JQuery :: Jsonp Callbacks Execution Order In Firefox
Apr 6, 2010
I am trying to develop a iGoogle-like dashboard that uses JSONP to get the content of each widget from other (trusted) sites.Each widget is a div that will take care of getting its content using $.ajax() and use the callback to update the div with the html content returned with JSONP.The problem I have happens only in Firefox (I'm using 3.6.3):when a site is unavailable or takes longer to return the JSONP content for a widget, it seems that the callback for the other widget does not get executed. All the widgets stay in the "loading" state although I'm sure they have all received the answer.What's puzzling is that if I hit the "stop" button of Firefox, the content of the other widgets get displayed (ie. their displaying callbacks get executed).
If the calls are asynchronous, what prevents Firefox from executing the callbacks for the other widgets once the response is received?Do you have any idea of what's happening and if there's some way around this?

It prints 0,1,...,9, but you cannot see the word "hi". It seems that it prints "hi" then executes the listnum function. But the listnum function is placed before "hi". Could you
give me some info on order of execution?
<HEAD>
<SCRIPT language=JavaScript>
function listnum() {
i=0
do {
document.write( i + "<br>")
i++
} while(i<10)
}</SCRIPT>
</HEAD>
<BODY onload=listnum()>
hi
</BODY>

I would like to have two actions for one event. But I want the second action to trigger when the first one action completes. Is it possible to do this in javascript? I'm using the onclick event.

Currently I was able to load remote JSON (php) file using JSONP protocol. However, how to do if my remote file is static? In the doc, it said: you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". But since my remote file is a static text file, how can I specify the callback in the output dynamically? In fact, I also wonder if it is possible to control the random callback name by modifying jquery source code...

I'm trying to use $.ajax to make a JSONP call, but the callback function is never executed.I have debugging code in my server that acknowledges that a request is received, but that never runs.The same URL works fine if I paste it into the address bar of my browser.

I'm having problems with callbacks in the code below:
$.ajax({
dataType : 'jsonp',
jsonpCallback : 'get_json',
success : function(d) { alert(d); },
error : function() { alert("ouch"); },
url : data_url
})}
I have verified that the server is returning valid json. My jsonpCallback is called, but neither the success nor the error callbacks are. I'm stumped by this.

how to use jQuery I created my own AutoComplete Textbox (although there is one in the jQueryUI Lib). The users types something in a textbox and after 3 characters, the getJSON method is beeing called. This processes the data by calling another site and after received the data, it displays the result in a div tag.If a user types something, it automatically searchs - my problem is the delay. Because if a user continuous, he will already receive (delayed) results - so far it works as designed. My question is, how can I stop the other callbacks of being processed and only receive and display the details of the last callback?

I found this post: [URL] It explains exactly what I want to do. The person who had the problem seemed to have sorted it out but as my knowledge is not to great I am not to sure what he is getting at. I tried various things but to no avail. All I want to do is return data to a calling javascript using type get and datatype jsonp. If I simply Response.Write "[(""id"": ""123""}]" then nothing happens. So whatever the thread I revered to above is doing it seems to be going in the right direction.

If this is synchronous, normal json request, I can capture the result (data) and return it to a calling function.
However jsonp is not synchronous. Whilst the data IS returned, and I can view it from within the success function, but I cannot access it after that.
$.ajax({
url: remote_url,
async: false,
cache: false,
[Code]....
I am building a library of functions which call this function, so I cannot have the data processing done within the success function, I need to extract the data itself.

I have some jQuery making ajax requests that works just fine if the server returns a 200 but whenever it returns any error HTTP status none of the events fire. It's happening on more than one request to different servers but I'll just include one example for now:
var ajaxResponse = $.ajax({
url: widget.serviceURL + 'customer/createAjax?'+$('#ndBookingFormStep1').serialize(),
dataType: 'jsonp',
success: function(data, textStatus, jqXHR){
console.log(data);
if( data.status != 'OK'){
widget.message(data.status);
} else {
console.log(data);
}}})
.error(function(jqXHR, textStatus, errorThrown){
console.log(jqXHR);
}).complete(function(jqXHR, textStatus){
console.log(jqXHR);
});
console.log(ajaxResponse);
console.log(ajaxResponse.responseText );
The request gets made just fine, I can see the response in the net console in firebug and it returns the data I want with a 500 when I do not complete the form correctly. However, it does not fire either the error or the complete function when I get this status, and the ajaxResponse.responseText is undefined when it is logged to the screen. When the form is completed and the request is successfull the success function fires just fine.

