Rails spinoffs - May 2006 - Javascript Profiler

Has anyone implemented a Javascript Profiler based on prototype (or not based on
it)?

Like Venkmann? I reads somewhere it can do this?

Yep, it can. But, it''s too clutterred and too much info.

Something simple that I can put in the code like 

start()

stop()

profile()

would be cool.. :)

Unless you have some thoughts (articles) on profiling in venkman.

Thanks,
Mandy.

Try this as a start.

var Benchmark = new function(){
  this.starttime = [];

  this.start = function(text) {
    this.starttime.push([new Date(), text || ""]);
  }

  this.stop = function(){
    var start = this.starttime.pop();
    if (!start) return;
    var dauer = (new Date()) - start[0];
    this.show(dauer, start[1]);
  }

  this.show = function(zeit, text){
    var wo = document.createElement("div");
    wo.innerHTML = (new Date().toTimeString()) + " " + text + "
-> " +
zeit + " ms";
    document.body.appendChild(wo);
  }
};

Benchmark.start();
// something
Benchmark.start("Showing foo");
// show foo
Benchmark.stop();
//something else
Benchmark.stop();

Bye,
