prevent enter key from submitting form

I'm trying to prevent default actions from occurring when the Enter key is pressed. I'm working in someone else's .NET form. I've found a couple of jquery options intended to defeat the Enter key form submission, but neither is working for me. Here's what I've tried:

$("input").keypress(function (evt) {
var charCode = evt.charCode || evt.keyCode;
if (charCode  == 13) { 
return false;
}
});

 
  $(document).ready(function() {
		$(document).keypress(function(e) {
			if(e.keyCode == 13) e.preventDefault();
		})
  });

Open in new window

Here you can see what I'm trying to defeat:

<input name="ctl00$ctl00$cntrlID_11078" type="text" value="" id="ctl00_ctl00_cntrlID_11078" onkeypress="if(typeof(CheckForFormSubmit)==&#39;function&#39;){ return CheckForFormSubmit(event);}" />

Open in new window

            var toRun = new Function($(e.target).data("keypress"));
            toRun();
        }
   });
});

Because the inline onkeypress will ALWAYS run first :(, we remove it, save it, break it, smash it, concatenate it to run it only if it's not the ENTER key pressed

Oops. I found an issue. In a form that also contains textareas, we can't enter line-breaks. Can the code be modified so that it allows the Enter key to work in a textarea?

Strike that. I see that this does exactly what I need:

var CheckForFormSubmit = function() {
     javascript:void(0);
}

Thanks!
