Question

我在SharePoint上有一个.aspx文件。我们正在使用IE11，jQuery 2.2.3，jQuery UI 1.11.4，Bootstrap 3.3.6 我们由第三方使用了该系统大约三年，我们停止了业务。而且无法联系了。

一切正常，直到几周前突然页面永久加载并显示此错误

SCRIPT5007：无法获取未定义或空引用的属性“ toLowerCase”

我已经使用Google搜索，似乎脚本正在等待加载ConfigurationCube.js。但是由于它没有加载，所以我认为它一直在等待。

/* 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。都无法正常工作。我们公司不允许使用Chrome或任何其他浏览器，因此我们需要在IE中启用它。我当前的meta标签就是这样。还尝试了各种方法，但是没有用。

<meta http-equiv="x-ua-compatible" content="IE=edge; charset=UTF-8">

有人有任何类似的问题吗？任何想法都值得赞赏。.

单击错误时，它会定向到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;
}

SearchKaizen.js中的脚本片段

function IntialPopulationOfApprovedKaizens(HeadingTitle,ListName,ElementToAppend){

//Get all current data from lists

        TeamList.sort(function(a, b) {

         });

        DivisionList.sort(function(a, b) {

        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"); 
});
}

此脚本片段具有popDDVal，并且看起来像'DivisionList''TeamList''YearList'返回null。由于此属性为null，因此无法脱离加载层。

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);
});

将其更改为此，并且它起作用了。但是显然排序没有正确排序，但至少现在可以正常工作...

TeamList.sort();
DivisionList.sort();

Answer 1

不是传递匿名函数，而是传递函数名称：

TeamList.sort（compareStrings）;

或

DivisionList.sort（compareStrings）;
