// A $( document ).ready() block.$( document ).ready(function() {console.log( "ready!" );});
Cach 2:
// Shorthand for $( document ).ready()$(function() {console.log( "ready!" );});
Cach 3:
// Passing a named function instead of an anonymous function.function readyFn( jQuery ) {// Code to run when the document is ready.}$( document ).ready( readyFn );// or:$( window ).load( readyFn );

<html><head><script src="http://code.jquery.com/jquery-1.9.1.min.js"></script><script>$( document ).ready(function() {console.log( "document loaded" );});$( window ).load(function() {console.log( "window loaded" );});</script></head><body><iframe src="http://techcrunch.com"></iframe></body></html>
