do something when function executes Jquery

Question

So I have a function that is recursive for inverting colors. Here is the code:

function invert(id,what){
    var color = $(id).css(what);
    var matchColors         


        

Answer 1

Wrap your function.

var wrapped = (function wrapper(present) {
    function wrapping() {
        ++wrapping.count; // increment invocation count
        return present.apply(this, arguments);
    }
    wrapping.count = 0; // counter, avaliable from outside too
    return wrapping;
}(invert));

If you need to call it invert too, re-assign invert after.

invert = wrapped;
invert.count; // 0
invert();
invert.count; // 1
invert();
invert.count; // 2
