Forcing postback on selection of a radio button

I know this is simple开发者_高级运维 as cake but I've been using ASP.NET controls for way too long. I assume you have to do this via javascript with a regular XHTML input tag?

To redirect to a URL after selecting a radio button:

<input type="radio" name="myRadio" onclick="window.location.href='/my/desired/url.aspx';" />

---

You can simply call a javascript method that sets window.location

function redirect() {
  window.location = 'http://whatever...'
}
