向getScript（）添加超时

Question

I'm using the getScript() JQuery method but could really do with adding a timeout. Some scripts don't come back as failed for a good 6-8 seconds, which is too long.

Is this possible?

I've searched a bit and no solutions have been forthcoming.

Something like:

$.getScript(a + "/myspeed/MySpeedServer/mss/js")
        .done(function() {
            //do stuff
        })
         .fail(function() {
            //do stuff
        });
         .timeout(2000)

Answer 1

$.getScript is simply a wrapper around $.ajax(). Hence, you could use $.ajax() with the timeout option as below.

$.ajax({
    url: url,
    dataType: "script",
    timeout: 2 * 1000
}).done(function() {
    //do stuff
})
.fail(function() {
    //do stuff
});

A note from the doc: 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.

You may also use the abort() method as stated here.
