ReferenceError：未定义网站

Question

我正在为SharePoint 2013构建一个图像卷标器，并且出现此错误指向此行并且我不确定原因。我在学习html/js，所以我非常感谢所有的帮助。

这是代码返回错误

var oList = website.get_lists().getByTitle(bannerListName);  

还有更多它的路线，但是这是什么阻止它。

(function() 
{ 
/********************* User Defined Variables *************************************** 
**** Update the variables below to customize how the banner rotator works ***********/ 
var bannerListName = "Banner Rotator"; //the name of the list to pull the banner items from 
var interval = 7; //time to wait before showing the next picture (in seconds) 
var showPages = false; //change to false if you do not want to show the page numbers 

//if you know how to write CAML you can update this string 
//by default it looks for all items in the list, but you can change that here 
var query = '<View><Query><Where><Geq><FieldRef Name=\'ID\'/><Value Type=\'Number\'>1</Value></Geq></Where></Query><RowLimit>10</RowLimit></View>'; 
/***********************************************************************************/ 

//global variables 
var index = 0; 
var bannerList = []; 

$(document).ready(function() 
{ 
     // make sure the SharePoint script file 'sp.js' is loaded before code runs 
     SP.SOD.executeFunc('sp.js', 'SP.ClientContext',start); 
         }); 

function start() 
{ 
    ctx = SP.ClientContext.get_current(); 
    this.site = ctx.get_site(); 
    this.website = ctx.get_web(); 
    var oList = website.get_lists().getByTitle(bannerListName); 
    var camlQuery = new SP.CamlQuery(); 
    camlQuery.set_viewXml(query); 
    this.collListItem = oList.getItems(camlQuery); 
    ctx.load(collListItem); 
    this.ctx.executeQueryAsync(onQuerySucceeded, onQueryFailed); 

} 

Answer 1

应该this.website并不仅仅是website

this.website = ctx.get_web(); //<-- you store it in this.website, not var website 
var oList = this.website.get_lists().getByTitle(bannerListName);
