How to restrict max length of characters, on a Catalog Form field, based on a dependent field ?

AbdurRahmanSnow · ‎02-26-2025

Good evening
On a Catalog form, based on Country is Thailand, then it should allow the below 3 Address line Fields to only take 70 characters/digit length.
How can I do this? Please guide.

Correct Answer

function onSubmit() {

//Type appropriate comment here, and begin script below

var country = g_form.getDisplayValue('country');

if (country == 'THAILAND') {

var add1 = g_form.getValue('Address1');

var add2 = g_form.getValue('Address2');

var add3 = g_form.getValue('Address3');

//alert('Address lengths: ' + add1.length + ', ' + add2.length + ', ' + add3.length);

if ((add1.length > 70) || (add2.length > 70) || (add3.length > 70)) {

alert('The maximum character limit for addresses in Thailand is 70.!');

return false;

}

return true;

}

Yes Sir, but it should only apply to Thailand country and not to other countries. How can we do it?

Then you need to use the onsubmit script and add this field count.

@AbdurRahmanSnow

since you said combination of all 3 should be max 70,

you can use onSubmit, get values from all 3 variables and check max length
OR

You can use single line text variable and give max_length=70 in variable attributes

If my response helped please mark it correct and close the thread so that it benefits future readers.
