Adding a form element on the fly.

I used this code on my project yesterday and thought I'd share.

<script language="text/javascript">
    function addActionToForm() {
        // get the form to add the input element to
        var form = document.getElementById("noteForm");
        
        // Add a action input element
        var action = document.createElement("input");
        action.setAttribute("type", "hidden");
        action.setAttribute("name", "action");
        action.setAttribute("id", "action");
        action.setAttribute("value", "Save");
        
        form.appendChild(action);
        form.submit();
    }
</script>

This works great for me when I want to simulate a button named "action" being clicked, but I want to submit the form with JavaScript.

Hmmm, doesn't seem to work in IE5/Mac. Any tips?

Hi Matt,

Thanks for the nice explanation. I'm facing the same issue and applied this fix... this helped me partially but, not 100%

My case is: I have a web application which uses form-based authentication. when I deploy it on Jboss node it works great. i.e., when I access any of application resource (jsp) it takes me to login.jsp and when I enter credentials it takes me to main page (on success)

When I deploy this app on JBoss cluster... it is weird. App access takes me to login.jsp but, it don;t take me to main page on login; it is throwing an error (Invalid Login page...) If I refresh the page and re-enter the credentials then, it works fine.

I applied your fix... now, instead of showing me the error, it goes back to 'login.page'... but, as I entered correct credentials it shd take me to main page...

Any clue??

Thanks,
Suresh
