Javascript IE未捕获引用错误：jQ未定义，但在Chrome中工作

我得到一份工作

Uncaught ReferenceError: jQ is not defined

在Internet Explorer中，某些选项卡未加载

但使用Chrome，它的效果非常好

我认为这是因为jquery的脚本顺序可能是错误的。这是我的

startpage.js中的内容



在函数
loadSubtables（）
中，我从
gridhandling.js
调用了一些函数：

function loadSubTables() {

    if (checkNull(curuserid) == "") {
        curuserid = _spPageContextInfo.userId;
    }

    loadGrid("AKG", "&$select=Id,Title,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$filter=Author eq " + curuserid + " or Projektleiter eq " + curuserid +"&$orderby=Id desc", "gridmy", cnMyEntries, cmMyEntries, true, false);
    loadGrid("AKG", "&$select=Id,Title,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$filter=AKGStatus eq 'Aktiv'&$orderby=Id desc&$top=9999", "gridactive", cnMyEntries, cmMyEntries, true, false);
    loadGrid("AKG", "&$select=Id,Title,archivFlag,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$orderby=Id desc&$top=9999", "gridall", cnAllEntries, cmAllEntries, true, false);          
}

function loadGrid(listname, query, divname, colnames, colmdodel,showSubGrid,subGridFunction) {

    jQ("#" + divname).jqGrid({

我得到的错误引用了
gridhandling.js
中的这一行：

function loadSubTables() {

    if (checkNull(curuserid) == "") {
        curuserid = _spPageContextInfo.userId;
    }

    loadGrid("AKG", "&$select=Id,Title,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$filter=Author eq " + curuserid + " or Projektleiter eq " + curuserid +"&$orderby=Id desc", "gridmy", cnMyEntries, cmMyEntries, true, false);
    loadGrid("AKG", "&$select=Id,Title,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$filter=AKGStatus eq 'Aktiv'&$orderby=Id desc&$top=9999", "gridactive", cnMyEntries, cmMyEntries, true, false);
    loadGrid("AKG", "&$select=Id,Title,archivFlag,Projektstichwort,SD_x002d_Nummer,AKGStatus,Created,Author/Title,Author/Department,Author/WorkPhone&$expand=Author&$orderby=Id desc&$top=9999", "gridall", cnAllEntries, cmAllEntries, true, false);          
}

function loadGrid(listname, query, divname, colnames, colmdodel,showSubGrid,subGridFunction) {

    jQ("#" + divname).jqGrid({

我检查了jQuery是否已加载，确实如此，但5个小时以来，我无法找出问题所在以及如何修复此错误。有时它不加载任何内容，只是说
jQ（#tabs”）.tabs（）；不是函数

有人能帮帮我吗？
“这就是我在startpage.js中的内容”-为什么在
*.js
文件中有标记？@Andreas对不起，标记是什么意思？
是标记。它不属于只包含JavaScript代码的JavaScript文件。IE的哪个版本？jQuery的2.x分支取消了对传统浏览器和过时浏览器的大量支持。@Rorymcrossan IE 11
