有帮助：代码中在开头和结尾有 (*) 的行是我中断的行。
嘿伙计们，我对自定义 dojo 小部件有一个严重的问题。
我有以下代码（services.aspx）：
<asp:Content ID="Content2" ContentPlaceHolderID="formdojoRequirementsPlaceHolder"
runat="Server">
<script type="text/javascript">
dojo.require("js.Forms.ServiceDetails");
dojo.require("js.Forms.PendingServices");

dojo.addOnLoad(function() {
//LOCALIZATION
var glb_connections = [];
var ServiceDetailsTab = dijit.byId('ServiceDetails');
var PendingTaskTab = dijit.byId('PendingTask');
var PendingServicesTab = dijit.byId('PendingServices');
var CertificatesListTab = dijit.byId('CertificatesList');
var MessagesTab = dijit.byId('Messages');
if (ServiceDetailsTab) { ServiceDetailsTab.attr('title', glb_nlsStrings.ServiceTab) };
if (PendingTaskTab) { PendingTaskTab.attr('title', glb_nlsStrings.PendingTaskTab) };
if (PendingServicesTab) { PendingServicesTab.attr('title', glb_nlsStrings.PendingServicesTab) };
if (CertificatesListTab) { CertificatesListTab.attr('title', glb_nlsStrings.CertificatesTab) };
if (MessagesTab) { MessagesTab.attr('title', glb_nlsStrings.MessagesTab) };
ServiceDetailsTab = null;
PendingTaskTab = null;
PendingServicesTab = null;
CertificatesListTab = null;
MessagesTab = null;

var tab = queryObj['glb_currentTab'];
if (dojo.byId("ServiceDetailsWdj") != undefined) {
*djtServiceDetails.serviceTypeCode = serviceTypeCode;*
glb_connections.push(dojo.connect(djtPendingServices, "onServiceInstanceDeleted", function() {
*djtServiceDetails.onBack();*

*glb_connections.push(dojo.connect(djtServiceDetails, "onServiceCompleted", function() {

The 3 files : 1.dojo.require("js.Forms.ServiceDetails");
2.dojo.require("js.Forms.PendingServices");
3.dojo.require("js.Forms.CertificatesList");
是小部件。
该小部件是基于 MVC 构建的。
这里重要的是出现问题的视图部分，因此视图的代码如下：

好的，现在让我解释一下这个问题。
当我在 Internet Explorer 8 或 7 下运行此应用程序时，一切正常。但是当我尝试使用 IE9、Firefox 或 Chrome 打开它时，我收到一条错误消息，指出“未定义 djtServiceDetails”。
正如我从调试中了解到的，这是因为当文件被执行时，视图的postCreate部分没有被执行（postCreate 中的调试器永远找不到）
我有一个类似的页面，使用与上述相同的结构，适用于所有浏览器，我们找不到任何差异。
我希望你能告诉我一些可以帮助我解决这个问题的事情。
如果您需要更多信息，请告诉我。
先感谢您
