如何在客户端处理SelectedIndexChanged事件 [英] How to handle the SelectedIndexChanged event in client side

问题描述

大家好，
我有RadioButtonList和面板.当我在列表中选择特定项目时，我想使面板可见.我将此代码写在代码隐藏文件中，如下所示:

Hi all,
I have RadioButtonList and Panel. I want to make a panel visible when I choose a specific item in the list. I wrote this code in the code-behind file like this:

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (RadioButtonList1.SelectedIndex == 3)
            Panel1.Visible = true;
        else
            Panel1.Visible = false;
    }

如何在客户端实现此功能?如果有多种方法，请提及它们.

在此先谢谢您.

How can I implement this in the client side? if there are more than one way please mention them.

Thanks in advance.

推荐答案

请确保已在代码内设置了AutoPostBack="true".
然后在客户端脚本中编写此代码.

请参见示例此处 [

Make sure you have set AutoPostBack="true" inside the code.
Then write this code inside a client script.

See the example here[^].
