Disabling enter key for form

Question

I have been trying to disable the Enter key on my form. The code that I have is shown below. For some reason the enter key is still triggering the submit. The code is in my head section and seems to be correct from other sources.

disableEnterKey: function disableEnterKey(e){
        var key;      
        if(window.event)
            key = window.event.keyCode; //IE
        else
            key = e.which; //firefox      

        return (key != 13);
    },

Answer 1

if you use jQuery, its quite simple. Here you go

$(document).keypress(
  function(event){
    if (event.which == '13') {
      event.preventDefault();
    }
});
