How to store the value of attribute ID to a variable? Jquery Javascript

Question

Ok, so this is probably obvious.

I need to get the ID of a clicked div:

$("div.editable").click(function(e) {  
  var editid = $(this).attr("id");  
});

And the use that ID in a function w/parameters:

ajaxStyle(value, 2, editid)

But it doesn't work when I write it like this. It either returns "undefined" or just doesn't work.

var editid;
$("div.editable").click(function(e) {
   editid = $(this).attr("id");
});

It's all about function scope.

You are declaring your editid variable within a function, so it is only visible within it and not defined outside of it.

This will work (though will pollute the global namespace):

var editid;
$("div.editable").click(function(e) {  
  editid = $(this).attr("id");  
});
