i wish to count number of characters in textarea box during typing in and
display it somewhere in html page. so the number will increase during
writing.

is it possible to do it by javascript?

Thanks a lot.

create an event for the onchange value of the textarea, get the value of the
textarea and then count the chars.

Use the onkeyup instead, and after onkeyup you check the character
count. onchange will only fire *after* the textarea has lost focus.

<html>
<head>
<title>count.htm</title>
<script type="text/javascript">
function count(that) {
window.status = that.value.length;
}
</script>
</head>
<body>
<form>
<textarea name="text" cols="50" rows="10" onkeyup="count(this)"></textarea>
</form>
</body>
</html>

Why the status bar? That will utltimately fail in Mozilla based browsers
that have the ability to script the status bar disabled.


And please fix your OE so that it does not quote signatures.

Not at all !
use : onkeyup
of the textarea, get the value of the
textarea and then count the chars.
Click to expand...

<textarea
onkeyup="document.getElementById('count').innerHTML=this.value.length;">
</textarea>
<p id="count">
