I'm sure someone has written about this, but my google-fu is utterly failing me!Say I make an ajax request:
javascript Code:

errQueryFailure = new Error ("Server query failure");

I want window.onerror type functionality in webkit.
Is there any way of doing this?
My best attempt was:
Code:
Which breaks Chromes console, but doesn't get triggered for internal errors (e.g. reference errors).
I'm trying to implement a php style __autoload.
Essentially I think it's possible to
-Catch the error
-Find out the name of the object which isnt referenced
-Try to include a JS file with the same name
I have the following simple ajax call in a .ready() function :

I have a shopping cart where if a user have problems of buying products or transactions, I want to give support via a chat programme. I want to reply users in different chat threads not like in a chat room as other people dont want to see others chat.I am new to this subject.
View 3 Replies View RelatedI'm trying to load some javascript files via ajax, I can't get it to catch 404 errors. I've tried searching, but everything I've found says that I should check the status on the request object to catch it but it's not even getting that far.
I've tried:
I would try $.getScript, but that appears to have no way of handling errors. I've even tried just doing a console.info("test") -- it doesn't even do that. Firebug shows a 404 error (obviously) but the error doesn't seem to be being caught? I'm loading jquery through the google api, version 1.3.2.
I'm having a problem with the returning a php variable from my ajax php handler.
I call the handler...
if(ajaxRequest.readyState == 4 || ajaxRequest.readyState == 0){
var ajaxDisplay = document.getElementById('ajaxDiv');
var refreshID = "";
var timeout = "<?=$timeout?>";
ajaxDisplay.innerHTML = ajaxRequest.responseText;
//Change Refresh Timeout Based on Remaining Song Length
refreshID = setTimeout("DoRefresh()", timeout);
DoRefresh() function is the ajax function. What am I doing wrong?
How can we identify logical errors from other types of errors?
View 4 Replies View RelatedI'm having a weird problem using ajax. I use ajax to create a input field inside a form.
like this:
Before Ajax script
Code:
After Ajax script
Code:
The Ajax script works perfectly. the problem occurs when I try to send the form with the new field. The form doesn't send the field data to test.php. And more weird is that it works on IE, only on FF the problem occurs. Nothing shows in the Errors Console, and I have the last Firefox version.
i'm new to ajax. simple request no problem - but it seems when I set
the response handler function, I can only pass the function name and
not give parameters, so I have a problem when starting e.g. 5 ajax
requests parallele. how to do that correctly? for one case, where I
used *different* resp. handlers, I solved the problem by global
variables - but now I have a loop of e.g. 20 calls to the *same*
r.handler and I don*t know how to tell the function *which* request of
the 20 to use. I expect the solution to be simple but how..
I'm trying to bind an event handler to a button in a page loaded via Ajax. This procedure should apply to every page I have to load via Ajax. I have tried two things: first, I declared the 'click' event handler for the button like this, and just did my ajax request. Here's the code:
$("#close_button").click(function(){
alert("This should popup");
});
$.ajax({
url: 'js/ajax/text.html',
[Code]...
What is the event handler for the Ajax.Autocompleter?
Is it onKeyUp or onChange?
I'd like to display the results using a button for example.
I have never really bothered with javascript before but i am having alot of problems with a ajax php form my php code returns
if ($states==false)
{
$result = 'nostates';
$result = trim($result);
return $result;
[Code]...
I would like the results of a simple form to be posted on a (private) web page, from which I can generate an email reply.
View 4 Replies View RelatedI have the following code:
$(document).ready(function(){
$('#link').click(function() {
alert('Clicked!');
$('#content').load('dialogs/load/content', function() {});
});
});
The link is a normal link that is not dynamically created. The alert works. I know the problem is not the Ajax call because this works just fine:
$(document).ready(function(){
$('#content').load('dialogs/load/content', function() {});
$('#link').click(function() {
[Code]....
It only breaks when located inside the click handler. It does not return response headers or a response. Is there something about event handlers and ajax that I'm missing?
Goal 1: display errors above the form on same page
Goal 2: direct users to a new thankyou page when form is submitted.
The form uses ajax. I am able to get it to work with the error messages displaying correctly but as is, the thankyou message also displays in the same spot and the form is left filled out. I need it to direct to a new page I designed for the purpose.
Has anyone tried working out this one?
How to detect IE4 without wrongly detecting IE5.0 (IE5.0 usually returns a navigator.appVersion of 4.0)
Here's the code im working with using substring of IE version:
// <head>
<script language="JavaScript">
this.version = navigator.appVersion;
</script>
// <body>
<script language="JavaScript">
if (navigator.appName == "Microsoft Internet Explorer"){
if (version.substring(0,1) <= 4){
if (version.substring(22,23) <= 4){
document.write("This Browser is IE4 or lower!");
}
else{
document.write("This Browser is IE5 or higher!");
}
}
}
else{
document.write("This Browser isn't IE!");
}
document.write("<br>This Browser is " +version);
</script>
The version string usually return's something like this:
4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
Can anyone see any problem with using this method?
I am trying to catch keypresses in my canvas tag, but it appears that
that is not valid.
I may try to just create a hidden input box that will allow me to catch
keypresses.
I am trying to write a very simple asteroids game for a presentation on
Ajax in July, to show that javascript can do more than it was able to a
couple of years ago.
Is there a way to catch when a div content is updated through javascript? I update a div content through rjs and I need to call tablesorter every time the div is updated.
View 3 Replies View RelatedCan I get information from other frame, like form values or variables?
View 5 Replies View RelatedI have a main page ('index.php') with an iframe ('mainframe') on the
left hand side. All the links on the index page load a new page of
mainly text content into the iframe.
All pretty straightforward, but I am using some javascript to launch
and hide a floating div on the index page (if I launch it in the
iframe, it will be restricted to the height and width of that frame).
The code to show / hide the div is located on the page index.php - say
the function is called 'showMe()', I would call top.showMe() to launch
the div.
The Div works fine, but when I try and catch an event via:
event.srcelement
it returns the error message 'object required', because it is being
passed from a link on a totally seperate page (the iframe)...
Is there any method for the main page (index.php) to catch the event
on 'mainframe' that triggers the div ?
The div's do show up and hide, and I can load source content into them
- only error messages keep flashing up on IE (but not on Netscape /
Firefox, etc).
How may I catch all postback events which are triggered by all controls using jQuery in an ASPX page?
I am using the below provided code and displaying an alert window when any control posts back to the server, however not all postbacks are getting caught by the highlighted code.

