Jquery的blockUI使用 js弹出层
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
Java代码
1.<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
2.<%
3.String path = request.getContextPath();
4.String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
5.%>
6.
7.<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
8.<html>
9. <head>
10. <base href="<%=basePath%>">
11.
12. <title>My JSP 'JqueryShowBlock.jsp' starting page</title>
13.
14. <meta http-equiv="pragma" content="no-cache">
15. <meta http-equiv="cache-control" content="no-cache">
16. <meta http-equiv="expires" content="0">
17. <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
18. <meta http-equiv="description" content="This is my page">
19. <!--
20. <link rel="stylesheet" type="text/css" href="styles.css">
21. -->
22. <script language="JavaScript" type="text/javascript"
23. src="<%=path %>/jquery/jquery-1.2.3.js"></script>
24. <script type="text/javascript" src="<%=path %>/jquery/jquery.blockUI.js"></script>
25. <script language="JavaScript">
26. function showBlock(){
27. jQuery.blockUI({ message: "处理中，请稍候...", css: {color:'#fff',border:'3px solid #aaa',backgroundColor:'#CC3300'},overlayCSS: { opacity:'0.0' }});
28. setTimeout('hideBlock()',2000);//2000毫秒后调用hideBlock()
29. }
30. function hideBlock(){
31. jQuery.unblockUI();
32. }
33. </script>
34.
35. </head>
36.
37. <body>
38. This is my JSP page. <br>
39. ShowJqueryBlock Start:<input type="button" id="showBlock" value="ShowBlock" onclick="showBlock()"/><br/>
40. </body>
41.</html>
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。
