今天特想写一个基于ajax.net的模态窗口的例子,但是中间出现了很多的问题,但统统被我拿下,呵呵呵!下面就让我写出我的成果吧。
同样是使用的是AjaxPrio,有关设置的问题就不多说了,直接进入正题。
先给出模态串口的代码;

<style>

div.titleBar{background: #CC66CC;margin: 0px auto;width: 100%;height: 21px;border: #0000FF solid 1px;}
3
div.closeButton{float: right;}
4
div.mainBody{margin: auto;}

#divModalDialog{border:solid 1px;background:white;POSITION: absolute;left:0px;top:0px;DISPLAY: none;height:200px;WIDTH: 350px;overflow:hidden}

#divModal{BACKGROUND-COLOR: white; FILTER: alpha(opacity=75); LEFT: 0px; POSITION:absolute; TOP: 0px;overflow:hidden}

</style>
下面是模态窗口的html
<style>2
div.titleBar{background: #CC66CC;margin: 0px auto;width: 100%;height: 21px;border: #0000FF solid 1px;}3

#divModal{BACKGROUND-COLOR: white; FILTER: alpha(opacity=75); LEFT: 0px; POSITION:absolute; TOP: 0px;overflow:hidden}7
</style> 1
<body>

3
<DIV id="divModal" style="z-index: 100"></div>
4
<DIV id="divModalDialog" style="z-index: 101" >
5
<div class="titleBar">
6
<div class="closeButton"><a href="javascript:closeModal();">[关闭]</a></div>
7
</div>
8
<div class="mainBody" id="mainbb">
9
<div>
10
</DIV>
11
<form id="form1" runat=server >
12
用户名:<input id="username" type="text" /><br />
13
密码:

<input id="userpwd" type="password" /><br />
15
<input id="Button1" type="button" value="登陆" language="javascript" onclick="return Button1_onclick()" />
16
</form>
17

然后就是cs文件了

这基本上就是全部了,但需要注意的是,模态窗口在html页面是可以正常显示的,但在.net中却出现了问题,div的位置改变了,这个问题是我最头疼的问题,找了好多的资料都没找到答案,但突然有个念头闪过,就是把<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">给删了,果然成功了,但为什么删除我就不清楚了,呵呵呵!
