Replacing a number in a string with jquery
|
<p>I have a string which has a number in it that I would like to replace with another number.</p>
<p>ie</p>
<pre><code><a href="" id="my_link">blah blah 32 blah blah</a>
</code></pre>
<p>I know there is only going to be 1 number in this string.</p>
<p>I can get this far:</p>
<pre><code>var my_string = $('a#my_link').text();
</code></pre>
<p>But basically I don't know how to then perform a search on my_string for a numeral and replace that number with something else.</p>
<p>Is that possible with jQuery?</p>
<p>Thanks for any ideas.</p>

<p>Is it possible to have top layer that the user can interact ( my relative layout) with transparent background </p>
<p>Then a bottom layer thats a background image thats scrolling. Thats outside of the control of the user. For example a scrolling image of space. Thats continually scrolling. </p>

Cross-thread operation not valid: Asynchronous delegates error
|
<p>I've been trying to learn delegates.I just created a button,label and checkbox. If I click checkbox, the time format changes. If i click the button , i print the date accordingly. However when trying to use asynchromous delegate i.e., to use another thread, i am stuck with an error</p>
<pre><code> public delegate void AsyncDelegate(bool seconds);
public partial class Form1 : Form
{
AsyncDelegate ad;
TimeZ t = new TimeZ();
public Form1()
{
InitializeComponent();
}
private void btn_async_Click(object sender, EventArgs e)
{
ad = new AsyncDelegate(t.GetTime);
AsyncCallback acb = new AsyncCallback(CB);
if (chk_sec.Checked)
{
ad.BeginInvoke(true, acb, null);
}
else
ad.BeginInvoke(false, acb, null);
}
public void CB(IAsyncResult ar)
{
t.Tim = ar.ToString();
ad.EndInvoke(ar);
lbl_time.Text = t.Tim;
}
</code></pre>
<p>and in another class library i get Timez used above. I add a reference of it in the project </p>
<pre><code> public class TimeZ
{
private string tim;
public string Tim
{
get
{
return tim;
}
set
{
tim = value;
}
}
public string GetTime(bool seconds)
{
if (seconds)
{
return DateTime.Now.ToLongTimeString();
}
else
return DateTime.Now.ToShortTimeString();
}
}
</code></pre>
<p>However i get this error when i run the program:</p>
<pre><code> Cross-thread operation not valid: Control 'lbl_time' accessed from a thread other than
the thread it was created on.
</code></pre>
<p>Can u help me out on how to solve this?</p>

Javascript beginner: how to replace a href text if it matches a specified string?
|
<p>When someone posts a link to another page on my website, I'd like to shorten the a href text from something like: <code>http://mywebsite.com/posts/8</code> to <code>/posts/8</code> or <code>http://mywebsite.com/tags/8</code> to <code>/tags/8</code>. Since I'm learning javascript I don't want to depend on a library like prototype or jquery. Is it recommended to use javascript's <code>replace</code> method?</p>
<p>I found w3schools' page <a href="http://www.w3schools.com/jsref/jsref_replace.asp" rel="nofollow">here</a> but my code was replacing all instances of the string, not just the href text.</p>
<p>Here's what I have so far:</p>
<pre><code><script type="text/javascript" charset="utf-8">
var str="http://www.mywebsite.com";
document.write(str.replace("http://www.", ""));

How are lambda expressions bound to a class?

f = lambda x,y: (x + y)
g = [lambda x,y: (x + y)]
a = A()
#a.f bound
print a.f
<bound method A.<lambda> of <__main__.A object at 0xb743350c>>
#a.g[0] not bound
print a.g[0]
<function <lambda> at 0xb742d294>

jquery variable scope problem

<p>I have a chat class with two methods: updateChat and sendChat.</p>
<pre><code>//chat.js
var state;

function Chat (theRoom) {
this.update = updateChat;
this.send = sendChat;
this.room = theRoom;
}
function updateChat(){
alert('ROOM: '+this.room);

state = data.state;
}
});
}

//send the message

updateChat();

