 1         var strs = new Array();

 3         function getData() {
 4             var strs2 = new Array();
 5             $.ajax({

10                 success : function(msg) {
11                     strs2 = msg.list;
12                     total = msg.total;
13                     pagetotal = msg.pagetotal;
14                 }
15             });
