Question

I see on many sites that the enter key will submit a form but you could also click on the button to submit. Is there a trick to this? Or can a button have two different types of functions attached?

Answer 1

My dear there is nothing tricky. Just put the type of the button as submit and your will achieve what you are wanting. See This

After UPDATE

When there is a form tag in your html page, enter button always submit the form. If you have made your own button having type="button" even then you can submit form onclick it.

<input type="button" onclick="submitform();" value="Button">

and here is your javascript function

function submitform()
 {
   document.forms["myform"].submit();
 }

Hence your both cases can be achieved