I'm tryng to develop a link tracker, something like google analytics. The goal is to get a command like this:
$('html').trackAllLinks(optional options);
$('a').trackAllLinks(optional options);
Now i developed a javascript that could do just what i need but the problem is it doesn't work in every browser as it should be. Because i want to track a link click i need to make a request to my server to say that the link has been clicked. The first problem i had was that i needed to make a cross domain ajax call. But this is fixed by using JSONP. Now my code looks like this:
[Code]...
The first idea was that i wouldn't do anything in the success of the jsonp call and just let the request go, but because this didn't work when i clicked on an external link, i changed it to wait on a response before opening the link. The problem with this code is that it doesn't work in Opera, no request is being send to the server Now i know that JSONP mimics the ajax call by adding a script tag to the page which loads the script of the given url. Now i think when i do this in Opera the dynamically loaded javascript isn't executed. In Firefox, IE, Chrome, Safari it works but not in Opera.
Another idea i had was by dynamicly adding an image to the page. But this has the same problem in Opera and i was unable to track an external link in Safari and Chrome (Webkit.

I have jQuery 1.5.1 client-side that is making an .ajax() call to an ASP.Net MVC controller method - expecting a jsonp packaged response. In normal cases, the server packages up a response of typeapplication/json and that works fine. The problem is when the session on the server times out, the server will respond to the ajax call with the server's login page, which obviously isn't valid json and the error handler on the ajax call fires with a parseerror. Similarly, if there's an exception server-side, the site redirects to a custom error page, which again isn't valid json, and: barf. I have no information client-side what went wrong when in the .ajax error handler. The xhr just says parseerror with no further info. Is there any way I can see what the server responded with so I can handle this more intelligently? I've tried change the client-side dataType to "json text" hoping that it would try to interpret the server response as text, if the json fails, but it just goes to the error handler.

Really excited about the new 1.4 release. Looks like a lot of good stuff. Anyway, I've been using the json format to pass data back from the server and after upgrading to 1.4 I'm getting the parsererror, even when I simplify my response to something like:
In php I've been using:
To set the header.
Guess I'm stuck using the older version until I find a solution.

So I have a function that is going to get a URL, and have to retrieve json data from that URL. The URL _might_ be same-domain, and might be cross-domain. If it's cross-domain, of course I want to do jsonp complete with the script-tag-to-load and such, but if it's same domain of course I want to do just xhr for efficiency. So I _could_ write all my own logic for this. Write logic to see if the url is cross-domain or not, and then make entirely different $.ajax() calls depending.
(I think I need to use $.ajax() rather than $.getJSON() because I need a callback on failure, not just success). If it is cross-domain, use dataType:jsonp, and make sure to supply a &callback. If it's not cross-domain, dataType:json, and don't even bother supplying a callback. But I'm having trouble figuring out if this is true, or how. What's the easiest way to get $.ajax() to make a dataType:json request if it's same-domain, but a dataType:jsonp request if it's cross-domain?

The documentation on e.g. the fadeIn() method does not specify any constraints on the callback argument. Does that mean that 'anything will work'? Specifically, is recursion allowed?I want to know whether jQuery design has deliberately taken this into account. Yes, I can read the source code. No I don't plan to do so (for now), since I consider it an essential gap in the documentation.[code]

I'm using an .ajax() call to do a jsonp request to another domain. When the user is not logged in, however, the server will return a 401 error. Unfortunately, this causes my .ajax() call to fail _without_ calling the error callback. Is this a known bug? Here is my code:

There is probably something going on in my environment but when running 1.5.2, jquery runs and behaves fine. When I switched to 1.6.1 immediately the success callbacks of ajax functions did not trigger. I did not see the release notes mention anything new regarding that.
This includes
$.post("url", function() { console.log("will i get printed?"); });
Here is a code sample which fails
$(".foo").click(function(e) {
var link = $(this);
e.preventDefault();[code].....
The callback function for the ajax is never invoked.As part of my application, I have the following ajax setup going
$.ajaxSetup({
'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}
});
Firefox 4.0.1, Ubuntu 10.04, Firebug 1.7

I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?

I currently have a situation where I have images that load when a user scrolls to the bottom of a page. I also have part of the same function call .remove() on the top 2 images if the number of currently loaded images exceeds 10. The trouble that I am having lies in the .remove() is causing the scrollbar to move down, calling the image-loading part of the function again (essentially a chain reaction of image loads and elements being removed if a user scrolls down while images are being loaded).
I was wondering if I can use setTimeout or a similar function to prevent .remove() from executing until images have been completely loaded?
$("#message").html(calcScroll);
if (calcScroll == 0 && curPageIndex + 1 < totalCount) {
$("#message").html("loading new images");
window.setTimeout(function () {

i have the following two pieces of code:
function slideOut() {
var $slidy = $('#slideout');
$slidy.animate({
right: parseInt($slidy.css('right'),10) == 0 ?
-$slidy.outerWidth() :
[Code]...
As long as i return false and the link is an anchor, i can see the menu slide out. Which is quite clear to me why. When i use a link with a href on another page though, the "jump" is executed before the animation ends most of the time even before it starts.
I would like the click to be delayed weather a certain condition kicks in, or some time passed to end the slide and then jump to the new page. I have been looking throughout the web and found no hint helping me to tackle this. delay() and setTimeout() dont seem to work the way i used them.
I am sure there is a way, its just the blind man's stick in my eye that keeps me from it. I hope someone can help me with this.
