How to disable submitting a form when I press on the enter key?

I have a button in my form, the purpose is not to submit the form. When I press "enter" key, it behaves as if I submitted the form. I'd like the enter key to act as if I clicked a certain button which means it will call my custom function rather than submit the form. How can I do that? Thanks.

Hi Leandro,

Try something like this:

document.getElementById("YOURFORMNAMEHERE").onkeypress = function(e) {
  var key = e.charCode || e.keyCode || 0;     
  if (key == 13) {
    e.preventDefault();
  }
}

This will stop the enter key from submit. If you have a custom function you would like to trigger in there, you would have to put it after the preventDefault().
