Learn to use JavaScript to limit and count a text field in your HTML based forms. Show the user how many characters are remaining that they can type into that field. It will limit the amount they can type in real time also. <html> <head> <script> var maxAmount = 250; function textCounter(textField, showCountField) { if (textField.value.length > maxAmount) { textField.value = textField.value.substring(0, maxAmount); } else { showCountField.value = maxAmount - textField.value.length; } } </script> </head> <body> <form> <textarea name="ta" rows="6" style="width:340px;" onKeyDown="textCounter(this.form.ta,this.form.countDisplay);" onKeyUp="textCounter(this.form.ta,this.form.countDisplay);"></textarea> <br> <input readonly type="text" name="countDisplay" size="3" maxlength="3" value="250"> Characters Remaining </form> </body> </html>
