Show hide field based on checkbox help

[Steve42]

I am frustrated with a script.  I want to show hide a field based on a checkbox.  I thought I had it working then it does not.(I'm new to some of this part of SNow)

What I have is a form with 3 checkboxes with fields under them that I need to do the same thing to. 
one example is
Field: Notification  type (checkbox)  
Field Notification_info   type(string)

I have tried a client script, a UI Policy and nothing seems to work. 

Logic i'm using:
when the form loads check
if the Notification Checkbox is checked, 
     then show  Notification Info field,
else 
     hide the notification field. 

The code I'm using:

function onCondition() {
var notifications = g_form.getValue('u_cr_notifications_t_f');
if(notifications == true){
	g_form.setDisplay('u_notification_info', true);
} else {
	g_form.setDisplay('u_notofication_info', false);
}
	
}

I believe the code is good, as it's just a simple If statement based on the value of notifications which if it's checked should be true and if unchecked should be false.

I don't know which is better a UI policy, a client script, a business rule (I doubt a business rule).

Could someone offer some sound advice as to what I can do to get this working.

Hello,

Is "u_notification_info" a mandatory field ?

If yes , 

then make it non-mandatory before hiding it .

function onCondition() {
var notifications = g_form.getValue('u_cr_notifications_t_f');
if(notifications == true){
        g_form.setMandatory('u_notofication_info', false);
	g_form.setDisplay('u_notification_info', true);
} else {
        g_form.setMandatory('u_notofication_info', false);
	g_form.setDisplay('u_notofication_info', false);
}
	
}

Hi Steve,

I think you should try it with UI Policy. No need to write script.

First set "when to run" condition as: Notification --> is --> true

Then in "UI Policy Action" select the field to make it visible as: Field name=Notification info

and "Visible=true"(screen shot is given below).

Please check it with UI Policy and let me know whether it is working or not.

Where can I find an example on how to do that?

I have edited that reply. Please check.

Onkar, that was the trick, once I read through the form on what it was doing much easier to do that on this field. 

Many thanks

Stephen
