Disable Enter key submission on every form. 2

j4606 · Feb 2, 2006

I am working on a few forms that need to have the enter button disabled. With JavaScript I can acheieve this. The easiest example I found for disableing submission of a form when the enter button is pressed is given below.

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL unfurl="true"]http://www.w3.org/TR/html4/strict.dtd">[/URL]

<html>
<head>
<title>new document</title>

<script type="text/javascript">
function noenter() {
  return !(window.event && window.event.keyCode == 13); }
</script>

<style type="text/css">

</style>

</head>

<body>
<form name="f">

  <input type="text" name="t1" value="" onkeypress="return noenter()" /><br />
  <input type="text" name="t2" value="" onkeypress="return noenter()" /><br />
  <input type="text" name="t3" value="" onkeypress="return noenter()" /><br />
  <input type="text" name="t4" value="" onkeypress="return noenter()" /><br />
  <input type="text" name="t5" value="" onkeypress="return noenter()" /><br />
  <input type="text" name="t6" value="" onkeypress="return noenter()" /><br />
  <input type="submit" name="s" />
</form>
</body>

</html>

But inserting the

Code:

onkeypress="return noenter()"

into every single individual text box in the site seems unnecessarily laborious...

Is there a way I can include JavaScript in CSS documents?
Can I make it so everyone one my text boxes on any form in the website has enter disabled through CSS, or a javascript include file with out having to add

Code:

onkeypress="return noenter()"

to every single text box?

Thanks again

I don't know the answer but my good friend Google does.

Have you tried just putting the onkeypress event in the FORM tag?

I don't know the answer to your specific question (can you put JS in CSS). I'm pretty sure the answer is 'no'.

Putting the event in the form tag works. It wouldn't be very time consuming to add the event to all form tags but I am still hoping there is a lazier way of achieving this. It is a fun problem to try to fix. I'll post if I find a way around this till then I'll just use the solution given.

Thanks

Well, you can write a standard JavaScript function and import it into all your files:

Code:

window.onload = disableEnter();
function disableEnter()
{
 var x = document.forms.length;
 for(var i=0; i<x; i++)
  document.forms[i].onkeypress = "return noenter();"
}

Well, this is untested, but it seems like it should work. Certainly something like this would work and it's no different than attaching a CSS file to every page. ...although it won't work for people with JavaScript disabled.

Thanks for the info. I'll try to get it working.
My .js file looks like this right now

Code:

window.onload = disableEnter;
function disableEnter()
{
	var x = document.forms.length;
	for(var i=0; i<x; ++i)
	{
		document.forms[i].onkeypress="return noenter()";
		alert(document.forms[i].value);
	}
}

function noenter() 
{
	return !(window.event && window.event.keyCode == 13); 
}

and my html

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL unfurl="true"]http://www.w3.org/TR/html4/strict.dtd">[/URL]

<html>
<head>
<title>new document</title>

<SCRIPT LANGUAGE="JavaScript" SRC="disableenter.js">
</SCRIPT>

<style type="text/css">

</style>

</head>

<body>
<form name="f">

  <input type="text" name="t1" value="" /><br />
  <input type="text" name="t2" value="" /><br />
  <input type="text" name="t3" value="" /><br />
  <input type="text" name="t4" value="" /><br />
  <input type="text" name="t5" value="" /><br />
  <input type="text" name="t6" value="" /><br />
  <input type="submit" name="s" />
</form>
</body>

</html>

Can't figure out where I'm going wrong. Anyway thanks for the help.

My bad.

Change:

Code:

document.forms[i].onkeypress="return noenter()";

to:

Code:

document.forms[i].onkeypress=noenter;

noenter() does the necessary "return false"