$.ajax({

'function': 'send',
'message': message,
'nickname': nickname,

dataType: "json",
success: function(data){
alert('C'+state); //wrong!: 2 //it should be 20!
//XXX
updateChat();
alert('D'+state); //21
},
});
}
</code></pre>
<p>The constructor of the chat object:</p>
<pre><code>var chat = new Chat(4); //4 = the number of the chat room
chat.send('test', 'tester');
</code></pre>
<p>My problem are the method calls at the locations marked with XXX.
In the updateChat() method, this.room is undefined if I call the updateChat methods like that.
But I need to pass the room number to get the right state (state is simply the number of lines in the chat room's text file).</p>
<p>I think it's a problem with variable scope or with the methods not being called in the context of the object.</p>

java: file read, modify outside, then read again, modification not seen

<p>I have set of files which will be served by a servlet based on a parameter. The servlet opens stream to required file, reads, writes to http response and closes the stream. Now this file can be modified manually and saved. Then next time a request comes for this file, servlet opens a stream to this file, writes it to the response, but I see the content is not the modified one, its the old one. </p>
<p>If I restart tomcat, servlet responds with modified content. Can it be made to read the modified content without restart?</p>
<p>Its not tomcat caching, the string read from file reader itself is unchanged.</p>

Video manipulation using ffmpeg library
|
<p>I need a proper documentation and explanation of the ffmpeg library files that we can use to do programming so as to make a video editor that is capable of adding effects in video and merging 2 different video files.I want to make the editor for android,although i got the android specific ffmpeg files from <a href="http://bambuser.com/opensource" rel="nofollow">http://bambuser.com/opensource</a> but i am unable to utilize them for my purpose.
I tried a simple c program in devC++ using the header files like avcodec.h avformat.h given in ffmpeg but getting linker error for function like av_register_all,av_open_input_file.</p>

Put a string into an array
|
<p>I have a string that contains this:</p>
<p><code>array(a=1, b=2, c=array(ca=23, cb=45),d=array(da=342, db=array(dba=3154, dbb=8746), dc=765),e=8)</code></p>
<p>Now, I need to create an array from the contents of this string. I tried it this way:</p>
<pre><code>$arrValues = array();
$arrValues = $strVar;
var_dump($arrValues);
</code></pre>
<p>But of course, as was to be expected, this just gives you an array with 1 item of type string, and the whole shebang in it.</p>
<p>Any tips?</p>

if AutoFlush slowdown system, bad for HDD or something like that when used intensive?
|
<p>I write a lot of logs every day (millions of strings per day, up to 1 Gb of logs). I'm interested if when I set <code>AutoFlush</code> I significantly slow-down computer or "damaging" HDD (SaS 15000 if this is important)? Will HDD do some expensive extra operations every time new line is wrote (like opening file, modifing closing etc. etc.)</p>
<p>Well likely I just should not use <code>AutoFlush</code> but sometimes I want to use it to troubleshoot other problems.</p>

Scanner stdin = new Scanner(new BufferedInputStream(System.in));
while (stdin.hasNext()) {
System.out.println(stdin.nextInt() + " and the next " + stdin.nextInt());
}

Firefox 4 JS fails to send ~6th AJAX request while other browsers work as expected
|
<p>I'm using jquery to post a form back to the server and it works very reliably on all browsers except FF4 on an older Windows XP setup. It reaches the point where the XHR should have been sent, but I never see the request in the server log.</p>
<p>The machine isn't mine, but is one of my Beta Testers. It's been a consistent problem, but I'm not sure how to debug it. He isn't a web developer, just a friend of a friend that happened to be willing to test a game for us. If he restarts FF, it works about 6 more times and then it fails.</p>
<p>It's a facebook app, and there are other XHRs that Facebook is doing, so the 6th request is in my app. My app is NOT a single page app, but uses 2 XHRs within this one page, one right after page load, and one about 4 minutes later. I'm using setTimeout a bit, but otherwise, nothing else other than trapping keystrokes.</p>
<p>This same code works on a old G4 Mac running Safari 3.0 just fine, without ANY issues for hours at a time.</p>
<p>How do you troubleshoot something like this. Not sure I want to try to get into a remote Firebug session....</p>

