limit characters in scrolling text box

phentalmyst · May 10, 2001

hey folks,

i was just wondering if there's a way to limit the amount of characters in a scrolling text box. i know in a single line box u just use maxlength, but that doesnt work in a scrolling one.

any help will be greatly appreciated!

thanks

This code limits the textarea to 20 characters...

Code:

=============================================================================================
<html>
<head>
<title></title>

<script language=&quot;JavaScript&quot;>
var txtAreaChars = 0;
var notLimited = true;
var txtMax
var firstBit = &quot;&quot;;
function countArea()
{
 txtMax  = document.getElementById(&quot;txtArea&quot;).innerHTML;
	if (txtAreaChars < 20)
	{
		txtAreaChars+= 1;
		
	}
	else 
	{
		if (txtMax.length < 20)
		{
			notLimited = true;
			txtAreaChars = txtMax.length + 1;
		}
		else
			notLimited = false;
	}
}
</script>
</head>
<body>
<textarea id=&quot;txtArea&quot; rows=5 cols=40 onKeyPress=&quot;countArea(); return notLimited&quot;>

</textarea>
</body>
</html>
