What should be that ?

Please refer the JSFiddle

http://jsfiddle.net/

You have to select the jQuery version and then type the jQuery in javascript column. clicking on the JsLint button will pop you if any errors.

You can check it on JSLint.

Here's the first message I got when entering my code in jsLint: '$' was used before it was defined. (on http://www.jslint.com/)

On the other hand, jsfiddle (http://jsfiddle.net/) provides a jsHint button (at the header bar) that understands jQuery and neatly flags mistakes. Also the TidyUp button sets the indentation properly! I already used that site but missed those features, now I'll use it much more.
