what do we use windows.jquery || document.write("<script src='jquery-1..2.js'><\\/script>") for ?
Sometime when we use jQuery there may be a case of loading JQuery more than one.This is an handy solution you can try in HTML5 to check whether jQuery is already included or not. If not just go for it and include it.
But do remember this stuff will not work with XHTML type documents.
