Populate users with comma separated in a String field

[Lucky1]

Hi folks,

on the request form, there are 2 fields, "Requester" which is of type reference and "Users List" which is of type String. When i select a user in the requester then in the Users List field, his user ID should populate and the Requester field should get cleared. Another time if you select other user, then the Users List field should populate with that value too with comma separated. 

Note: The user which we have already selected should not populate again when we try to select him again. It should give alert like "you have already selected the user"

So for my above query, i am showing an example here:

If i select Abel Tuter in Requester field, then the Users List field should populate with Abel.Tuter, Now if you select Dean james then the Users List field should look like Abel.Tuter,Dean.Jones

Like this the Requester field should be cleared and the selected users should populate in the Users List field with comma separated. No duplicates should come. 

I tried with get Reference method, and i am able to populate Users List field with only one value. I think we have to use for loop and an array to store those selected values. 

Can some one please give me code for this above task

regards,

Lucky

My version:

Client script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var ajax = new GlideAjax('GetUserInfo');
    ajax.addParam('sysparm_name', 'getUserId');
    ajax.addParam('sysparm_user_id', newValue);
    ajax.getXMLAnswer(function(answer) {
        if (answer.length > 0) {
            var users = g_form.getValue('users_list');
            var usersList = users.split(',');
            if (!usersList.includes(answer)) {
                if (users.length > 0) {
                    users += ',';
                }
                users += answer;
                g_form.setValue('users_list', users);
            }
        }
    });
    g_form.setValue('requester', '');
}

Script include:

var GetUserInfo = Class.create();
GetUserInfo.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getUserId: function() {
        var userSysId = this.getParameter('sysparm_user_id');
        var grUser = new GlideRecord('sys_user');
        if (grUser.get(userSysId)) {
            return grUser.user_name;
        }
        return '';
    },
    type: 'GetUserInfo'
});

Execution output:

HI Hitoshi,

I tried with your code,

When i select Abel Tuter, the Users List field is populating with undefined,,Abel.Tuter, thats it. 

Please observe, it is taking two commas above

The Value of Requester is getting cleared but when i again select, Alene Rebeck then the Abel.Tuter is replaced with Alene.Rebeck

So my Users List field is now, undefined,Alene.Rebeck

Regards,

It may be the variable names. I've used "user_list" in my code. Following is a code using u_user_list.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var ajax = new GlideAjax('GetUserInfo');
    ajax.addParam('sysparm_name', 'getUserId');
    ajax.addParam('sysparm_user_id', newValue);
    ajax.getXMLAnswer(function(answer) {
        if (answer.length > 0) {
            var users = g_form.getValue('u_users_list');
            var usersList = users.split(',');
            if (!usersList.includes(answer)) {
                if (users.length > 0) {
                    users += ',';
                }
                users += answer;
                g_form.setValue('u_users_list', users);
            }
        }
    });
    g_form.setValue('requester', '');
}

Can you try below.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var getmembers = g_form.getValue("u_members");
    var existingList;
    if (getmembers != '') {
        existingList = getmembers;
    }

    var caller = g_form.getReference('u_select_the_members', getRequestedInfo);

    function getRequestedInfo(caller) {
        //   var existingList = g_form.getValue("u_members");
        var newList = [];
        if (existingList.length > 0) {
            newList = existingList.split(",");
            if (newList.indexOf(caller.name) < 0) {
                newList.push(caller.name);
                g_form.setValue("u_members", newList);
            } else
                g_form.addErrorMessage("you have already selected the user");
        } else
            g_form.setValue("u_members", caller.name);
    }
    g_form.setValue("requestor", "");

}
