一:图片预览

1)层默认是隐藏的,当点击“点击”按钮时会出现效果

2)在此之前分别倒入jquery-1.4.4.min.js和jquery.easydrag.handler.beta2.js(用于拖动层)两个文件

3)图片:



二:代码片段:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
