Bind Ready function based on jQuery 1.8.2 code.
var bindReady = function (d) {
function callback() {
if (this.isReady) {
return;
}
// Make sure body exists, at least, in case IE gets a little overzealous (ticket #5443).
if ( !document.body ) {
return setTimeout( callback, 1 );
}
this.isReady = true;
d();
}
var DOMContentLoaded = function() {
if ( document.addEventListener ) {
document.removeEventListener( "DOMContentLoaded", DOMContentLoaded, false );
callback();
} else if ( document.readyState === "complete" ) {
// we're here because readyState === "complete" in oldIE
// which is good enough for us to call the dom ready!
document.detachEvent( "onreadystatechange", DOMContentLoaded );
callback();
}
};
if ( document.readyState === "complete" ) {
// Handle it asynchronously to allow scripts the opportunity to delay ready
setTimeout( callback, 1 );
// Standards-based browsers support DOMContentLoaded
} else if ( document.addEventListener ) {
// Use the handy event callback
document.addEventListener( "DOMContentLoaded", DOMContentLoaded, false );
// A fallback to window.onload, that will always work
window.addEventListener( "load", callback, false );
// If IE event model is used
} else {
// Ensure firing before onload, maybe late but safe also for iframes
document.attachEvent( "onreadystatechange", DOMContentLoaded );
// A fallback to window.onload, that will always work
window.attachEvent( "onload", callback );
// If IE and not a frame
// continually check to see if the document is ready
var top = false;
try {
top = window.frameElement === null && document.documentElement;
} catch(e) {}
if ( top && top.doScroll ) {

if ( !this.isReady ) {
try {
// Use the trick by Diego Perini
// http://javascript.nwbox.com/IEContentLoaded/
top.doScroll("left");
} catch(e) {
return setTimeout( doScrollCheck, 50 );
}
// and execute any waiting functions
callback();
}
