引入js

 1 var len = 500 ;
 2     var add = 0 ;
 3     function openContenFrame(){
 4         var td1 = document.getElementById(‘tdOne‘) ;
 5         var td2 = document.getElementById(‘tdTwo‘) ;
 6         add = add+10 ;
 7         td1.width = add ;
 8         if(len - add <= 0){
 9            td2.width = 1 ;
10         }else{
11            td2.width = len - add ;
12         }
13         if(add<=len) {
14            ;
15         }else{
16            td1.width = 1 ;
17            td2.width = 500 ;
18            add = 0 ;
19         }
20         setTimeout(‘openContenFrame()‘,100) ;
21     }
22     function loading(){
23         document.getElementById("load").style.display="";
24         document.getElementById("opperate1").style.display="none";
25         document.getElementById("opperate2").style.display="none";
26         openContenFrame();
27     }

注意：使用loading函数到需要的提交的action之后
