Question

I want to implement a function where when I click on div the high of div change 600 from 300.

Answer 1

Following script should work.

<script type="text/javascript" language="javascript">
    function resizeDiv(id)
    {
        var obj = document.getElementById(id);
        if (obj)
        {
            obj.setAttribute("style", "height:600px;");
        }
    }
</script>

Just call the resizeDiv function with proper id of the DIV tag. like :

resizeDiv('idOfDiv');
