tab用jquery写的上文中的javascript最后写成这个样子了

$(function()
{ 
 var $jj=$("#navs li"); 
 var $kk=$("#neirongk div");    
    for(var i=0;i<$jj.length;i++)
                               {(function(i){$($jj[i]).mouseover(function(){for(var j=0;j<$kk.length;j++){(function(j){
          $kk[j];
          if(j==i)
          {$($kk[j]).show(500);}
          else
          {$kk[j].style.display="none";}})(j);}})})(i);}});
