我有一个在 SharePoint 上工作的 .aspx 文件。我们正在使用 IE11、jQuery 2.2.3、jQuery UI 1.11.4、Bootstrap 3.3.6 我们由第三方拥有这个系统大约三年，我们停止了业务。并且无法再联系。
它工作正常，直到几周前突然页面永远加载并显示此错误
SCRIPT5007：无法获取未定义或空引用的属性“toLowerCase”
我已经用 Google 搜索过，似乎脚本正在等待 ConfigurationCube.js 加载。但由于它没有加载，我认为它会永远等待。
/* handles the displaying of all outstanding items requiring approval*/
var TableCreated=0;
var app="";
var teamsArr = [];
var GlobalDivisionsArr = [];
$(document).ready(function(){
//check to see if the Configuration cube Obj Exists and wait until it does
var checkExist = setInterval(function() {
if (sessionStorage["ConfigurationCube"] != null) {
app = JSON.parse(sessionStorage.ConfigurationCube).AppURL;
/**CreateLookupSectionForEmployees("My Winners","Kaizen List","#ViewWinnersTable");**/
//Displayed using the configuration cube.js file
DisplayUserInformation();
popDD("kznSearchCategory",JSON.parse(sessionStorage.ConfigurationCube).ListOfCategories);
IntialPopulationOfApprovedKaizens("","Kaizen List","#kznSearchResultsTable");
//Initialize date range picker
/**$("#kznEditToDate").datepicker();*/
var CubeMin = (JSON.parse(sessionStorage.ConfigurationCube).SubmissionPeriod).split(" ")[0];
clearInterval(checkExist);
}
}, 500);
});
我也在 IE8、9、10、Edge 中尝试过。都不起作用。我们公司不允许使用 Chrome 或任何其他浏览器，所以我们需要让它在 IE 中运行。我目前的元标记是这样的。也尝试了各种方法，但没有奏效。

有没有人有类似的问题？任何想法表示赞赏..
单击错误时，它会指向 ConfigutationCube.js
//Tools for other pages
function compareStrings(a, b) {
// Assuming you want case-insensitive comparison
a = a.toLowerCase();
b = b.toLowerCase();
return (a < b) ? -1 : (a > b) ? 1 : 0;
}
来自 SearchKaizen.js 的脚本片段

$.when(GetKaizenPromise).done(function(KaizenSelectionData){
var EditButton = "";
var Results = KaizenSelectionData.d.results;
//Creates table structure and heading
var DataTableHtml = "";
var SetVotedBackground = "style='background-color:lightgreen;color:white;'";
var DivisionList = [];
var TeamList = [];
var YearList = [];
var DivisionCheck = [];
var TeamCheck = [];
if(Results.length > 0){
for(r=0;Results.length > r;r++){
TableCreated++;
var ResultsName = Results[r].Nominated_x0020_person;

}
YearList.sort();
YearList.reverse();
TeamList.sort(function(a, b) {

popDD("kznSearchYear",YearList);
popDDSearchWithDataAttr("kznSearchTeam",TeamList,TeamList);
DivisionList.unshift({"FullName": "All","ID":"All"}); //Add All option to division list
popDDVal("kznSearchDivision",DivisionList);
//adds items to DOM
$(ElementToAppend + " tbody").html(DataTableHtml);
//Create column match with returned results
if (Results.length>0){
$.fn.dataTable.ext.errMode = 'console';
$(ElementToAppend).DataTable({
"dom": 'ftipr',
"responsive": true
});
}
$("body").css("overflow","");
//removes overlayer and loading symbol
$("#OverlayFade").addClass("hidden");
$("#Timer").addClass("hidden");
});
}
这个脚本片段有 popDDVal，它看起来像 'DivisionList' 'TeamList' 'YearList' 返回 null。由于这是 null 它不能从加载覆盖层中断。
我能够将其缩小到这一部分。
TeamList.sort(function(a, b) {
return compareStrings(a.FullName, b.FullName);
});
DivisionList.sort(function(a, b) {
return compareStrings(a.FullName, b.FullName);
});
把它改成了这个，它起作用了。但显然排序没有正确排序，但至少它现在可以工作......
TeamList.sort();
DivisionList.sort();
