jQuery BlockUI插件可以在不锁定浏览器的同时,模拟同步模式下发起Ajax请求的行为。该插件激活时,会阻止用户在页面进行的操作,直到插件被关闭。BlockUI通过向DOM中添加元素实现其外观和组织用户交互的行为。

一、psgInfoReport.jsp添加遮罩

<script language="JavaScript" type="text/JavaScript">
//关闭加载框
var checkExport = function(){
if(getCookie('exporting') != '1'){
$.unblockUI();//取消遮罩
}
}
//导出
var exportExcel = function(){
var startDate = $("#startDate").val().replace(/-/g,"/");
var endDate = $("#endDate").val().replace(/-/g,"/");
if(validateDateBeyond(startDate,endDate,5)){
alert("起止时间段不能超过5天");
return false;
}
var fileName = 'passengerInfoList'+$("#startDate").val().replace(/-/g,"")
+'-'+$("#endDate").val().replace(/-/g,"");
if( $('#flt_num').val()!='' ){
fileName+=$('#flt_num').val();
}
fileName+='.xls';
$('#psgInfoSearchForm').attr('action','./psgInfoSearch.html?method=psgInfoView&export=1&fileName='+fileName);
if($('#psgInfoSearchForm').form('validate')){
addCookie('exporting','1',10);//添加导出标志cookie
setInterval("checkExport()",1000);//1s检查一次
psgInfoSearchForm.submit();
$.blockUI({ message: $("#loading").html(),css:{width:'400',height:'50',border:'0'} });//添加遮罩
}else{
return false;
}
}
//页面加载时初始化
$().ready(function(){
$("select").find("option[index='0']").val("<c:out value="${psgInfoSearchForm.status}"/>");
});
</script>

</head>

<body leftmargin="0" topmargin="0">
<%@include file="/common/loading.jsp"%>
<html:form action="psgInfoSearch.html?method=psgInfoView" method="post" styleId="psgInfoSearchForm">
<input type="hidden" id='export'/>
<table width="100%" height="100%" border="0" cellpadding="0"
cellspacing="0">

</table>
</body>

</html>
二、loading.jsp遮罩加载页面
<%@ page pageEncoding="utf-8"%>
<script src="<c:url value='/scripts/jquery.blockUI.js'/>"
language="javascript"></script>

<div id="loading" style="display:none" >
<br/>
<span class="black12">正在处理,请稍等......</span><br/>
<span><img src="images/loading2.gif"/></span>
</div>
