How to apply onLoad field style using client script?

[saint]

Hi Experts,

I'm trying to apply backgroundColor to one of my custom field using OnLoad CS. I tried fetching the control of field as well as element, but the style is not getting applied, can someone please share a sample code of any client script they have created for the same use case.

@saint  - is it a reference field?

Hi,

function onLoad() {
var displayControl = g_form.getControl('sys_display.incident.company'); 
g_form.getReference('company', callBack);  
}
    function callBack(ref) {
        if (ref.u_global_corporate_network_firm === 'true') {
            displayControl.style.background = 'red';
        } 
		else {
            displayControl.style.background = '';
        }
    }
}

Thanks,

Rahul Kumar
