How do I remove a Decoration via OnChange?

Shane J · ‎06-08-2018

What can I use to remove a decoration added via g_form.addDecoration in an onChange Client Script? g_form.removeDecoration isn't available.

So, turns out removeDecoration takes multiple parameters. I put this on my PDI and tried it out. I updated the removeDecoration to have three parameters;

g_form.removeDecoration('caller_id', 'icon-star', 'VIP');

function onChange(control, oldValue, newValue, isLoading) {
    var callerLabel = $('label.incident.caller_id');
    var callerField = $('sys_display.incident.caller_id');
    if (!callerLabel || !callerField) {
        return;
    }

    if (!newValue) {
        callerLabel.setStyle({
            backgroundImage: ""
        });
        callerField.setStyle({
            color: ""
        });
        return;
    }
    g_form.getReference('caller_id', function(caller) {
        var callerLabel = $('label.incident.caller_id').down('label');
        var callerField = $('sys_display.incident.caller_id');
        if (!callerLabel || !callerField)
            return;

        //check for VIP status
        if (caller.vip == 'true') {
            var bgPosition = "95% 55%";
            if (document.documentElement.getAttribute('data-doctype') == 'true')
                bgPosition = "5% 45%";

            //callerLabel.setStyle({backgroundImage: "url(images/icons/vip.gif)", backgroundRepeat: "no-repeat", backgroundPosition: bgPosition, paddingLeft: '5px', color: "#e34234" });
            callerLabel.setStyle({
                color: "#e34234"
            });
            callerField.setStyle({
                color: "#e34234"
            });
            g_form.addDecoration('caller_id', 'icon-star', 'VIP');
        } else {
            callerLabel.setStyle({
                backgroundImage: "",
                color: ""
            });
            callerField.setStyle({
                color: ""
            });
            //g_form.removeDecoration('caller_id');
			g_form.removeDecoration('caller_id', 'icon-star', 'VIP');
        }
    });
}

It should be available on both mobile/sp and desktop. Where is it unavailable?

I think you misread. I changed the VIP Client Script to use addDecoration instead. The problem is that if the Caller is changed to a non-VIP, the icon doesn't disappear.

Can you share your code? g_form.removeDecoration(...) should be available.

Also so this is on the standard UI or in the service portal?

Maybe I'm just using it incorrectly?
