推荐答案

您可以使用onchange事件，它是客户端事件，可以调用javascript并检查任何内容

you can use onchange event that is client side event you can call javascript and check whatever

function Checking() {
           alert('test')
           }

<asp:radiobutton id="RadioButton1" runat="server" onchange="Checking()" xmlns:asp="#unknown" />

首先，您的单选按钮中不应autopostback ="true"

First there should not autopostback="true" in your Radio button

<tr>
                                       <td>
                                           <asp:radiobutton id="Radio1" checked="true" runat="server" text="Text" groupname="rd" xmlns:asp="#unknown" />
                                       </td>
                                       <td>
                                           <asp:radiobutton id="Radio2" runat="server" text="Image" groupname="rd" xmlns:asp="#unknown" />
                                       </td>
                                   </tr>

然后使用jQuery，它将像这样:

then using jQuery it will get like this:

(文档).ready(函数(){

(document).ready(function () {
