Comparing List Collector Values with another variable, if it matches show alert

[Nasir1]

Hi,

Sorry it might be a noob question but I have catalog item that has a list collector (employee_current_roles) which auto-populates user's roles with all the roles user is member of, I have another variable (role) on the form that is reference field and users can pick up any roles and log the request.

What I want to do is If any of the roles in list collector matches the value in referenced field I want a pop up to say User is already member of the role but I am not sure if what I am doing is correct, please help.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var urole = g_form.getValue('role');
    var gr = g_form.getValue('employee_current_roles'); //  getting the List Collector Variable value
    var ar = gr.split(','); // split the list collector by comma
    
    for (var i = 0; i < ar.length; i++); 

    if (ar.indexOf(urole) == -1) //if field values are the same then send alert
       { 
        alert('User is already Member of the Selected role');
        g_form.clearValue('role');
    }

}

Can you share screenshot of your script, the whole form.

Apologies mate honestly I can see now what I did wrong there, please take it as a noob mistake and will keep your feedback in mind for next time when I am marking correct Answer. I wish ServiceNow had an option to mark more than one correct answer and mark everyone who replied as champions :). 

Again apologies for the rookie mistake!!

Hi Nasir,

Instead of writing a client script better you need to exclude the roles which are there in list collector.

Reference qualifier:

javascript: "sys_idNOT IN"+current.variables.variable_name; //list collector variable name

Hope it helps

Thanks,
Murthy

Good Idea but I am using the same variable set in other categories on the same form, and requirement is to display the role for other categories as we are using those roles for employment types
