Hi could someone help me figure out how to stop a function running until a specific number of characters are pressed?

currently using the following function:

$('input#q').keyup

this works as soon as you press any key...

Something like this should start firing code after 3 letters have been added:

JavaScript

$('input#q').keyup( function() {

   if( this.value.length < 4 ) return;

   /* code to run below */

   $('#output').val(this.value); 

});

HTML

<input id=q />

<br /><br />

<input id=output/>
