You need to use the "value" attribute of the radio button markup to specify a value using which you can identify two radio buttons. Use the 'onclick' event on it.

An example can be found here

I must use server side scripting and reload the webpage[same but search form differ], ... ? If a webpage contains search results how after reload retain them ?
