Spell check extending words past textbox/area max size



In Chrome browser, spell check does not extend the size of a textarea or box when correcting misspelled words.

However, in Internet Explorer, which is used, spell check will extend the number of characters in a textarea or box passed the maximum when correcting misspelled words.

Error Messages

Not Applicable

Steps to Reproduce

  1. Put a maximum size on a textarea/box and then misspell some stuff up to the max.
  2. Right-click on the red squiggly underline misspelled words and fix them.

Root Cause

This behavior difference between browsers is expected.


Perform the following local-change:

Use the following function in the userworkform and executing it via runscript onchange/focus of the textarea to make sure that the number of characters does not exceed the maxlength even if it is accidentally set via spell-check:
window.trimTextArea = function(event){
var target =;
var len = parseInt(target.getAttribute("maxlength"), 10);

if(target.value.length > len) {
//alert('Maximum length exceeded: ' + len);
target.value = target.value.substr(0, len);
return false;
