Javascript And Submit Button

Hi all!

How do I convert this code into the Yii code using submit button




<!DOCTYPE html>

<html>

<script>

function calculate(value)

{

	return value*value;

}

</script>

<body>

<form NAME="Calc">

	<table BORDER=4>

		<tr>

			<td>

			<input TYPE="text"   NAME="input" id='txtBox' Size="16">

			<br>

			</td>

		</tr>

		<tr>

			<td>

			<input TYPE="button" NAME="DoIt" VALUE =' = '  OnClick="Calc.input.value=calculate(Calc.input.value)">

			<br>

			</td>

		</tr>

	</table>

</form>

</body>

</html>		







I am following this type of style for my projects.

Careful on single and double quotes
