Ajax Call timeout

Question

I'm currently using a light javascript library to make ajax calls. The library is 'jx'.

And it works fine. But I would like to add a timeout in order to stop the ajax call if there is no response after a certain time. I looked around and it doesn't seems there is a timeout parameter like with jquery...

Is there a way to implement a timeout thanks to a pure javascript? Like this :

timer = setTimeout('function{stop the call}', 20000);
jx.load(url, function(data){ 
        // get the data
        clearTimeout(timer);
        }

I tried that and it's not working well ... is there an other way to do that? Or to make the ajax call syn

Fix your code. Instead of 'function{stop the call}' it should be function() { stop the call }. Also, I would put the timeout after the ajax call. — PitaJ

The timeout after the ajax call? why? and at the end of the timer how can I stop the call? — Guillaume le Floch

The lib you're using doesn't have a cancel handler, so You won't be able to do it with this library, sry. And, I guess it wouldn't really matter where you put the setTimeout, it's just a personal preference. — PitaJ

@PitaJ see my answer, it seems the library stores the XMLHttpRequest object into a http variable. — bfavaretto

If this is the library you're using, it seems to be possible:

var xhr = jx.init();
var timer = setTimeout(function(){ 
    if(xhr && xhr.abort) xhr.abort();
}, 20000);

jx.load(url, function(data){ 
    clearTimeout(timer);
});

Yes I'm using this library :) I'm gonna try that right now! Thanks you!

I just added the code you pasted me. It seems like it never calls jx.http.abort(). So I get my error message thanks to the timer and then I get the response from the ajax call.

Looked at jx source again, and it seems I got it wrong the first time. Could you try the updated code above?

@GuillaumeleFloch Are you sure you're using the latest version (3.01A)? jx.init() is supposed to return the xhr object, but in the line by line explanation they seem to use 3.00A, and init returns undefined.

I'm gonna update the version I think I run an oldest version ... Thanks!
