向getScript（）添加超时

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)

$.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.

Since getScript doesn't accept timeout option. You can use ajaxSetup method to set global timeout.

If global timeout isn't applicable you can use

$.get({
  url: a + "/myspeed/MySpeedServer/mss/js",
  timeout: 5000, // 5 seconds
  dataType: "script"
});
