Table

[Ram012]

Create one list type field reference to user table when someone remove any values from the list or add any users to the list fields , then it will shows the
alert/pop up with the added/removed users list to the end - user use your own table ?

Client Script:

function onLoad() {
// Get the initial value of the watchers field
var initialWatchers = g_form.getValue('u_watchers');
}

function onSubmit() {
// Get the current value of the watchers field
var currentWatchers = g_form.getValue('u_watchers');

// Find the added and removed users
var addedUsers = [];
var removedUsers = [];
for (var i = 0; i < currentWatchers.length; i++) {
if (initialWatchers.indexOf(currentWatchers[i]) == -1) {
addedUsers.push(currentWatchers[i]);
}
}
for (var i = 0; i < initialWatchers.length; i++) {
if (currentWatchers.indexOf(initialWatchers[i]) == -1) {
removedUsers.push(initialWatchers[i]);
}
}

// Show the alert/pop up with the added/removed users
if (addedUsers.length > 0 || removedUsers.length > 0) {
var message = 'Watchers updated:';
if (addedUsers.length > 0) {
message += '\nAdded: ' + addedUsers.join(', ');
}
if (removedUsers.length > 0) {
message += '\nRemoved: ' + removedUsers.join(', ');
}
alert(message);
}
}

 Write the code using client script but not working.

I have modified the script for your reference.

var initialWatchers;

function onLoad() {
    // u_watchersフィールドの初期値を配列として取得
    initialWatchers = g_form.getValue('u_watchers').split(',');
}

function onSubmit() {
    // u_watchersフィールドの現在の値を配列として取得
    var currentWatchers = g_form.getValue('u_watchers').split(',');

    var addedUsers = [];
    var removedUsers = [];

    // 追加されたユーザーを検出
    currentWatchers.forEach(function(user) {
        if (initialWatchers.indexOf(user) == -1 && user) {
            addedUsers.push(user);
        }
    });

    // 削除されたユーザーを検出
    initialWatchers.forEach(function(user) {
        if (currentWatchers.indexOf(user) == -1 && user) {
            removedUsers.push(user);
        }
    });

    // 追加/削除されたユーザーを含むアラートを表示
    if (addedUsers.length > 0 || removedUsers.length > 0) {
        var message = 'ウォッチャーが更新されました:';
        if (addedUsers.length > 0) {
            message += '\n追加: ' + addedUsers.join(', ');
        }
        if (removedUsers.length > 0) {
            message += '\n削除: ' + removedUsers.join(', ');
        }
        alert(message);
    }

    return true; // フォームの送信を許可
}
