Hi,
I am preparing an application in Ruby on Rails. For creating the user interface, i have used HtmlHttpRequest, everything is working fine, except that that the return keys are not working with forms.
Can anybody advice me how to enable the return keys so that a user can submit the form when the return key is pressed.

For example
<a href="javascript:document.signup_form.submit();"><img src="/images/sign-up.jpg" /></a>

this is the statement Im using for submitting the form.

Cay anybody help me ?

-Regards
Saurav

If you have a Submit button an Enter keypress in an INPUT element should submit the form (textareas of course note).

You can add an ONKEYPRESS event handler to the form, something like:

if ((event.charCode || event.keyCode) == 13)
document.getElementById('submit').click();

where 'submit' is the ID of your submit button. Dirty I know, but calling submit() on the form itself won't trigger the onsubmit event handler whereas a simulated click will!
