How to get active tab index from TabContainer
提问by NealR
Currently I am using this line of code in my JavaScript
目前我在我的 JavaScript 中使用这行代码
var tabIndex = $(':focus').attr('tabIndex');
However this constantly fails to get the active index.
然而，这总是无法获得活动索引。
Here is asp:TabContainer header in case this helps. I have also tried document.GetElementById, however to no avail as well.
这是 asp:TabContainer 标头，以防万一。我也尝试过 document.GetElementById，但也无济于事。
<asp:TabContainer ID="AdvOrBasicSearch" runat="server" ActiveTabIndex="0">

I found this method works much better. I created a variable with the tabContainer itself. Then, I just needed to go inside the variable and pull the value from the _activeTabIndex property.
我发现这种方法效果更好。我用 tabContainer 本身创建了一个变量。然后，我只需要进入变量内部并从 _activeTabIndex 属性中提取值。
var tabIndex = $find("AdvOrBasicSearch"); //AdvOrBasicSearch is name of tabContainer
var i = tabIndex._activeTabIndex;

I have used jQuery here. With it it is simple to find what you want. Pay attention to the rectangled text in the pic.
我在这里使用了 jQuery。有了它，很容易找到你想要的东西。注意图片中的矩形文字。
Happy coding.
