JS提交表单带滚动条

前提：需要用户自行搜索wait.gif滚动条图片，并且需要引入JQuery.js。

1.编写JS方法ShowDIV

function ShowDIV(thisObjID) {
     $("#BgDiv").css({ display: "block", height: $(document).height() });
     var yscroll = document.documentElement.scrollTop;
     $("#" + thisObjID ).css("top", "100px");
     $("#" + thisObjID ).css("display", "block");
  document.documentElement.scrollTop = 0;
 }

 

2.在提交表单的js中调用DIV层

 // 提交表单

 function doSubmit(){
  sendForm.action = "<%=request.getContextPath()%>/gotoSwdxfsjsqk.do?method=swdxfsjsqk";
  sendForm.submit();
  ShowDIV('DialogDiv');
 }

 

3.将如下语句块放到</script>后

<style>
 #BgDiv{background-color:#e3e3e3; position:absolute; z-index:99; left:0; top:0; display:none; width:100%; height:1000px;opacity:0.5;filter: alpha(opacity=50);-moz-opacity: 0.5;}
 #DialogDiv{position:absolute; left:50%; top:50%;  margin-left:-200px;margin-top:10%; height:auto; z-index:100;}
</style>

 

4.将如下语句放到</form>前

<div id="BgDiv"></div>
<!--遮罩层显示的DIV1-->
<div id="DialogDiv" style="display:none">
   <img src="<%=request.getContextPath()%>/pic/wait.gif" />
</div>
