使用ThickBox登录过程小实验
ThickBox是一个基于JQuery的小组件，用于提供像windows关机那样效果的网页的制作，只有20K，下载地址以及Demo在http://jquery.com/demo/thickbox/，使用时共有6个文件需要下载，它们是:
jquery-latest.js
loadingAnimation.gif
macFFBgHack.png
thickbox.css
thickbox.js
thickbox-compressed.js
(其中thickbox.js和thickbox.css里要指定另两个图片的位置)
准备好后，下面开始用Jsp/Servlet编写一个ThickBox的小例子：
1.欢迎页面 index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
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%>">
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/thickbox.js"></script>
<title>TestThickBox</title>
<link rel="stylesheet" href="css/thickbox.css" type="text/css" media="screen" />
</head>
<body>
<h1><a href="Login.jsp?keepThis=true&TB_iframe=true&height=150&width=300" class="thickbox" title="Login">Click to Login</a></h1>
<br>
</body>
</html>
里面重要的是?keepThis=true&TB_iframe=true&height=150&width=300，其效果是上层的box带有标题栏并且点击Box以外的区域时返回原来状态。
(注意<script type="text/javascript" src="path-to-file/jquery.js"></script><script type="text/javascript" src="path-to-file/thickbox.js"></script>以及<link rel="stylesheet" href="path-to-file/thickbox.css" type="text/css" media="screen" />的位置)
2.LoginServlet
package MyServlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class LoginServlet extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
String name = request.getParameter("name");
out.println("<html>");
out.println("<head>");
out.println("<title>Greeting</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello " + name + "</h1>");
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}
/**
* Handles the HTTP <code>GET</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Returns a short description of the servlet.
* @return a String containing servlet description
*/
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}
3.登录页面Login.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
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 'Login.jsp' starting page</title>
</head>
<body>
<form method="post" action="LoginServlet">
<p class="STYLE1">Please input your name and click OK button. </p>
<p>
<input type="text" name="name">
<input name="buttonOk" type="submit" id="buttonOk" value="OK">
</p>
</form>
<br>
</body>
</html>
4. 修改web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>MyServlet.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
好啦 Tomcat部署下看看吧
页面:
ThickBox:
点击OK后
最后列一下文件目录:
