Set variable ReadOnly when Multi Row Variable Set not empty

[SamuelChang]

Hi all,

I need some help or guidance on how to set a variable Read-Only when the Multi Row Variable Sets (MRVS) not empty i.e. once it populated at least one item.

Basically, once I added Report Name & Email the field outside of MRVS should be set to Read-Only

I've tried onLoad client script but it doesn't work quite right

function onLoad() {
	var mrvs = JSON.parse(g_form.getValue('report_name_and_email'));
	if(mrvs.length > 0) {
		g_form.setReadOnly('add_or_remove', true);
	}
}

Is there something else that I missed?

Thank you in advance!

Thank you for your help but it doesn't seem to work on my my PDI is there something I missed?

1. Multiline text

2. Custom variable

3. Widget

4. Client script

I'm pretty sure I did everything

First of all, are you getting mrvs value in your hidden variable?

Try below in client script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading) {
        // Do nothing if the form is loading
        return;
    }

    if (newValue === ' ' ) {
        g_form.setReadOnly('report_email', false);
    } else {
        g_form.setReadOnly('report_email', true);
    }
}

How can I check if I'm getting mrvs value? Like a log somewhere?

Here is the updated client script per your suggestion

Before adding anything

After select Add selection then add item into mrvs

The "Report and email" still not set to Read Only

Same thing on Service Portal

MRVS value should be populated in your hidden variable. For testing, make sure hidden variable is visible on the form

It does not populate in my hidden variables
