How to set timeout on $.ajax request and redo it if it takes too long?

Question

Can someone show me a practical example on setting a timeout to my $.ajax request and redo the entire request if the first request is timed out, I\'ve read the docs and didn

Answer 1

The ajax function takes a timeout parameter and you can check the status in case of error.

var call =function(){
    $.ajax({
        url: '/ajax/product.php',
        type: 'get',
        timeout: 400,
        ...
        error: function(x, textStatus, m) {
            if (textStatus=="timeout") {
                 call();
            }
        }
    });
};

You might want to make something a little smarter to avoid permanent calls...

From the documentation :

Set a timeout (in milliseconds) for the request. This will override any global timeout set with $.ajaxSetup(). The timeout period starts at the point the $.ajax call is made; if several other requests are in progress and the browser has no connections available, it is possible for a request to time out before it can be sent. In jQuery 1.4.x and below, the XMLHttpRequest object will be in an invalid state if the request times out; accessing any object members may throw an exception. In Firefox 3.0+ only, script and JSONP requests cannot be cancelled by a timeout; the script will run even if it arrives after the timeout period.
