Jquery的blockUI应用 _Web前端

Jquery的blockUI使用
1.首先要准备好关于jquery的js文件
包括jquery-1.2.3.js和jquery.blockUI.js
2.在前台JSP页面中调用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: "处理中，请稍候...", css: {color:'#fff',border:'3px solid #aaa',backgroundColor:'#CC3300'},overlayCSS: { opacity:'0.0' }});
		            setTimeout('hideBlock()',2000);//2000毫秒后调用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>

关于jquery文件的目录结构如下：
---WebRoot
--------jquery
-----------jquery-1.2.3.js
-----------jquery.blockUI.js
3.页面执行结果如下：

当点击"ShowBlock"按钮时会调用jquery的jQuery.blockUI方法，"处理中，请稍后..."的jquery的block信息会显示，并且将页面锁定；过2000毫秒后调用jQuery.unblockUI()将jquery的block信息取消。
