prevent submit form in textarea when enter key used

[Tracey]

Hi there

I have a form with various inputs (txt, checkbox, textarea, submits). My problem revolves around the textarea. If a user wants to add a double line between paragraphs by hitting the enter key twice, the form is submitted on the second enter. (this behaviour is present in both IE7 and Firefox)

could someone please tell me how i can stop this annoying behaviour? I have tried some scripts to disable the key, however the user still needs to be able to add these double lines and most scripts disable the action, eg

function handleEnter(field, event) {
		var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
		if (keyCode == 13) {
			return false;
		} 
		else
		  return true;
	}

I notice the textarea i am currently typing into here at tek-tips does not have this issue..

Cheers in advance

Ok cancel this question, it was caused by a function called onkeypress of the form which was enabling form post on enter within an input.

I adjusted the code, fyi here:

function enterkey(event){
if (document.layers)
  document.captureEvents(Event.KEYDOWN);
  document.onkeydown =
    function (evt) { 
      var keyCode = evt ? (evt.which ? evt.which : evt.keyCode) : event.keyCode;

//ADDED THIS BLOCK OF CODE	
        //set myEvent to browser compatible property
	if (!event){ var myEvent = window.event;}
	else{var myEvent = event;}
	//set targ to browser compatible target
	if (myEvent.target) targ = myEvent.target;
	else if (myEvent.srcElement) targ = myEvent.srcElement;

      if (keyCode == 13)   //13 = the code for pressing ENTER 
      {
        //ADDED CONDITION
        if (!targ.type == "textarea")
         document.forms[0].submit();
      }
    }
}
