        var currentContext = new SP.ClientContext.get_current();
        var currentWeb = currentContext.get_web();
        var todoTaskList = currentWeb.get_lists().getByTitle(ListName);
        var myQuery = new SP.CamlQuery();
        myQuery.set_viewXml('<View><Query><Where><Eq><FieldRef Name="Author" /> <Value Type="Integer"><UserID Type="Integer"/></Value></Eq></Where></Query></View>');
        myItems = todoTaskList.getItems(myQuery);

    function GetFail(sender, args) {


    function GetSuccess(sender, args) {
        var itemCount = myItems.get_count();
        if (itemCount == null || itemCount <= 0) {
            $('.ms-addnew').css('display', 'inline-block');
            $('#Ribbon\\.ListItem\\.New').css('display', 'inline-block');
