[jQuery] Re: How to control order of events or wait until something is loaded?

[Gonzo]

getScript doesn't wait for the script to finish loading before
continuing, so you are trying to call validator.setDefaults before the
validator exists.

This should work:

function setupValidator() {
        $.validator.setDefaults({
                submitHandler: function() { alert("submitted!"); }
        });
}

if (typeof($.validator) == 'undefined') {
        $.getScript("/javascript/jquery/jquery.validate.js", setupValidator);
} else {
        setupValidator();
}
