Limit Characters Entered in Other Textbox

Looking to limit the number of characters that can be entered in an Other Textbox? While we don't have this feature built in, it's something that can be accomplished with a little bit of custom JavaScript.

Check it out in an example survey!


Download a survey with this script to your account!

To set the max characters for all other write-in fields in the survey copy and paste the below JavaScript in your the HTML of your survey them. To do so go to Style tab and scroll to the bottom of the survey preview to access the link to the HTML/CSS Editor. Paste the JavaScript the bottom of the HTML code on the Custom HTML tab.

  $('.sg-input-text-other').attr('maxlength', 10);

To get a little more specific with the other textboxes you affect you can add a custom class name to your question, and add that to the target in the script like so, where 'set-length' is the class name added to the question's Layout settings. Then copy and paste the below code to a JavaScript action on the page.

   $('.set-length .sg-input-text-other').attr('maxlength', 10);
