Client Script to auto populate field based on another field not working

[Community Alums]

I want to display the 'parent' value in the 'project' field based on the budget. I tried a getReference and that kept returning the sys id. How do I return the value correctly using displayBox method or getDisplayValue?

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

    if (isLoading || newValue === '') {

        return;

    }

    var budget1 = g_form.getDisplayBox('parent').value;

g_form.setValue('project', budget1.parent);

Hi @Community Alums ,

Try this code and make sure the backend value of the fields are correct.

var budget1 = g_form.getDisplayValue('parent');
g_form.project = budget1;

Hi @Community Alums 

Please try with the script below.

function onChange(control, oldValue, newValue, isLoading) {

    var caller = g_form.getReference('caller_id', doAlert); // doAlert is our callback function

}

function doAlert(caller) { //reference is passed into callback as first arguments

  g_form.setValue('email',caller.email);

  g_form.setValue('phone',caller.mobile_phone);

  g_form.setValue('phone',caller.location);

}

Please change the variable name

@Community Alums Please update the client script as follows.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    var budget1 = g_form.getReference('budget', callback);
   
function callback(budget1){
g_form.setValue('project', budget1.parent);
}
}

This script returns the sys_id. I want the display value to show.
