未捕获(承诺):错误无法实例化对象 new 丢失 [英] Uncaught (in promise): Error Cannot instantiate object new is missing

问题描述

我有一个控制器:

Menu.Controller.js:

Menu.Controller.js:

sap.ui.define([
       "sapit/ext/utils/BaseController",
       "sap/ui/model/json/JSONModel",
       "sap/ui/model/Sorter",
       "sap/ui/model/Filter",
       "sapit/nova/model/constants",
       "sapit/ nova /model/formatter",
       "sapit/ nova /util/Helper",
       "sapit/ nova /util/Validator",
       "sapit/ nova /util/ItemService"
     ], function(BaseController, JSONModel, Sorter, Filter, constants, formatter, Helper, Validator, ItemService) {
       "use strict";

       return BaseController.extend("sapit.nova.controller.Menu", {

             formatter: formatter,
             helper: new Helper(),
             itemService: new ItemService(),


             onInit: function() {
               this.fragmentProcess = sap.ui.xmlfragment("sapit.nova.view.fragment.Process", this);
               // attach events
               this.getRouter().attachRouteMatched(jQuery.proxy(this.onRouteMatched, this));
             },
             onRouteMatched: function(oEvent) {
                 var oPage = this.byId("menuProcessor");
                 var sRouteName = oEvent.getParameter("name");

                 if (sRouteName === "Menu") {
                   // show fragment
                   this.helper.clearFragment(oPage);
                   this.helper.showFragment(oPage, this.fragmentProcess);
                 }

我有相应的 xml 视图作为 Menu.view.xml:

I have the corresponding xml view as Menu.view.xml:

mvc:View controllerName="sapit.nova.controller.Menu" xmlns="sap.m" xmlns:mvc="sap.ui.core.mvc">
    <Page id="menuProcessor" title="{i18n>menuPageTitle}" showNavButton="false">

    </Page>
</mvc:View>

我的路由器配置是:

"routes": [{
    "pattern": "/admin",
    "name": "Main",
    "target": ["menu"]
  },

  "targets": {
    "menu": {
      "viewName": "Menu",
      "viewLevel": 1,
      "controlAggregation": "masterPages"
    }

问题是当我运行此应用程序时，控件将转到 menu.controller 的 onInit ()，但它不会转到 onRouteMatched，尽管它正在获取附加到此视图的路由器实例.

The problem is when I run this application control is going to onInit () of the menu.controller but it's not going to onRouteMatched although it's getting the instance of router attached to this view.

每次我运行这个应用程序时，我都会在进入 onInit() 后收到一个错误，其余的代码不起作用，视图也没有出现.

Every time i run this application i am getting an Error after entering the onInit() and rest of code doesn't work and view doesn't come up.

Uncaught (in promise) Error: Cannot instantiate object: "new" is missing!
    at constructor (sap-ui-core.js:640)
    at constructor (sap-ui-core.js:1601)
    at constructor (sap-ui-core.js:1571)
    at f (sap-ui-core.js:638)
    at f (sap-ui-core.js:284)
    at p (sap-ui-core.js:285)
    at _ (sap-ui-core.js:286)
    at Object.properties (sap-ui-core.js:286)
    at l (sap-ui-core.js:298)
    at B.getText (sap-ui-core.js:296)

你能在这方面给我建议吗.

Can you please suggest me in this regard.

谢谢！！

推荐答案

去掉 sap.ui.define 中的空格这可能是加载 Helper、Validator 和 ItemService 时的问题

Remove the spaces from sap.ui.define this might be a problem when loading Helper, Validator and ItemService

sap.ui.define([
        "sapit/ext/utils/BaseController",
        "sap/ui/model/json/JSONModel",
        "sap/ui/model/Sorter",
        "sap/ui/model/Filter",
        "sapit/nova/model/constants",
        "sapit/ nova /model/formatter",
        "sapit/ nova /util/Helper",
        "sapit/ nova /util/Validator",
        "sapit/ nova /util/ItemService"
    ],
