upgrading jquery to 1.8.0/upgrading jquery to latest version

its very easy to upgrade to latest version of jquery.  we need to take care of very few things.


1. If you are using "checked" property like below then you need to change code like below. the reason its not returning as true/false anymore.

old code:  

    if ($('#testCheckbox').attr('checked')== true && 

your new code need to be like this: 
    $('#testCheckbox').is(':checked')


2. if you have any code like below then change as per new code

old code: 
    var cType = $("select:cType").val();    

New Code
    var cType = $("#cType").val();

3. if you using validation plugin then old version of validation plugin will not be supported any more with new jquery so you have to upgrade your validation plugin also. Upgrade validation plugin to 1.9.0
