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

Nasir1 · ‎08-03-2022

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');
    }

}

That's strange issue,

Can you try adding below alert to see what values those variables are storing:

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

	if (gr.indexOf(urole) > -1) //if field values are the same then send alert
	{ 
                alert("gr value :"+gr+" urole : "+urole);
		alert('User is already Member of the Selected role');
	}

}

with new alert you might understand the exact issue else show me the alert data you are getting so that I can help you further.

Let me know if you have any further queries.

Hey Mohit,

Sorry mate still not working, it wont even trigger the alert even though role selected is one of roles in list collector.

Mohith Devatte · ‎08-03-2022

okay seems weird can you try this

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 spt = gr.toString().split(',');
 
    if (spt.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');
    }

}
