Handling errors in jQuery.getScript

Question

jQuery\'s getScript function doesn\'t seem to support an error callback function. I can\'t use the global ajax error handling code here, a local error function would be idea

This is a bit of a hack, but..

You could declare a variable inside the scripts you load and check for it after you've loaded a script (assuming that the complete-function still fires):

script_test.js:

var script_test = true;

And then:

$.getScript("script_test.js", function ()
{
    if (typeof script_test !== undefined) alert("script has been loaded!");
});

Or you could just try and see if whatever is in your script, actually exists--functions, variables, objects, etc.


A more generic way to do this would be adding a self-executing function inside the scripts you want to load, and make them execute a function in your "main" script:

main_script.js:

function scriptLoaded(scriptName)
{
    alert(scriptName + " loaded!");
}

$.getScript("script_test.js");

script_test.js:

(function ()
{
    scriptLoaded("script_test.js");
})();
