JSOM: Get SharePoint Site Users

This code snippet helps to retrieve the collection of user from the current site collection.

Supported SharePoint Version: Office 365 and SharePoint 2013 +.

function getsiteUsers() {
    var clientContext = SP.ClientContext.get_current();
    oUsers = clientContext.get_web().get_siteUsers();
    clientContext.load(oUsers);
    clientContext.executeQueryAsync(
        Function.createDelegate(this, function(){
    var usersInfo = '';
    var usersEnumerator = oUsers.getEnumerator();

    while (usersEnumerator.moveNext()) {
        var oUser= usersEnumerator.get_current();
        usersInfo += '\n' + 'User ID: '+oUser.get_id() + ',\t' +'Title : '+ oUser.get_title()+ ',\t'+'Login Name: '+ oUser.get_loginName();    }
    console.log(usersInfo.toString());
    }),
        Function.createDelegate(this, function(){console.log('failed');}));
}

Call the above method by using the below snippet. Because we have to ensure the SP.JS file loaded before calling the above method.

function injectMethod(){
       getsiteUsers();
}
ExecuteOrDelayUntilScriptLoaded(injectMethod, "sp.js");
