Preventing form submission when Enter is pressed [duplicate]

Answer 1

If you don't want to edit the onsubmit event of the form, you can do it like this.
Add this to the text input:

onKeyPress="return noEnter(event)"

And this to the header:

    function noEnter(e)
    {
        var key;
        // firefox vs. ie
        (window.event) ? key = window.event.keyCode : key = e.which;
        (key == 13) ? return false : return true;
    }

easier to pull of with jquery.
