How can I inspect element like in Firebug via JavaScript?

Question

I need to have a user poke at an element on a website, almost exactly like with Firebug as a developer. Does anyone know a simple way to do this in JavaScript, or a library like YUI or jQuery?

Answer 1

with jquery

$("*").click(function(e){

    // do something (eg: console.log(this);)

    e.preventDefault();
    return false;
});​
