[2022_ServiceNow]

Hi everyone,

Is it possible to add the minimum characters required to the catalog field of variable type multi-line text?

Eg: I want a user to at-least write 30 characters before submitting.

Hi,

Yes you can validate the length of the variable while submitting the form.

1. Create a onSubmit catalog client script on your catalog item.

try below script

you can add alert or infomessage based on your requirement you can add.

function onSubmit() {

    var minLength = 30; //Define the length here
    var field1 = g_form.getControl('description'); //Replace description with your variable name
    if (field1.value.length < minLength) {
       // g_form.addInfoMessage('description should not be less than 30 characters');
        alert('Description should not be less than 30 characters');
        return false;
    }
}

Hope you it helps you.

Please Mark ✅ Correct/helpful if applicable, Thanks!!

Hi,

Thank you for the response.

This is working fine when I try it in the ServiceNow catalog.. but in the Service Portal, it's not working, I can submit the form with less than 30 characters also.

Hi,

No it will work in portal as well but you need to select UI type as All in Catalog client script.

Hi Priya,

Instead of writing a client script you can actually achieve just by using Variable validation regex.

Create a record in question_regex table and call it in variable. See below for your reference:

^(?=.*\d).{30,}$

Hope it helps.
