Javascript return String to Html

Question

Beginner question: I would like to pass in window.location.hash to my form action parameter. How can I do this with a javascript call?

my current non-working code is:

<form method="POST"
    action="j_security_check"+window.location.hash>

Your javascript needs to be based on some kind of event. So you might want to do it when your submit button is pressed or something:

<form method="POST" action="">
<input type="submit" value="Submit" onclick="this.form.action = 'j_security_check'+window.location.hash" />

-1 The javascript doesn't need to be based on any event to execute.

<form name="hello" method="POST" action="">
    Hello
</form>

<script>
    document.forms.hello.action = 'j_security_check'+window.location.hash;
    alert(document.forms.hello.action);
</script>
