JQuery :: Ajax Calls Success Method On Timeout Instead Of Error
Sep 1, 2010
I've noticed this weird behaviour of jQuery in Safari and Chrome (didn't test on Firefox as I'm using some webkit CSS extensions). After setting up the call like this:
If a timeout occurs (I switch the local webserver off), the 'success' method will be called! More than this in the textStatus parameter there is a string with "success" !!! The error handler doesn't even get called.... (As you may notice the only way I had to tell the problem, was to check the data param if it is null or 0 length. How can I avoid this?
I'm currently rewriting all my ajax calls to use the jquery method (much cleaner code! ) and have declared a default ajaxError function, shown below:
$(document).ajaxError(function(event, request, settings){ alert("There was an error while communicating with the server. URL: " + settings.url); });
However, now I have a few ajax calls where I want to declare an error function in the ajax call. I was hoping that by declaring an error function in the ajax call, it would replace the default error call I have defined. But that does not appear to be the case, as I continue to first get my ajax function error call, then I also see the above code execute.
I tried calling event.stopImmediatePropagation() from within my ajax error function hoping that it would stop further events firing (ie: the default error event) but that didn't do anything except tell me in firefox that "event" was undefined.
I was hoping I wouldn't have to go through and define an error function to EVERY ajax call.
I am trying to call a dynamically chosen function on success from an ajax call (later to be error and so on also)The following function works fine and passes the url to call and parameters into the makeAjaxPostCall function. successHandler is the function to call on ajax success.[code]
I wanted to ask how it is possible to get error messages from the server till it is implemented in the remote method.What do you think is the less work intensive alternative.I also wanted to ask if i have two fields A and B, and the values of B depends on A. How do i make it with the plugin and the remote method ?I saw that there is a way of writing custom methods:URL...But how do i combine it with the ajax calls?
But problem is that It doesn't execute the If-else condition. In firebug I have seen the console the response and html both displays "ok" even if I prompt the value of data it displays "ok" but when I debug the code it appends character along with the value .Another thing is that is it possible to put the entire ajax code into a function and based on the value it return after success full execution I return Boolean value to calling function.I have tried this but it always returns false.
I can't use the value returned by $.post() method out of the scope of success function.
For instance in below example myvar alerted as empty even though var is alerted with a value. Besides, hide does not work in the scope of success function.
Now, I am having one problem with the .ajax() function. My problem is, the timeout value seems to be completely ignored. [code]...
The idea is that when the underlying hardware is restarted (this is a control page for a device), we should time out very quickly, rather than locking the browser. I have stepped though with a debugger, and the 250ms value is definitely being inserted when the reboot command is issued. Any idea why this is not working?
No matter what I put in here, Firefox is going into the error; will not return success.What the server returns is just plain text, no html, thinking maybe it has something to do with This, but I can't figure it out because there are only So many options for
For some reason the success and error callbacks are not working at all. I'm using jquery.ajax to submit a form w/o page refresh through a php file. I have set the success & error callbacks but even when I changed the mysql password (to a incorrect one) I got the success message [code]...
I'm using getJSON to load data from the database onto a form. How can I specify the success & error callbacks? here's the code I'm using: EDIT: I managed to get the success callback by adding it below the $('fontSize')... but how can I set the error callback?

I have what I think is a simple $.ajax() call.I added complete and error functions but a time out in firefox 3.5.2 doesn't cause the error function to be called and when the complete function is called both parameters are undefined.If I make the ajax call return a http 500 response the error function is called.[code]Running on FF 3.5.2, JQuery 1.6.2 on XP Pro.
I'm developing a jquery web application. On start the user gets a login screen to sign in (verification and session checking is done by php). After login the user gets the application screen where most of the server communication is done by ajax (json). If there was no ajax communication for a long time (timeout), the server (php) sends a session timout (something like error=timeout) and wants the user to sign in again. Now comes the tricky part:I want to show a window where the user enters the login information. Now the application should send these information to the login.php and after acknowledgment, the last ajax request should be sent again.Is there a possibility to send an ajax request again with same settings?
I am working on an ASP.NET application that make a lot of jquery and javascript calls and trying to optimize the client side code as much as possible. (This web application is only designed to run on special hardware that has very low memory and processing power.)
The profiler in firebug is great for figuring out what calls are taking up the most time. I have already optimized a lot of my selectors and it is much faster.
However the profile shows a lot of jquery error() calls. In the attached image of the firebug profile window you can see it was called 52 times, accounting for 15.4 of the processing time.
Is that normal for jquery to call its error() like that? My code works flawlessy, and there are no error messages in the firefox error console. It seems like that is a significant performance hit. Is there anyway to get more info on what the errors are?
My app recently upgraded to 1.4 and as such started using the XMLHttpRequest in the success callback of the .ajax function however we been forced to roll back to 1.3.2 due to performance issues with IE7 (forced to use in a corporate environment) Is there any way to get access to the XMLHttpRequest after an ajax call? If not, would anyone be so kind as to point out if its possible to modify the 1.3.2 source to add the parameter to the success call back like in 1.4? I am hoping its a simple modification however I could be wrong. We are set to upgrade to the lastest jQuery when we get a browser upgrade to IE9 but that could be up to a year away and I would really like to continue to use the XMLHttpRequest in my app as its a lot faster than my old approach.
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?
And i have gone through this forum and other forums for a simple fix ... since so many have had this problem..but i have nt found anything that seems to work hence i am posting this problem
I dont know what i am doign wrong i have used debugbar and i can seethe html content that comes back i have used fiddler and i see hte html content that comes back there....the xhr stat =200 so every thing is good..yet it doesnot replace the the content $("#updateroster").html(data).
I'm working with a few more variables than this, I'm working with 3 variables. What I'm wondering is should I use json_encode() on the php side. I will be using php validations, so I may return error messages in an array. How do I check whether I have error messages or true value.
I'd like to send in an associative array so I can have email = "error"; amongst a few others. So if email is the only one with error I will .append a message to the correct div id.
My web page consists of 3 js jquery.js, a.js and b.js. This js are in order one after the another as posted. I have ajax call in a.js $.ajax inside a function fun() and this function is getting called from b.js function fun()return the value objtained from ajax call.No here is the tricky thing. Everything executes fine but in my b.js from where i am calling fun i am not able to get the returned by fun;But if i simply have an alert box then i am able to get the value/I tried jquery ajax with asynch attribute as false But still no results
iam developing online quiz contest project in php (mysql,javascript,ajax) i need Automatic session timeout/logout and also i need time counter display using php and AJAX.
I'm so happy my jquery is dispatching a serverside script (ajax) and it is working I have verified in the database.Now I would like to provide some feedback to the user so first go will be alert, later I will do something snazzy.I am just getting head around jQuery, so please excuse noobness of question. I will think that either one or the other of these alerts below would fire, but neither of them do and nothing also logs in the console.
