        Today I am going to show you how to perform some basic operations on checkbox using Java

<script type="text/javascript">
function change()
var s = "You like ";
var cntr = document.form1;
s += cntr.check1.value;
s += " " + cntr.check2.value;
<form action="" name="form1">
<input type="checkbox" name="check1" value="CD">CD</input>
<input type="checkbox" name="check2" value="DVD">DVD</input>

<input type="button" onclick="change()" value="Like" />

        In above example we created two checkbox check1 and check2 inside form form1 the value of check1 is CD and check2 is DVD and a button bounded with javascript function change() on the onclick event. When user checks any one or both boxes and clicks the button then change() function gets called and alert the value of checked boxes.
        We can get which checkbox is checked or not by document.form1.check1.checked and for value use document.form1.check1.value.
