<form action="" onsubmit="return dosubmit(this)">      <label for="password">password</label>        <input type="password" id="password" maxlength="20" size="10"   required="true" pattern=".{7,}" title="password should atleast 7 characters long"/>   <br /><br />      <label for="confirm">confirm password</label>        <input type="password" id="confirm"" maxlength="20" size="10" required="true"   />    <br /><br/>       <label for="mcq">mcq</label>       beginner<input type="radio" name="url"  value="tyrano.html"required="true"/>                 <br />        expert<input type="radio" name="url" value="spino.html"required="true"/>                 <br /><br />  <button type="reset"  id="reset">reset</button>      <button type="submit" id="submit">submit</button> </form> 

to redirect other page, javascript has location.href work.

document.getelementbyid("id_of_your_radio").onclick = function() {     location.href = "you_redirected_url"; } 

try , see works.
