I have a condition in which i want to show the pop up div on page load, depending on querystring. like if query string value not null or empty then i want to show popup message else close the popup.
my Code
<head>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/themes/base/jquery-ui.css"
type="text/css" media="all" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.5/jquery-ui.min.js"
type="text/javascript"></script>
<script type="text/javascript">
$(function () {
var hiddenControlValue = document.getElementById(''<%= myHiddenField.ClientID %>'').value;
if (hiddenControlValue=="true") {
$(''#dialog'').dialog({
modal: ''true'',
title: ''title''
});
}
});
</Head>
<body>
<form>
<asp:HiddenField ID="myHiddenField" runat="server" />
<div id="dialog" title="Basic dialog" style="display:none;">
<%--<p>
This is the default dialog which is useful for displaying information. The dialog
window can be moved, resized and closed with the 'x' icon.</p>--%>
<p class="txtaligncenter"> <asp:Label ID="lblLoginMsg" CssClass="failureNotification" runat="server"></asp:Label>
<asp:Button ID="btnOk" runat="server" OnClick="btnOk_Click" Text="Ok" ClientIDMode="Static"
</div>
< form>
< / body>
我的c＃代码是
protected void Page_Load（object sender，EventArgs e）
{
if（！Page.IsPostBack）
{
string isonline = Request.QueryString [Isonline];
if（isonline！ = null）
{
lblLoginMsg.Text =我在这里留言;
myHiddenField.Value =true;
}
}
这段代码真的很有用但问题是弹出式div中有一个按钮btnOk，我想在服务器端点击一下这个按钮，但我的事件没有开火
有人帮忙我

// ***this goes on the global scope
// get querystring as an array split on "&"
var querystring = location.search.replace( '?', '' ).split( '&' );
// declare object
var queryObj = {};
// loop through each name-value pair and populate object
for ( var i=0; i<querystring.length; i++ ) {
// get name and value
var name = querystring[i].split('=')[0];
var value = querystring[i].split('=')[1];
// populate object
queryObj[name] = value;
}
// ***now you can use queryObj["<name>"] to get the value of a url
// ***variable
if ( queryObj[ "delete" ] === "1" ) {
tab_crevents.show()
}
