function silentErrorHandler() {return true;}
window.onerror=silentErrorHandler;

// with jQuery 
$(document).ready(function(){ /* ... */ });

// shorter jQuery version 
$(function(){ /* ... */ });

// without jQuery (doesn't work in older IEs)
document.addEventListener('DOMContentLoaded', function(){ 
    // your code goes here
}, false);

// and here's the trick (works everywhere)
function r(f){/in/.test(document.readyState)?setTimeout('r('+f+')',9):f()}
// use like
r(function(){
    alert('DOM Ready!');
});
