向ASP.NET RadioButton控件添加自定义属性 [英] Adding custom attributes to asp.NET RadioButton control

问题描述

我想向名为 Key 的asp.net单选按钮添加自定义属性，我正在使用客户端的ajax请求.

I want to add a custom attribute to an asp.net RadioButton called Key which I'm using client-side for an ajax request.

我发现的是我的aspx标记，如下所示:

What I'm finding is that my aspx markup which is the following:

<asp:RadioButton ID="rdoPost" GroupName=PreferredContactMethod" value="Post" onclick="DoStuff(this)" runat="server" />

在页面中呈现为

<span Key="ContactMethod">
   <input id="rdoPost" type="radio" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />
</span>

我期望(并希望)获得以下信息

whereas I'd expected (and hoped) to get the following

<input id="rdoPost" type="radio" Key="ContactMethod" name="PreferredContactMethod"" value="Post" onclick="DoStuff(this);" />

我已经尝试过使用asp TextBox控件进行相同的操作，并且它完全可以按我期望的那样工作，只需将 Key ="myKey" 属性添加到< input type ="text"/> 元素.

I've tried the same thing with an asp TextBox control and it works exactly as I'd expect simply adding the Key="myKey" attribute to the <input type="text"/> element.

使用标准RadioButton控件是否可以解决此问题，还是必须继承自标准按钮才能实现所需的标记?

Is there a way around this with the standard RadioButton control, or will I have to inherit from the standard one to achieve the markup I'm wanting?

也...(很抱歉同时问两个问题)，将非标准属性添加到html标记中还是个坏主意吗?目前，我正在通过以下方式在JavaScript中使用这些属性:

Also... (sorry to ask two questions at the same time), is adding non-standard attributes to html markup a bad idea anyway? Currently I'm using these attributes in JavaScript in the following way:

var key = rdoPost.Key;

推荐答案

我从下面的问题/答案中发现，最简单的方法是使用 InputAttributes 属性如下:

I've found from the question/answer below that the easiest way to do this is via the code-behind using the InputAttributes property as follows:

rdoPost.InputAttributes.Add("class", "myCheckBoxClass");

为什么ASP.NetRadioButton和CheckBox在Span内渲染?
