尝试使用JSOM Sharepoint 2013创建发布页面并更改页面布局

Question

您好我正在尝试使用JSOM Sharepoint 2013创建发布页面并更改页面布局。我的代码运行没有错误，但不会更改页面布局或任何其他页面字段，例如'页面标题'

这是我的代码

'use strict';

var context = new SP.ClientContext('/sites/poc');
//var user = context.get_web().get_currentUser();

// Variables used in various callbacks 

var web;
var pubWeb;
var pageInfo;
var newPage;
var listItem;
//var hostWebUrl = decodeURIComponent(manageQueryStringParameter('SPHostUrl'));
//var appWebUrl = decodeURIComponent(manageQueryStringParameter('SPAppWebUrl'));

// This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function () {

    web = context.get_web();
    var user = context.get_web().get_currentUser();
    $('#CreatePage').click(function () { createPage(); });
});

function createPage() {
    context.load(web);
    context.executeQueryAsync(

        // Success callback after loading the App Web. 
        // We first want to get the host web, and cast it as a PublishingWeb. 
        function () {
            var hostUrl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
            var hostcontext = new SP.AppContextSite(context, hostUrl);
            web = hostcontext.get_web();

            pubWeb = SP.Publishing.PublishingWeb.getPublishingWeb(context, web);
            context.load(web);
            context.load(pubWeb);
            context.executeQueryAsync(

                // Success callback after getting the host Web as a PublishingWeb. 
                // We now want to add a new Publishing Page. 
                function () {
                    pageInfo = new SP.Publishing.PublishingPageInformation();
                    newPage = pubWeb.addPublishingPage(pageInfo);
                    context.load(newPage);
                    context.executeQueryAsync(
                        function () {

                            // Success callback after adding a new Publishing Page. 
                            // We want to get the actual list item that is represented by the Publishing Page. 
                            listItem = newPage.get_listItem();
                            context.load(listItem);
