
$this->setAttrib($key, $value);
}
}
$test = new Test();
$test->setAttrib('hey', 'It works');
var_dump($test);
</code></pre>
<p>produces...</p>
<pre><code>setAttrib
__set
setAttrib
object(Test)#1 (1) {
["hey"]=>
string(8) "It works"

Using Unsigned Primitive Types
|
<p>Most of time we represent concepts which can never be less than 0. For example to declare length, we write:</p>
<pre><code>int length;
</code></pre>
<p>The name expresses its purpose well but you can assign negative values to it. It seems that for some situations, you can represent your intent more clearly by writing it this way instead:</p>
<pre><code>uint length;
</code></pre>
<p>Some disadvantages that I can think of:</p>
<ul>
<li>unsigned types (uint, ulong, ushort) are not CLS compliant so you can't use it with other languages that don't support this</li>
<li>.Net classes use signed types most of the time so you have to cast</li>
</ul>
<p>Thoughts?</p>

Function accessing itself when name is overwritten by argument
|
<p>Normally, a function can access itself like this:</p>
<pre><code>(function f() {
console.log(f); // Prints the function definition
}());
</code></pre>
<p>However, when the function <code>f</code> has an argument also called <code>f</code>, the argument takes precedence:</p>
<pre><code>(function f(f) {
console.log(f); // Prints 1
}(1));
</code></pre>
<p>In the second example, how can I access the function when one of the arguments has the same name as the function?</p>
<p>[Also, where can I find the documentation saying that the argument should take precedence over the function name?]</p>

Problem in implementing my own switch class
|
<p>I am trying to implement a custom switch case just for fun..</p>
<p>The approach is that I have created a class that inherits a dictionary object</p>
<pre><code>public class MySwitch<T> : Dictionary<string, Func<T>>
{
public T Execute(string key)
{
if (this.ContainsKey(key)) return this[key]();
else return default(T);
}
}
</code></pre>
<p>And I am using as under</p>
<pre><code> new MySwitch<int>
{
{ "case 1", ()=> MessageBox.Show("From1") },
{ "case 2..10", ()=>MessageBox.Show("From 2 to 10") },
}.Execute("case 2..10");
</code></pre>
<p>But if I specify <strong>"case 2"</strong> it gives a default value as the key is not in the dictionary.</p>
<p>The whole purpose of making <strong>"case 2..10 "</strong> is that if the user enters anything between <strong>case 2 to case 10</strong>, it will execute the same value.</p>
<p>Could anyone please help me in solving this?</p>
<p>Thanks</p>

Why does HttpContext.Response.Cookies["foo"] add a cookie?
|
<p>I have just spent half a day tracking down a bug due to the following behaviour: -</p>
<p>Imagine that there is <strong>not</strong> a cookie called "foo" in either the Http request's or response's cookie collections. The following code returns null</p>
<pre><code>A) HttpContext.Current.Request.Cookies["foo"]
</code></pre>
<p>The following code creates a new cookie called "foo" (with path="/" and blank value), adds it to the response's cookie collection and returns that</p>
<pre><code>B) HttpContext.Current.Response.Cookies["foo"]
</code></pre>
<p>So (B) has the side effect that any pre-existing cookie called "foo" is overwritten on the client's browser.</p>
<p>This is not a bug. Someone actually coded this deliberately. Here is the disassembly of the Get method (the Item[string name] indexer delegates to this method.</p>
<pre><code> public HttpCookie Get(String name) {
HttpCookie cookie = (HttpCookie)BaseGet(name);
if (cookie == null && _response != null) {
// response cookies are created on demand
cookie = new HttpCookie(name);
AddCookie(cookie, true);
_response.OnCookieAdd(cookie);
}
return cookie;
}
</code></pre>
<p>Obviously the MSDN docs do not mention this behaviour (although some users have added comments at the bottom of the docs that describe this behaviour).</p>
<p>My question is can someone explain to me the rational why the <code>HttpCookieCollection</code> class has this behaviour.</p>

How to "discard" form changes?
|
<p><strong>Setup:</strong></p>
<p>I have a form and a "Submit" button. Ideally the user should fill out the form, click "Submit" and then leave the tab. If he tries to leave the tab without saving the changes, I need to alert him with 3 options:</p>
<ol>
<li>Save</li>
<li>Discard: discard the form data changes, and leave the tab, as if the data was never modified. If user comes back to the same tab, he should see the "unmodified" data.</li>
<li>Cancel: Just dismiss the dialog box, keep the user on the same tab. User can either modify the data further, click save, etc.</li>
</ol>
<p><strong>Problem:</strong></p>
<p>Implementing Save and Cancel is easy. The issue is with "Discard". If the user clicks "Discard", the form data should get restored to what it was before modification.</p>
<p>Is there any way to do this? If I haven't explained issue properly, please let me know. </p>

C# Use a class that implements an interface without adding a reference to the assembly that defines the interface
|
<p>I have 3 assemblies written in C#, namely A.exe, B.dll, C.dll</p>
<ul>
<li>C.dll defines a public interface IfaceC.</li>
<li>A.exe defines a public class ClassA : IfaceC</li>
<li>B.dll uses ClassA but does not make explicit use of IfaceC</li>
</ul>
<p>My question: is it possible to compile B <strong>without</strong> referencing C.dll ? I do not use it and I want to prevent a developer from using it (i.e. typing "IfaceC" in the B's code accidentally). However A.exe still needs it.</p>

