Question

I am using the below code:

<div class="business-bottom-content" onMouseOver="javascript:this.className='business-bottom-    content-hover';"  onMouseOut="javascript:this.className='business-bottom-content';"> 

The jQuery script is as following:

 $("div.business-bottom-content").click(
 function()
  {
   alert('ashutosh mishra');
  });

You probably define the div after the script has executed.

Wrap it in $(document).ready(function() { .... }); to ensure it executes after the full DOM is available.

Additionally you should get rid of those ugly inline events (if you even need them – you can use :hover in CSS):

$('div.business-bottom-content').hover(function() {
    $(this).addClass('business-bottom-content-hover');
}, function() {
    $(this).removeClass('business-bottom-content-hover');
});
