 2     $(document.body).infinite().on("infinite", function() {
 3         $("#loadingID").css("display","");
 4         if(loading)return;
 5         loading = true;
 6         setTimeout(function() {
 7         var pageNo=parseInt($("#currPage").val(),10)+1;
 8             searchData(pageNo);
 9             loading = false;
10         }, 1000);

16             searchData(1);
17             $(document.body).pullToRefreshDone();
18         },1000);
19     });    

<div class="weui-pull-to-refresh-layer">
