Remove user from group Javascript

Question

Hi I followed another thread but cannot get the following code to work. I changed Line 8 from web to oWeb, error seems to be around line 8/9

I'm trying to remove a user from a group.

    function removeUserFromGroup()
    {

    var clientContext = new SP.ClientContext.get_current();
    var oWeb = clientContext.get_web()
    var collGroup = oWeb.get_siteGroups();
    var oGroup = collGroup.getById(25); //Change 7 based on the group's id
    var oUser = oGroup.get_users();
    clientContext.load(oUser);
 8)   var user = oWeb.ensureUser('DOM1\jon');

 9)   oUser.removeByLoginName(user.get_loginName());   

    clientContext.executeQueryAsync(Function.createDelegate(this, onQuerySucceeded7), Function.createDelegate(this, onQueryFailed7));   

    }


    function onQuerySucceeded7(){
        alert('User Removed');
    }

    function onQueryFailed7() {
        alert('Failed');
    }

UPDATE

If I comment ensureUser ByLoginName lines it executes.

I've now change last two lines to the following and seems to work but I'd rather use Account 'domain\username'

var user = oWeb.ensureUser('Sharepoint Jon'); oUser.remove(user);

You are attempting to use a property that has not been loaded yet. Line 9 contains user.get_loginName(). Before you can use this, you need to load it first:

clientContext.load(user, 'Include(LoginName)');
clientContext.executeQueryAsync(function(){
    oUser.removeByLoginName(user.get_loginName());
    clientContext.executeQueryAsync(
        Function.createDelegate(this, onQuerySucceeded7),
        Function.createDelegate(this, onQueryFailed7)
    );
}, function(args) { alert(args.get_message()); } );
