Question

I want to try some different options with some javascript (jQuery) to see which is the fastest, however I can’t get profiling working properly. Here is the code I want to test.

    $this.keypress(function(e) {
        console.profile("test");

        //retrieve the charcode if possible, otherwise get the keycode
        k = e.which ? e.which : e.CharCode;

        if (blockKeyCodes.indexOf("|" + k + "|") != -1 || e.ctrlKey && k == 86)
            e.preventDefault();

        console.profileEnd();
    });

However, when I run this the console states “no activity to profile”. If I use console.time the result is 0ms.

Anyone know how to fix this?

Firebug profiler does not give the time taken by native methods, wrap entire functionality into a function and call that function between profile start and end.
