I use the same function as event-driven as well as simulation

 

I simulate the applyTemp() function from the other function, it will shows  the error "attributes is null or not an object"

1. function applyTemp(){

2.  try{

3.    var $this = $(this);

4.    if ($this.attr('class') == 'details') {

5.    }

6.   }

7.  catch(e){

8.    alert(e);

9.   }

10. }

The same method was works well in 1.4.3