jquery context menu plugin - Where is the right click event type?
|
<p>I was studying the code for the plugin below and wondering where and when does it tie the "Right Click" event. All it does is </p>
<p>Plugin reference link : <a href="http://www.javascripttoolbox.com/lib/contextmenu/" rel="nofollow">http://www.javascripttoolbox.com/lib/contextmenu/</a></p>
<p><code>$(this).bind('contextmenu',function(e){cmenu.show(this,e);return false;});</code></p>
<p>and "contextmenu" is a custom jquery event type.</p>
<p>Can someone please explain how all this works</p>
<p>I did check there are click events but those are tied to the menu items and not the element to which the menu is tied.</p>
<p>Thanks</p>
<p>Answer: "contextmenu" is not a custom event type. It is actually another name (mapping etc) for 'right click'</p>

How to show 2 Maps in 1 application at same time using Fragments
|
<p>My problem is I have to run 2 different maps at the same time in same application. Both maps will be visible at same time. I am working on Android 3.2 and using Fragments.</p>
<p>I know "Only one MapActivity is supported per process. Multiple MapActivities running simultaneously are likely to interfere in unexpected and undesired ways." I also checked discussions of running activity in different process with android:process tag. <a href="http://code.google.com/p/android/issues/detail?id=3756#c7" rel="nofollow">http://code.google.com/p/android/issues/detail?id=3756#c7</a></p>
<p>Currently, I am creating an Activity with two fragments and each fragment contains a TabHost. Each TabHost contains a map activity.
</p>
<p>Though I have specified process of each MapActivity but I still get RecyclingMapObject error in Logcat and same map object is reused. Kindly suggest if we can any workaround so that 2 Maps can be displayed at the same time.</p>
<p>Sample source code used from <a href="https://github.com/inazaruk/examples/tree/master/MapFragmentExample" rel="nofollow">https://github.com/inazaruk/examples/tree/master/MapFragmentExample</a>.</p>

<p>the following code prints the value null in alert box. what is wrong?</p>

How to call a function from a function argument in JavaScript?

<p>So I read the tutorial from some web, and they did something like this.</p>
<pre><code>function populateDB(tx) {
tx.executeSql('DROP TABLE IF EXISTS DEMO');
tx.executeSql('CREATE TABLE IF NOT EXISTS DEMO (id unique, data)');
tx.executeSql('INSERT INTO DEMO (id, data) VALUES (1, "First row")');
tx.executeSql('INSERT INTO DEMO (id, data) VALUES (2, "Second row")');
}
function errorCB(err) {
alert("Error processing SQL: "+err.code);
}
function successCB() {
alert("success!");
}
var db = window.openDatabase("Database", "1.0", "Cordova Demo", 200000);
db.transaction(populateDB, errorCB, successCB);
</code></pre>
<p>In the last line, they called the method transaction from object db, and there are 3 functions in the argument field, but isn't the functions populateDB, errorCB both need an argument as well? Where is that argument being called?</p>

<p>Before that, i am storing the previous brightness using Shared Preference and when i am stopping my application, i am changing the brightness to the previous stored brightness.</p>

Preventing second static HTML page from loading
|
<p>I have a link on a page. When the user clicks the link a static HTML page loads. I would like to prevent the user from launching a second instance of the same static HTML document. </p>
<p>I'm thinking some javascript up front in the static HTML page might do. Basically if the script detects that there is already an instance of the static HTML document loaded then a Javascript pop-up would indicate to the user that 'document is already loaded" (something like that). </p>
<p>Anyhow, Java script is not my strong point so wondering if someone can please shed some light on this. </p>

<p>I'd like to use the code below for multiple pages. I tried putting the <code>$listloadpage</code> in an <code>array("page-1", "page-2")</code> but <code>stristr()</code> doesn't work that way.</p>
<pre><code>$currentpage = $_SERVER['REQUEST_URI'];
$listloadpage = "page-1";

{
$database->query('SELECT id, name FROM table_1 ORDER BY name', array());
$results = $database->statement->fetchAll(PDO::FETCH_ASSOC);
}

