JQuery弹出层示例可自定义

1、创建一个jsp页面，内容如下，js和css根据自己的实际情况而定

<%@ page language="java" contentType="text/html; charset=UTF-8" 
pageEncoding="UTF-8"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<title>Insert title here</title> 

<link href="Share.css" rel="stylesheet" type="text/css"> 
<script type="text/javascript" src="../js/common/jquery-1.11.0.js"></script> 
<script type="text/javascript" src="popup.js"></script> 
<script type="text/javascript" src="testPopup.js"></script> 

</head> 
<body> 
<div id="right"> 
<div class="right_nav"> 
<h1>用户管理</h1> 
<a href="#" onclick="" class="but_tj">添加</a> 
</div> 
<div class="overlay" id="spm" style="display: none;"></div><!-- 将弹出层下面的页面变成不可操作状态，成半透明状态 --> 
<div class="Popup" style="display: none">,<!-- 隐藏div --> 
<div class="Popup_top"> 
<h1>添加</h1> 
<a href="#" class="Close"><img alt="关闭" src="close.png" /></a> 
</div> 
<div class="Popup_cen"> 

<table width="100%" border="0" cellspacing="0" cellpadding="0" class="BD_tab"> 
<tr> 
<td style="width: 110px;" align="right">姓名：</td> 
<td><input name="" id="name" type="text" class="input220" 
onfocus="this.className='input220L';this.onmouseout=''" 
onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" 
onmousemove="this.className='input220Lg'" 
onmouseout="this.className='input220'"> <font color="red">*</font></td> 
</tr> 
<tr> 
<td align="right">昵称：</td> 
<td><input name="" id="nickname" type="text" class="input220" 
onfocus="this.className='input220L';this.onmouseout=''" 
onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" 
onmousemove="this.className='input220Lg'" 
onmouseout="this.className='input220'"> <font color="red">*</font></td> 
</tr> 
<tr> 
<td style="width: 110px;" align="right">账号：</td> 
<td><input name="" id="account" type="text" class="input220" 
onfocus="this.className='input220L';this.onmouseout=''" 
onblur="this.className='input220';this.onmouseout=function(){this.className='input220'};" 
onmousemove="this.className='input220Lg'" 
onmouseout="this.className='input220'"> <font color="red">*</font></td> 
</tr> 
</table> 
</div> 
</div> 
</div> 
</body> 
</html> 

2、公用的带有弹出层和关闭层的两个方法

复制代码代码如下:

//popup layer 
function isIE(num){ 
var num = num || "", 
tester = document.createElement('div'); 
tester.innerHTML = '<!--[if IE ' + num + ']><i></i><![endif]-->'; 
return !!tester.getElementsByTagName('i')[0]; 
} 
function popupLayer(objClass,targetClass){ 
$("."+objClass).click(function(){ 
$("#spm").show(); 
var target=$("."+targetClass); 
var targetWidth=target.outerWidth(); 
var targetHeight=target.outerHeight(); 
if(isIE(6)){ 
$("#spm").hide(); 
//$("select").hide(); 
var top=$(document).scrollTop()+$(window).height()/2; 
target.css({"top":top+"px"}); 
$(window).scroll(function(){ 
var top=$(document).scrollTop()+$(window).height()/2; 
target.css({"top":top+"px"}); 
}); 
} 
target.css({"margin-top":-parseInt(targetHeight/2)+"px","margin-left":-parseInt(targetWidth/2)+"px"}); 
target.show(); 
return false; 

}); 

} 
//隐藏div的操作 
function closeLayer(objClass,targetClass) 
{ 
$("."+objClass).click(function(){ 
$(this).parents("."+targetClass).hide(); 
$("#spm").hide(); 

}); 
} 

3、1中调用3中js实现效果的js代码

复制代码代码如下:

$(function(){ 
//第一个参数是按钮的class属性值，第二个是被隐藏的div属性值 
popupLayer("but_tj","Popup"); 
closeLayer("Close","Popup"); 
}); 

//我们通过点击添加或修改按钮后使当前操作的div隐藏 
//closeAdd("Popup"); 
function closeAdd(targetClass){ 
$("."+targetClass).hide(); 
$("#spm").hide(); 
} 

4、css样式

复制代码代码如下:

html {min-height: 100%;position: relative;overflow: hidden;} 
body {background-color: #FFF;font: 12px 微软雅黑, Arial, sans-serif;margin: 0;} 
h1 {font-size: 12px;font-size: inherit;font-weight: normal;} 
a {text-decoration: none;} 
a:hover {text-decoration: none;} 
.clear {overflow: hidden;clear: both;} 
#right {margin-left: 190px;min-height: 100%;padding: 0;} 
.right_top {height: 40px;background-color: #f5f5f5;color: #666666;border-bottom: 1px solid #e5e5e5;line-height: 40px;padding-left: 50px;position: relative;z-index: 1;} 
.right_top a {color: #2b7dbc;} 
.right_nav {margin: 0 30px;height: 37px;background-color: #438eb9;line-height: 37px;position: relative;margin-top: 15px;}

.but_tj:hover {background: url(but_JG1.png) no-repeat;} 
.pind20 {padding-left: 20px;} 
/*Popup*/ 
.Popup {width: 770px;height: 500px;position: absolute;left: 50%;top: 50%;margin-left: -400px;padding: 0 15px;margin-top: -250px;background-color: #FFF;border: 3px solid #006caa;z-index: 999;} 
.Popup_top {height: 40px;line-height: 40px;border-bottom: 1px solid #cccccc;} 
.Popup_top h1 {float: left;font-size: 14px;} 
.Close {float: right;font-family: Arial, Helvetica, sans-serif;margin-right: 10px;margin-top: 10px;}

.overlay {position: fixed;z-index: 990;width: 100%;height: 100%;top: 0;left: 0;filter: alpha(opacity = 60);opacity: 0.6;overflow: hidden;background-color: #000;} 
/*BD_tab*/ 
.BD_tab {width: 500px;margin: 0 auto;} 
.BD_tab td {padding-top: 12px;} 
.input220,.input220L,.input220Lg {width: 220px;height: 28px;border: 1px solid #d3d3d3;padding-left: 5px;line-height: 28px;font-family: "微软雅黑";color: #000;} 
.input220L {border: 1px solid #377bcb;background-color: #d5e8ff;} 
.input220Lg {border: 1px solid #7fb1eb;background-color: #d8e6f7;} 
.input220 {border: 1px solid #d3d3d3;}
