jQuery click() event not firing on AJAX loaded HTML elements

Do this.

 $(document).on("click",".sframe",function(e){
 var seat_number = this.id.match(/\d/g);
 alert(seat_number); 
 });

or

 $(document).delegate(".sframe","click",function(e){
 var seat_number = this.id.match(/\d/g);
 alert(seat_number); 

 });

Edit:

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate().
