Clear value on reference field

[sowmyarajaram]

Hello All,

I have reference field by name field1 and 2 other fields by name field2 and field3. The values on field2, field3 are based on the reference field1. what I'm trying to achieve is if I have a value on field1 as xxxx, it sets field2, field3. later when I try to edit value on reference field1 to something else, i want the fields2, field3 to show no data on it (while i'm trying to change value on field1) 

Field1 = reference field

Field2, Field 3 = text field

Any help?

Hi,

Just checking to see if this is answered or you looking for some more information?

Are field2 and field3 pulling data that originates from the field1 record? I'm not a fan of duplicating data when you could just display those reference field values on the form via dot walking. What is the purpose of pulling the text in this way?

Hi there,

Are these fields also dependend on each other?

If not, you could simply set up a UI Policy. No code needed. UI Policy triggered on field 1, UI Policy Actions for your other fields with the checkbox "Clear the field value" checked. That;s all.

No scripting needed. No client scripts whatever, just UI Policy.

If my answer helped you in any way, please then mark it as helpful.

Kind regards,

Assuming you must be using onChange Client Script with getRefence() callback OR GlideAjax

Your onChange should look like this

It should clear field 2 and field 3 when Field1 is cleared out

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading) {
        return;
    }

if(newValue == ''){

g_form.clearValue('field2Name');

g_form.clearValue('field3Name');

}

// your logic here to set the values

}