{
if (Request.ServerVariables["REQUEST_METHOD"] == "POST" || Request.ServerVariables["REQUEST_METHOD"] == "GET")

I have a page contained in an iframe. The page contained in the iframe shows videos all the time.Each video has an id that changes when a new video is played.I need to be able to catch this changing id in the page that has the iframe (the parent page) and that is hosted in a different server from the contained page.The only languages that can be used in the contained page are javascript, ajax and jquery
In the parent page you can use these languages + php.
I'm not posting the contained page code just because, believe me, it's humongous,full of variables and functions from other files and modules.The only thing needed there is a variable, myid, that stores the new id when a new video is played.Then I have to post, send, throw ... etc. myid and after that catch it in the parent page, remembering that myid's value changes when a new video is played and that.I have to get that new value at all times.I have to get the value of the playing video id to do things like changing the background of the page depending on the video played or showing a webpage depending on the video played ... and so on.
This is the code I am using to test this. In FF and Op. When I click on an option in the select box, the alert pops up. In IE and Chrome, it doesn't seem to catch it at all.
$('.clickopt').mousedown(function(){
alert("test");
});
Catching <a> link click - Fancy Box I have an example here of the simple image gallery I'm working with. The thumbnails are loaded from an XML and are linked to larger images. untitled I want to use Fancy box Fancybox - Fancy lightbox alternative to show the larger images. I have fancy box working on other sites but can't get it to work here. In an attempt to work out why it's not working I tried to capture the click on the <a> link, but that won't work.

It would be easier to explain this if you play mafia wars (or any game that includes intra-game exchange of gifts/items between members) but the actual scripting doesn't require any knowledge of the game.
Background Information
Mafia Wars is a game on Facebook (and myspace, yahoo etc.) that among other things allows its players to send gifts to each other. Now because different people end up with more things of one type and are short of things of another type, the players have evolved a trading dynamic. Where x number of Item 1 is traded for y number of Item 2. A simple marketplace. And with this territory come scammers.
Essentially a player who doesn't go through with his end of the deal. good player sends item to bad player. bad player removes good player from mafia and blocks him for ever contacting him through his facebook profile. This has given rise to my group, among many others, that lists these scammers (identified with their facebook profile ids) as they are reported every day. Now over time the list has grown and it has become difficult and unrealistic to expect people to know who is on the list and who is not.
The Requirement
A javascript bookmarklet (there are many already servicing different needs of the players) that sits on the browser and tells the user if the person he is about to trade with is a listed scammer or not.
The Breakdown
The user will click the bookmarklet when he is on the facebook profile of the person he is about to trade with. When clicked the script will pull the facebook profile id from the current page, and then scan a text file located on a third-party server and return with a pop-up box message that reports if the id is listed as a scammer or not.
If visual basic and firebug doesn't show me any error and if code doesn't work on any browser...so what should i do. I did a little boring - to read my code again to find a simple syntax errors like - writte() for exemple.
But even that does not give me anything! Is there any good recomendations how to change it all?
Look at this code:
Browser gives me out only - Please enter a valid name
