我使用 jquery 和 css 跟踪模态对话框,其中有一个登录表单。
CSS:
#mask {
position:absolute;
z-index:9000;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: rgba(0,0,0,0.8);
opacity:0;
display:none;
}
#boxes .window {
position:fixed;
width:440px;
height:200px;
display:none;
z-index:9999;
padding:20px;
}
/* Customize your modal window here, you can add background image too */
#boxes #dialog {
width:375px;
height:203px;
z-index: 99999;
background: #fff;
}
在 HTML(asp 页面)中:
<!-- #dialog is the id of a DIV defined in the code below -->
<a href="#dialog" name="modal">Simple Modal Window</a>
<div id="boxes">
<!-- #customize your modal window here -->
<div id="dialog" class="window">
<h5>Modal contents goes here</h5>
<!-- close button is defined as close class -->
<a href="#" class="close">X</a>
</div>
<!-- Do not remove div#mask, because you'll need it to fill the whole screen -->
<div id="mask"></div>
</div>
查询:
<script type="text/javascript">
$(document).ready(function () {
//select all the a tag with name equal to modal
$('a[name=modal]').click(function (e) {
//Cancel the link behavior
e.preventDefault();
//Get the A tag
var id = $(this).attr('href');
//Get the screen height and width
var maskHeight = $(document).height();
var maskWidth = $(window).width();
//Set height and width to mask to fill up the whole screen
$('#mask').css({ 'width': maskWidth, 'height': maskHeight });
//transition effect
$('#mask').fadeIn(1000);
$('#mask').fadeTo("slow", 0.8);
//Get the window height and width
var winH = $(window).height();
var winW = $(window).width();
//Set the popup window to center
$(id).css('top', winH / 2 - $(id).height() / 2);
$(id).css('left', winW / 2 - $(id).width() / 2);
//transition effect
$(id).fadeIn(2000);
});
//if close button is clicked
$('.window .close').click(function (e) {
//Cancel the link behavior
e.preventDefault();
$('#mask, .window').hide();
});
//if mask is clicked
$('#mask').click(function () {
$(this).hide();
$('.window').hide();
});
});
</script>
现在这是登录表单,我希望服务器端验证用户 ID 和密码。如果验证失败,我希望从后面的页面重新打开此对话框(使用 C#)。现在我不知道该怎么做。请给我任何帮助。
谢谢
