hey AJ,
unfortunately you are completely out of luck on this one as Text Area does not have a max length property associated with it. http://www.w3.org/TR/REC-html32.html
just kidding...this is a good idea (keep them coming) and pretty quick and easy to do...so...here's some code below to give you a validation method for WETextArea.
1) go to your Admin folder in webElements 2.1 and open up the WEValidator and replace its code with
// WEValidator 2.1 last revision March 8, 2007, JWiseman
Function (stringvar ElementName, stringvar Validate, stringvar Message)
stringvar output;
if validate > "" then
validate:= lowercase(validate);
if validate ="empty" then output :=
'if(isEmpty(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return;' +
if validate in ["numeric", "number"] then output :=
'if(isEmpty(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return false; ' +
'}' +
'if (!isNumeric(getform.' + ElementName + '.value)) ' +
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus(); ' +
'return false;' +
if validate in ["email", "e-mail", "email"] then output :=
'if(isEmpty(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return false; ' +
'}' +
'if (!isValidEmail(getform.' + ElementName + '.value)) ' +
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus(); ' +
'return false;' +
if validate = "date" then output :=
'if(isEmpty(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return false; ' +
'}' +
'if (!isDate(getform.' + ElementName + '.value)) ' +
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus(); ' +
'return false;' +
if validate = "integer" then output :=
'if(isEmpty(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return false; ' +
'}' +
'if (!isInteger(getform.' + ElementName + '.value)) ' +
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus(); ' +
'return false;' +
if validate in ["check", "checked", "select", "selected"] then output :=
'if(!isButtonChecked(getform.' + ElementName + '))' +Â
'{ ' +
'alert("' + Message + '"); ' +
'return; ' +
if validate[1 to 6] = "value=" then
(validate:= validate[7 to length(validate)];output :=
&#39;if(isCertainValue(getform.&#39; + ElementName + &#39;,"&#39;validate&#39;"))&#39; + 
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return;' +
if validate[1 to 7] = "length>" then
(validate:= validate[8 to length(validate)];output :=
&#39;if(isMaxLength(getform.&#39; + ElementName + &#39;,&#39;validate&#39;))&#39; +
'{ ' +
'alert("' + Message + '"); ' +
'getform.' + ElementName + '.focus();' +
'return;' +
"<!validator " + output  + "><!|||>"
) else "";
2) now open WEFunctionLibrary and replace its code with
// WEFunctionLibrary 2.1 last revision March 8, 2007, JWiseman
Function ()
// functions for select all, clear all, reverse all buttons and links
&#39;function selectAll(cbList,bSelect) {&#39; <br />&#39;for (var i=0; i<cbList.length; i+)&#39; +
'cbList.selected = cbList.checked = bSelect&#39; <br />&#39;}&#39; <br />
&#39;function reverseAll(cbList) {&#39; <br />&#39;for (var i=0; i<cbList.length; i+){&#39; +
'cbList.checked = !(cbList.checked);' +
'cbList.selected = !(cbList.selected)&#39; <br />&#39;}}&#39; <br />
// VALIDATION FUNCTIONS
// function for numeric (float) input validation
'function isNumeric(sText){' +
&#39;var ValidChars = "0123456789.";var IsNumber=true;var Char;&#39; <br />&#39;for (i = 0; i < sText.length && IsNumber == true; i+) &#39; +
'{Char = sText.charAt(i); ' +
'if (ValidChars.indexOf(Char) == -1) ' +
'{IsNumber = false;}}return IsNumber;Â ' +
+
// function for integer input validation
'function isInteger(sTextB){' +
&#39;var ValidCharsB = "0123456789";var IsNumberB=true;var CharB;&#39; <br />&#39;for (i = 0; i < sTextB.length && IsNumberB == true; i+) &#39; +
'{CharB = sTextB.charAt(i); ' +
'if (ValidCharsB.indexOf(CharB)
== -1) ' +
'{IsNumberB = false;}}return IsNumberB;Â ' +
+
// function for non-null input validation
'function isEmpty(aTextField) {' +
'if ((aTextField.value.length==0) ||' +
'(aTextField.value==null)) {' +
&#39;return true;}else {return false;}&#39; <br />&#39;}&#39; <br />Â
// function for email input validation
'function isValidEmail(str){' +
'return (str.indexOf(".") > 2) && (str.indexOf("@") > 0);&#39; <br />&#39;}&#39; <br />
// function for date input validation
'function isDate(str){' +
'var dateVar = new Date(str);' +
'if(isNaN(dateVar.valueOf()) ||' +
'(dateVar.valueOf() ==0))' +
'return false;' +
&#39;else {return true;}&#39; <br />&#39;}&#39;<br />
// function for radio button and checkbox validation
'function isButtonChecked(aSelection) {' +
&#39;var checkcount = -1;&#39; <br />&#39;for (var i=0; i < aSelection.length; i+) {&#39; +
'Â Â if (aSelection.checked) {checkcount = i; i = aSelection.length;}' +
'Â Â }' +
'if (checkcount > -1) return aSelection[checkcount].value;' +
&#39;else return false;&#39; <br />&#39;}&#39;<br />
// function for inappropriate value input validation
'function isCertainValue(aTextField, vTextField) {' +
'if (aTextField.value==vTextField){' +
&#39;return true;}else {return false;}&#39; <br />&#39;}&#39; <br />
// function for maximum input length validation
'function isMaxLength(aTextField, mLength) {' +
'if (aTextField.value.length>mLength){' +
'return true;}else {return false;}' +
3) do not add these to your repository quite yet as you'll want to test this to see if there's no nasty bugs or side affects.
4) in your WETextArea function you'll have a validation for maximum length, so your code will look something like
WETextArea ("tb", {?tb}, "1in", "2in", "", "length>16", "there are way too many characters here")
NOTE: this is for maximum length only and this will not do a minimum length at this time...should that need arise in the future i can create a validation for "length
