制作Lightbox效果

制作Lightbox效果

  • Lightbox是网页上常用的一种效果,比如单击网页上某个链接或图片,则整个网页会变暗,并在网页中间弹出一个层来。此时,用户只能在层上进行操作,不能在单击变暗的网页。
  • 程序代码

    <%@ 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>
    <style type="text/css">
    .black_overlay {
    display: none; /*    默认不显示 */
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%; /*  以上四条设置覆盖层和网页一样大,并且左上角对齐 */
    background-color: black; /*  背景为黑色 */
    z-index: 1001; /* 位于网页最上层 */
    -moz-opacity: 0.7; /*   Firefox浏览器透明度设置 */
    opacity: .70; /* 支持css3的浏览器透明度设置 */
    filter: alpha(opacity = 80); /*  IE浏览器透明度设置 */
