[jQuery] Re: event data ?

[Michael Geary]

Using the name "btn" for the event function parameter will surely make
things confusing - because you'll be looking for it to be a DOM element for
the button, which it isn't. The parameter to the event function is an
*event* object.

Inside the function, "this" refers to the button element, and so does
"event.target".

The best way to see what the btn object is all about is to download
and install firebug. Then use the console to output that object. for
example:

$('.mybutton').bind('click',function(btn){ console.log( btn); } );


Then on the console panel of firebug, you'll see the btn object, which
is clickable. If clicked, firebug will show you the DOM representation
of that object and all of its properties that are accessible.

Thanks .. but I still curious what is inside the variable that passed
through function callback (btn in my example) and how to have access
on it.

[motob]

$('.mybutton').click(function(){
  alert($(this).attr("id")); //get the id
  $(this).attr("disabled", "disabled"); //disable the clicked button
});
