Is there a way to limit the number of characters in a TextArea? For example this message box I am typing in... Is there a way to limit it so I cannot type any more characters?

Thanks!

Hmmm... not as far as I know. It's more an HTML issue than anything to do with FMP though.

You can use field validation to do it: the user will get a warining after submitting the form that they've typed too much, but that might not be what you want either.

Perhaps somebody will have some Java code to do it!

There's an excellent javascript (free use too!!) from Ronnie Moore> It even has a counter that tell you how many characters are left.

<!-- TWO STEPS TO INSTALL LIMIT TEXTAREA:

1. Copy the coding into the HEAD of your HTML document

2. Add the last code into the BODY of your HTML document -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->

<HEAD>

<SCRIPT LANGUAGE="JavaScript">

<!-- Original: Ronnie T. Moore -->

<!-- Web Site: The JavaScript Source -->

<!-- Dynamic 'fix' by: Nannette Thacker -->

<!-- Web Site: http://www.shiningstar.net -->

<!-- This script and many more are available free online at -->

<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin

function textCounter(field, countfield, maxlimit) {

if (field.value.length > maxlimit) // if too long...trim it!

field.value = field.value.substring(0, maxlimit);

// otherwise, update 'characters left' counter

else

countfield.value = maxlimit - field.value.length;

}

// End -->

</script>

</HEAD>

<!-- STEP TWO: Copy this code into the BODY of your HTML document -->

<BODY>

<!-- textCounter() parameters are: text field, the count field, max length -->

<center>

<form name=myform action="YOUR-SCRIPT.CGI">

<font size="1" face="arial, helvetica, sans-serif"> ( You may enter up to 125 characters. )<br>

<textarea name=message wrap=physical cols=28 rows=4 onKeyDown="textCounter(this.form.message,this.form.remLen,125);" onKeyUp="textCounter(this.form.message,this.form.remLen,125);"></textarea>

<br>

<input readonly type=text name=remLen size=3 maxlength=3 value="125"> characters left</font>

</form>

</center>

<p><center>

<font face="arial, helvetica" SIZE="-2">Free JavaScripts provided<br>
