包括jquery-1.2.3.js和jquery.blockUI.js
2.在前臺JSP頁面中調用Jquery
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'JqueryShowBlock.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
<script language="JavaScript" type="text/javascript"
src="<%=path %>/jquery/jquery-1.2.3.js"></script>
<script type="text/javascript" src="<%=path %>/jquery/jquery.blockUI.js"></script>
<script language="JavaScript">
function showBlock(){
jQuery.blockUI({ message: "處理中，請稍候...", css: {color:'#fff',border:'3px solid #aaa',backgroundColor:'#CC3300'},overlayCSS: { opacity:'0.0' }});
setTimeout('hideBlock()',2000);//2000毫秒後調用hideBlock()
}
function hideBlock(){
jQuery.unblockUI();
}
</script>
</head>
<body>
This is my JSP page. <br>
ShowJqueryBlock Start:<input type="button" id="showBlock" value="ShowBlock" onclick="showBlock()"/><br/>
</body>
</html>
關於jquery文件的目錄結構如下：
---WebRoot
--------jquery
-----------jquery-1.2.3.js
-----------jquery.blockUI.js
3.頁面執行結果如下：

當點擊"ShowBlock"按鈕時會調用jquery的jQuery.blockUI方法，"處理中，請稍後..."的jquery的block信息會顯示，並且將頁面鎖定；過2000毫秒後調用jQuery.unblockUI()將jquery的block信息取消。
