I'm developing a listing of workers, where the user can by department  select  through of tag select (html). But, my jQuery function not works in IE 8. 

1. 1. function popularFuncDeptos(){  
   2.         var sigla = $("#sel_depto").val();  
   3.         if(sigla != "all"){       
   4.                 $("#listas").load('/ReconhecimentoNew/funcionario/depto/' +sigla+ ' #list_depto',  
   5.                 function(){           
   6.             $("#list_all").hide();  
   7.             $("#list_depto").show();  
   8.         });  
   9.         } else {      
   10.             $("#listas").load('/ReconhecimentoNew/funcionario/depto/' +sigla+ ' #list_all',  
   11.                     function(){           
   12.             $("#list_depto").hide();  
   13.             $("#list_all").show();  
   14.             });  
   15.         }

Could anyone help me?
