javascript - How to submit a form when the return key is pressed?

Question

Can someone please tell me how to submit an HTML form when the return key is pressed and if there are no buttons in the form? The submit button is not there. I am using a custom div instead of that.

Answer 1

To submit the form when the enter key is pressed create a javascript function along these lines.

function checkSubmit(e) {
   if(e && e.keyCode == 13) {
      document.forms[0].submit();
   }
}

Then add the event to whatever scope you need eg on the div tag:

<div onKeyPress="return checkSubmit(event)"/>

This is also the default behaviour of Internet Explorer 7 anyway though (probably earlier versions as well).
