Assuming a "word" is any sequence of non-whitespace characters surrounded
by whitespace, the following will count the words in a text area:

<form>
<textarea name="myTextare a"></textarea>
<input type="button" name="myButton" value="Count words"
onclick="countW ords(this.form. myTextarea.valu e);">
</form>
<script type="text/javascript">
function countWords(s) {
var words = s.split(/\s+/);
alert(words.len gth);
}
</script>

For preventing entry of more then 256 characters, you can use the
following. Be aware you should provide server-side validation as well,
since the client-side prevention shown below can easily be circumvented:

<textarea name="myTextare a" onkeydown="retu rn maxChars(this,
256);"></textarea>
<script type="text/javascript">
function maxChars(ta, count) {
return (ta.value.lengt h < count);
}
</script>
