javascript thread: RE: Help with using OnKeyPress() to limit text insid a <textarea> box
If you can use the TextRange object from IE, try this:
<body>
<textarea id="txtArea">This is my Text Area</textarea>
</body>
<script>
var oTextRange = txtArea.createTextRange()
alert(oTextRange.text.length)
</script>

Subject: [javascript] Help with using OnKeyPress() to limit text inside
a <textarea> box
I want the Javascript to limit the characters in my textarea box to only
255 characters. This is the code I have below, but I can get it to work.
Could someone help me out or tell me what I am doing wrong. Thanks.
********
Req. Documents/Education: (255 characters max)<br>
<textarea cols="80" rows="4" name="qualifications" maxlength="255"
onkeypress="ueditkeypressed(this)"></textarea>
<script language="JavaScript">
function uEditKeyPressed(poField)
if (poField.type=="textarea")
{
if (poField.maxlength==0)
{
poField.maxlength=poField.rows*poField.cols;
}
if (poField.value.length>=poField.maxlength)
{
window.event.returnValue = false;
}
else
{
window.event.returnValue = true;
}
}
</script>