<p>Given my archi, A can reference C but not B, C cannot reference nor A neither B, B can reference A <strong>but not (if possible) C</strong></p>

php trim function trims extra Less-than/Greater-than signs
|
<p>I have a question about the PHP trim function.
Consider the following:</p>
<pre><code>$x= '<p>blah</p>';
$x= trim(trim($x, '<p>'), '</p>');
echo htmlentities($x) . "<br />";
This works as expected and prints blah
</code></pre>
<p>.</p>
<pre><code>$x= '<p><b>blah</b></p>';
$x= trim(trim($x, '<p>'), '</p>');
echo htmlentities($x) . "<br />";
This prints b>blah</b
</code></pre>
<p>I'm not looking for other ways around this.<br />
I do wonder why the trim function shows this behavior (stripping the extra Less-than/Greater-than sign).</p>
<p>Thanks in advance.</p>

Location Manager not obtaining GPS location properly
|
<p>i am supposed to obtain the current location of the user , for this i have implemented the following code:</p>
<pre><code>lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
ll = new mylocationlistener();
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, ll);
</code></pre>
<p>Here is my LocationListener class:</p>
<pre><code> private class mylocationlistener implements LocationListener {
@Override
public void onLocationChanged(Location location) {
if (location != null) {
Log.d("LOCATION CHANGED", location.getLatitude() + "");
Log.d("LOCATION CHANGED", location.getLongitude() + "");
lat = location.getLatitude();
lng = location.getLongitude();
Toast.makeText(NearActivity.this, "lng=" + lng + " lat=" + lat,
Toast.LENGTH_SHORT);
showProgress();
}
}
</code></pre>
<p>The above code is not setting the variables lat and lng which are global variables. Why is the GPS not able to provide the cordinates? </p>
<p>Thank you in advance.</p>

return "True"
else:
return "False"

POST not working inside click function

<p>I have this working perfectly:</p>
<pre><code>$.post("check_i.php", {value: '<?php echo md5($_SERVER['REMOTE_ADDR']);?>'},
function(result) {
if(result == 'true') {
alert('true');
} else {
$.post("update_pop_count.php", {site: '<?php echo $site;?>'});
}
});
</code></pre>
<p>However when I try to put this inside a click link function, in firebug I can see that check_i.php takes forever, and update pop count is never called (i can see in the database that the count is not updated)</p>
<p>This is my code with the click function:</p>
<pre><code>$("a").click(function() {
$.post("stats_include/ajax/check_i.php", {value: '<?php echo md5($_SERVER['REMOTE_ADDR']);?>'},
function(result) {
if(result == 'true') {
alert('true');
} else {
$.post("stats_include/ajax/update_pop_count.php", {site: '<?php echo $site;?>'});
}
});
});
</code></pre>
<p>This is all inside a document.ready function. Any ideas?</p>

Closures in C++
|
<p>I've found myself in a strange place, mentally. In a C++ project, I long for closures.</p>
<p>Background. There's a Document-type class with a public Render method which spawns a deep call tree. There's some transient state that only makes sense during rendering. Right now it resides in the class like regular member variables. However, this is not satisfactory on some levels - this data only makes sense during a Render call, why store it all the time? Passing it around in arguments would be ugly - there are around 15 variables there. Passing around a structure would add a lot of "RenderState->..." in the lower-level methods.</p>
<p>So what do I want? I want the world, like we all do. Specifically, a set of variables that are:</p>
<ul>
<li>available to some methods in a class (not all of them)</li>
<li>accessible by name alone (no pState->... stuff - so that refactoring is easy)</li>
<li>not copied around on every method call</li>
<li>only live during a method call and up its call tree (assuming trees grow up)</li>
<li>live on a stack</li>
</ul>
<p>I know I can have some of those properties with C++ - but not all of them. Tell me I'm not turning weird.</p>
<p>Heck, in Pascal, of all places, nested functions give you all that...</p>
<p><strong>So what is a good workaround to emulate closures in C++, getting as many of the above benefits as possible?</strong></p>

Most efficient method to use position to open a .java
|
<p>Sorry for the formating errors - How do you use position once you have it (or another variable for that matter) to activate a file or other task? For example I want to use position 1 to open screen1.java and position 2 to open screen2.java. I could use if/else statements but can I do it in one line rather than many? If I had 100 different screens then an if then statement would be silly. Here is what I have as an (incorrect) example. Can you help me correct it? </p>
<pre><code>public void onItemClick(AdapterView<?> parent, View v,
int position, long id){
//opens relevant game window
Intent intent = new Intent(context, "game"+(position)+"mainscreen"+".class");
startActivity(intent);
}
});
}
</code></pre>

<B> instead of using </B> game1mainscreen.class <B> I want to use something like </B> "game"+(position)+"mainscreen"+".class"</p>

So confused about why vars work sometimes with or without var?

<p>I am really confused as to why sometimes vars will not work when "var" is declared in front of them when used in a namespaced object. Isn't adding "var" in front of every variable the correct thing to do to keep it outside the global namespace?</p>
<p>Or would creating any var without declaring "var" first in my namespaced object, ensure of this, so I don't eed to worry about "var"?</p>
<p>Here's an example of my code:</p>
<pre><code>MYNAME.DoStuff = {
initialize: function() {
var var1 = 'name'; //1
var2 = 'name'; //2
this.var3 = 'name'; //3
var $var4 = $('#' + name); //4
$var5 = $('#' + name); //5
this.$var6 = $('#' + name); //6
},
linkStuff: function() {
// then use the vars from the init above in here
}
}
MYNAME.DoStuff.initialize();
</code></pre>
