Get ActiveTabIndex from Ajax TabContainer using Javascript
提问by Troy Mitchel
How would I get the ActiveTabIndex from TabContainer when the user selects a tab? I've tried the following but does not work.
当用户选择一个选项卡时，如何从 TabContainer 获取 ActiveTabIndex？我尝试了以下但不起作用。
<script type="text/javascript">
function TabChange() {
var tc = document.getElementById("TabContainer1")
alert(tc.ActiveTabIndex);
}
</script>
<asp:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" Height="300px"
Width="300px" CssClass="MyTabStyle" OnClientActiveTabChanged="TabChange">
<asp:TabPanel runat="server" HeaderText="First" ID="TabPanel1">
<ContentTemplate>
<h1>
Tab 1
</h1>
</ContentTemplate>
</asp:TabPanel>
<asp:TabPanel ID="TabPanel2" runat="server" HeaderText="Second">
<ContentTemplate>
<h1>
Tab 2
</h1>
</ContentTemplate>
</asp:TabPanel>
</asp:TabContainer>
