You just need javascript to do this job. Ajax is used to send asynchronous request to the server and get back response. As far as DOM manipulation is concerned only javascript is needed.

THis code will help you:

<html>
	<head>
		<title>test</title>
		<script type="text/javascript">
			
			function showForm() {
				var radio1 = document.getElementById('radio1');
				var radio2 = document.getElementById('radio2');
				
				if(radio1.checked == true) {
					hideForm2();
					showForm1();
					alert('1');
				} else {
					hideForm1();
					showForm2();
					alert('2');
				}
			}
			
			function showForm1() {
				var divForm = document.getElementById('divform1');
				divForm.style.visibility = "visible";
			}
			
			function hideForm1() {
				var divForm = document.getElementById('divform1');
				divForm.style.visibility = "hidden";
			}
			
			function showForm2() {
				var divForm = document.getElementById('divform2');
				divForm.style.visibility = "visible";
			}
			
			function hideForm2() {
				var divForm = document.getElementById('divform2');
				divForm.style.visibility = "hidden";
			}
		</script>
		
		<style>
			#formContainer {
				position: relative;
				top: 100px;
			}
			
			#divform1 {
				position: absolute;
				top: 0px;
				left: 0px;
				visibility: hidden;
			}
			
			#divform2 {
				position: absolute;
				top: 0px;
				left: 0px;
				visibility: hidden;
			}
			
		</style>		
	</head>
	
	<body >
		<form id='myform'>
			<input type='radio' id='radio1' name='formSel' value='1' onClick="showForm();">Form-1</input>
			<input type='radio' id='radio2' name='formSel' value='2' onClick="showForm();">Form-2</input>
		</form>
		
		<div id="formContainer" style="border: 1px solid #000;">
			<div id="divform1">
				<form id="form1">
					<h1>Form1</h1>
				</form>
			</div>
			
			<div id="divform2">
				<form id="form2">
					<h1>Form2</h1>
				</form>
			</div>
		</div>
	</body>
</html>

Thanx for giving solution for that,


But i want to initially when we will not click any radio button means by default it will not show any form . so how it i can do pls tell me.

how about using some jQuery to simplify the code even further.

<html>
<head>
<title>test</title>
<!-- Let GOOGLE serve the ajax library via their CDN -->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
	//Run the hideall() function to hide all divs that have an id of divform
        //and are children of the node with id formContainer
	hideall();

	//Listen for a click event on ANY input with an id of formRadio
	$("input[id='formRadio']").click(function () { 
		//capture the value of the radio the click occurred on
		var value = $(this).val();
		
		//Run the hideall function again to make sure everything is collapsed
		hideall();
		
		//toogle the visibility of the div the click occurred on by its index value
		//index values start at 0 and increment by 1
		//first divform has index of 0 second has index of 1 etc etc
		$("div[id='divform']:eq(" + value + ")").toggle();  
	});	
	
	function hideall()
	{
		$("#formContainer > div[id='divform']").hide();
	}
});
</script>
<style>
#formContainer {
	position: relative;
	top: 100px;
}
</style>
</head>
<body >
<form id='myform'>
  <input type='radio' id='formRadio' name='formSel' value='0'>
  Form-1
  </input>
  <input type='radio' id='formRadio' name='formSel' value='1'>
  Form-2
  </input>
</form>
<div id="formContainer" style="border: 1px solid #000;">
  <div id="divform">
    <form id="form1">
      <h1>Form1</h1>
    </form>
  </div>
  <div id="divform">
    <form id="form2">
      <h1>Form2</h1>
    </form>
  </div>
</div>
</body>
</html>

In this example you can now add an infinite amount of forms and as long as a radio button exists they will all expand and contract on click without having to write any additional javascript.

There are some minor changes to the form as provided above.
