JQuery :: "Mysterious" Error Ajax Callback On Window Unload?

Jan 14, 2012

We have an Ajax error callback that notifies the user that something went wrong. The ajax call takes some time, and sometimes the user navigates away while the ajax is in progress.

That causes the error callback to be fired. However, in the error callback I can't seem to detect that the reason for the error is that the page is unloading so as to distinguish this from other errors. In the callback, this is true: (textStatus === "error" && errorThrown === "" && jqXHR['status'] === 0 && jqXHR['statusText'] === "error").

JQuery :: Error Callback Fires Every Time In Ajax

Oct 19, 2011

What I noticed is that my error callback is fired every time.
MyService.asmx:
[WebMethod]
public FileInfo[] GetFileInfo(int Id){
Proxies.ServiceRef.ServiceClient c = new Proxies.ServiceRef.ServiceClient();
return c.GetFileInfo(Id).ToArray();
}

The Jquery code where I am getting error:
$.ajax({
url: url,
data: jsonData,
type: "POST",
contentType: _I.contentType,
timeout: _I.timeout,
dataType: "serviceproxy", // custom type to avoid double parse
dataFilter: function (jsonString, type) { .....

When I debug using firebug the response is as follows.
{"d":[{"__type":"Proxies.AFARServiceRef.AssignmentInfo","ExtensionData":
{},"AssignDate":"/Date(1317748587667)
/","AssignFileName":null,"ClaimId":"PA026195","ClaimantName":"Rachel

JQuery :: .ajax() With DataType: 'jsonp' Will Not Use Error Callback If Request Fails?

Oct 1, 2009

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:

JQuery :: Star-rating Plugin Callback Function Throwing Error?

Jan 9, 2009

I'm using this star-rating plugin [URL] and the call back function provided to allow for submission of forms onclick of rating star.

Code:
$(document).ready(function() {
$('form.entry_rating').rating( {
callback:function(value, link) {
alert(value);
}
});
});

However, once the callback is included I get an error I've been trying to track down for the past day and a half. In IE the error thrown is "Object doesn't support this property or method" on Line 100 character 4. In my JS debugger the plugin breaks on line 99

JQuery :: Ajax Success Callback In Firefox4?

Aug 18, 2010

today I updated my Firefox from 3.5 to 4.0b3 and it seems that the AJAX success callback is not longer fired. Firebug shows the correct response but the function is never called. Is this a Problem of the FF Beta, or is Jquery responsible for this?

Here is my Script

success: function(data) {
console.log('success');

JQuery :: Access Data Outside Ajax Callback?

Apr 2, 2011

The answer to my question is probably very simple, but I'm having trouble making this work.

I want to access a local csv file, rearrange it into an array, and use the data later in my script. The logic of this in psuedocode is [code]...

Since the massaged data are in the callback, they're not available at ***. I've tried declaring the variables outside the callback as shown, but this doesn't seem to work either. I'm thinking there must be an easier way. Is there?

JQuery :: Ajax - Access Data Arguments In Callback?

Sep 17, 2009

Is it possible to access the data arguments that are sent with the ajax function? Example:

$('#mycheckbox').click( function() {
$.get( '/ajax.php', { nr: this.id }, function( data, textStatus ) {
// Here I want to access the arguments I just sent with ajax.php

[Code]....

I could easily do $('#mycheckbox').attr('checked', 'checked'); but that is not what I want. Also I don't want to send the arguments with the response. Anyone knows a solution? I can't find it in the documentation of jQuery and not in the discussions here.

JQuery :: Asp.net Mvc 3 - Validate Only A Portion Of The Form When Doing An AJAX Callback?

Sep 23, 2009

I have a web page that has a few text boxes, and a dual list control. All of these data elements are for a particular entity. The form is for creating a new instance of this entity and saving it to the database. The dual list shows available people to use, and the user can move options from the available list to the selected list. All of this works perfectly when posted. There is a button at the bottom of the page to post the form.

To make things easy, I also want to include a hidden "form" that lets the user add a new person to the dual list without leaving the page. They click an "Add New" link which shows a previously hidden div. In the div are two text boxes: "emailName" and "emailAddress", and a button to click called "Add".

When the user clicks the "Add" button I need to validate the emailName and emailAddress fields, and only those two fields. If they are valid then I will make my AJAX request and handle the return data by adding a new option to the dual list.

JQuery :: How To Get Ajax Response Data To Outside Callback Function

Aug 19, 2009

I have Javascript code that looks like this:
var data1;
$.post('save_search.php', formData, function(data) {
data1 = data;
});
jsonData = eval('(' + data1 + ')');
if (jsonData.return_status.search("successful") > -1)
$('#msg_div').html("<font color=red>Search was saved</font>");
else
$('#msg_div').html("<font color=red>Search was not saved. Try saving again.</font>");
"data1" comes up as undefined in the statement
jsonData = eval('(' + data1 + ')');

Even though "data" is a perfectly correct JSON string *inside* the callback function! I can put the eval statement inside the callback function and it will form a good JSON object, like this:
jsonData = eval('(' + data + ')');
I'm simply trying to get my Ajax response data to the outside of my callback function so I can use it in other Javascript code. I've never seen an ordinary function behave this way.

JQuery :: Load Part Of Page With Ajax And BeforeSend Callback

Dec 10, 2009

I would like to achieve such thing, as to load some part of other page, like this:

$("#content").load("example.com/main.htm #content > div");

but I need to do a beforeSend callback, to fade out the current content, wait until it is fully hidden, and only then fade in with the received ajax request. But doing this, for example, with .ajaxSend, the content loads much quicker, then fadeOut is complete.

JQuery :: Callback Function Required To Make Ajax Call

Jul 15, 2010

On a project I got stuck on this "problem". When you make a json (ajax) call. You also need a callback function. Which means I have to call the next $.getJSON within that callback function to read the next portion of data. In my opinion this is not very readable code...What I want is a nice and readable piece of code. Where you could just write it like this:
var data1 = $.getJSON(..);
var data2 =$.getJSON(..);
I've found a solution here: [URL] (explains my problem perfectly). But it's not compatible with the getJSON story. Is there already a possibility to do this with the jquery library?
