Description: A script that checks the number of characters in a form box, and if it exceeds the predetermined number,
cancels the form submission, and asks the surfer to reenter data.

Example:

In 50 chars or less, please type a short description of yourself:



Directions: Simply cut and paste the below code into the <body> section of your page. It contains a form with one textarea
box that is checked for max # of characters. You can change this # from the default 50 to another by changing "var maxlength"
below. You can add in more form elements into the form, as you would with any other form.

<script>
<!--

/*Form Characters check script credit-Website Abstraction (www.wsabstract.com) 200+ free JavaScripts here!
*/

function checkchars(cur){
//change max length to determine below
var maxlength=50
if (cur.chars.value.length>maxlength){
alert("Please restrain your input to 50 or less characters!")
return false
}
}
//-->
</script>

<form onsubmit="return checkchars(this)">
<strong>In 50 chars or less, please type a short description of yourself:</strong><br><textarea rows="5" cols="38" name="chars"></textarea>
<br><input type="submit" value="Submit!">
</form>

I wrote a more cross-browser script here:

<script type="text/javascript">
<!--
/*****************************

function getlength(x,y){
return x < y;
}
function textlen(x,y){
var thelength = x.value.length;
window.status = thelength + " of " + y + " maximum characters.";
}

function maxtext(x,y){
var tempstr = x.value;
if(tempstr.length > y){
x.value = tempstr.substring(0,y);
alert("Please limit your entry to " + y + " characters or less.");
}
textlen(x,y);
}

</script>