<p>this is a really basic question. I've been learning C++ and thus far I have only used the standard library. I have been including things like <code><iostream></code> and with no problems. Now I want to use Apache Xerces, so I've installed it on my machine (a Debian system) and am following a tutorial which says I need to include:</p>
<pre><code>#include <xercesc/sax2/SAX2XMLReader.hpp>

Image storage as byte code locally from XML parsing & display if it is stored Otherwise go for parsing.
|
<p>I am having an app in which at the time of launcing the app XML parsing is giving Main category from URL like hp, dell, etc...I am displaying it in the Tableview.</p>
<p>Then on click of particular cell i can get the detail of main category means its subcategory like <a href="http://www.dealsbell.com/findcoupon.php?store=hp" rel="nofollow">http://www.dealsbell.com/findcoupon.php?store=hp</a></p>
<p>Here also i am getting data properly after parsing.</p>
<p>But my concern over here is, in ( <a href="http://www.dealsbell.com/findcoupon.php?store=hp" rel="nofollow">http://www.dealsbell.com/findcoupon.php?store=hp</a> ) this link i am getting images.</p>
<p>Each particular subcategory will have a same image. So i want to do something like that the image if first time loaded from the URL then it will display image from parsing otherwise i would like to store that <strong>image as its byte code</strong> in folder / file / in any way in my device on first parsing.</p>
<p>If once the image is stored to the particular way in my device next time when i will go to see the subcategory it will first check this image is stored locally to my device or not.</p>
<p>If yes then it should go to the particular location to fetch this local image & display it to each cell otherwise will parse & display image.</p>
<p>I hope you are getting, what i want to ask.</p>
<p>Please guide me, how can this be possible & what is the way to get result.</p>
<p>If any example or link you can suggest, then it will be more efficient to me.</p>
<p>Thanks in advance.</p>

Exposing that your app is installed to the android browser
|
<p>I am trying to find a way to detect in the android browser whether my application has been installed.</p>
<p>Use case:
I have a web page that a user can reach via their android web browser. If the application is installed it would show "Tips & tricks". If it is not installed, it would show promotional material and a link to download the app.</p>
<p>Attempted solution:
My initial thoughts have been to associate my application with a custom mime type using the apps manifest and in the web page iterate javascript's mimeTypes array. I figured if the mime type showed up in the array, I could assume that the application was installed.</p>
<p>Unfortunately, the mimeTypes array doesn't ever change.</p>
<p>Any ideas how I could determine if my application is installed when the user accesses my web page via the android browser?</p>
<p>Thanks for any help / insight you might have.</p>

Jquery - Add entry to the rightclick contextmenu
|
<p>you can disable the menu</p>
<pre><code>$(document).bind("contextmenu", function(e) {
return false;
});
</code></pre>
<p>you can show a div</p>
<pre><code>$(document).bind("contextmenu", function(e) {
$('#menu').css({
top: e.pageY+'px',
left: e.pageX+'px'
}).show();
return false;
});
</code></pre>
<p>but is it possible only to add an entry to the rightclick contextmenu?</p>
<p>Thanks in advance! <br />

c++ time.h, clock_gettime(), semantic error, how to link real-time library in Eclipse?
|
<p>I have some problem using the clock_gettime() function. </p>
<pre><code>#include <iostream>
#include <time.h>
timespec timer_start;
timespec timer_end;
clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &timer_start);
// sleep for 5 seconds
boost::this_thread::sleep(boost::posix_time::milliseconds(5000));
clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &timer_end);
std::cout << (timer_end.tv_sec - timer_start.tv_sec) << ":" << (timer_end.tv_nsec - timer_start.tv_nsec) << std::endl;
</code></pre>
<p>The output I get is this</p>
<p>0:6934599</p>
<p>It seems that the timer only elapsed 693 milliseconds or so. </p>
<p>I compile the program with g++ -lrt on Linux gnu gcc 4.6. I also received a Semantic Error, says
<strong>Symbol 'CLOCK_PROCESS_CPUTIME_ID' could not be resolved</strong> </p>
<p>Thanks.</p>
