From jQuery doc :
The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.
We can set several distinct values for a single element and retrieve them later:
$('body').data('foo', 52);
$('body').data('bar'...
It must be emphasized that the data is associated with the DOM object, not the jQuery object:
var a = $('div label');
var b = $('div label');...
The above usage is just a shorthand for jQuery.data(domElement, key) .

Firefox and Google chrome has native support for the trim function for a String. IE (as of IE 8.0) does not provide a trim function for String. Using the JavaScript Executor , if you execute:
'abcd '.trim
you get:
function trim() { [native code] }
in Firefox and Google Chrome. But you get nothing in IE. If you try to execute the trim method on a String:
'abcd '.trim()
you get this in IE:
TypeError: Object doesn't support this property or...
In order to have the trim function across all browsers, define this function:
if(typeof String.prototype.trim !== 'function') {
...
Or, if you use jQuery, you can use $.trim()
