javascript parsing

I am not sure what you meant by "javascript Parse" but, the javascript codes are executed completely on Client side (Browser), not in the Server side. However, you have to make sure that, the Javascript codes are inside the script block as follows:

<script language="javascript" type="text/javascript">
        function test() {
            alert("Hi");
        }
</script>

Otherwise, the Server side code may not give any error, but will just output the javascript codes as text in the browser.
