Typeerror Controller.extend ist keine Funktion

Question

Wenn mein Projekt läuft, erhalte ich:

Error: failed to load 'stock/controller/plant.controller.js' from ./controller/plant.controller.js: TypeError: Controller.extend is not a function

Bitte, lassen Sie mich wissen, wie es zu beheben.

plant.controller.js

sap.ui.define([ 
    "sap/ui/core/mvc/Controller", 
    "jquery.sap.global", 
    "stock/Formatter", 
    "sap/ui/core/routing/History", 
    "sap/ui/model/json/JSONModel" 
], function (jQuery, Formatter, Controller, History, JSONModel) { 
    "use strict"; 

    var TableController = Controller.extend("stock.controller.plant", { 
     onInit: function() { 
      var oModel = new JSONModel(jQuery.sap.getModulePath("sap.ui.demo.mock", "/products.json")); 
      this.getView().setModel(oModel); 
     }, 

     getRouter : function() { 
      return sap.ui.core.UIComponent.getRouterFor(this); 
     }, 

     onNavBack: function (oEvent) { 
      var oHistory = History.getInstance(); 
      var sPreviousHash = oHistory.getPreviousHash(); 
      if (sPreviousHash !== undefined) { 
       window.history.go(-1); 
      } else { 
       this.getRouter().navTo("input", {}, true /*no history*/); 
      } 
     } 
    }); 
    return TableController; 
}); 

Component.js

sap.ui.define([ 
    "sap/ui/core/UIComponent", 
    "sap/ui/core/mvc/XMLView", 
    "sap/ui/model/json/JSONModel" 
], function(UIComponent, JSONModel, XMLView) { 
    "use strict"; 

    var Component = UIComponent.extend("stock.Component", { 
     metadata: { 
      manifest: "json", 
      getTable: function() { 
       return this._rootView.getContent()[0]; 
      } 
     }, 
     publicMethods: [ 
      "getTable" 
     ], 
     dependencies: { 
      libs: [ 
       "sap.m", 
       "sap.ui.layout" 
      ] 
     }, 
     rootView: "stock.view.input", 
     config: { 
      sample: { 
       files: [ 
        "view.input.view.xml", 
        "controller.main.controller.js", 
        "Formatter.js" 
       ], 
       description : "In this example assisted input is provided with table-like suggestions where several columns can display more details." 
      } 
     }, 

     init : function() { 
      UIComponent.prototype.init.apply(this, arguments); 
      this.getRouter().initialize(); 
     } 
    }); 

    Component.prototype.createContent = function() { 
     this._rootView = sap.ui.xmlview({ viewName : "stock.view.plant" }); 
     return this._rootView; 
    }; 

    return Component; 
});

Sie übersehen die Reihenfolge der Deklarationsdateien. In Ihrem Beispiel verwenden Sie eine "stock/Formatter" -Datei als "Controller", was offensichtlich falsch ist. Nachfolgend finden Sie eine richtige Reihenfolge:

sap.ui.define([ 
     'sap/ui/core/mvc/Controller', 
     'jquery.sap.global', 
     'stock/Formatter', 
     'sap/ui/core/routing/History', 
     'sap/ui/model/json/JSONModel' 
    ], function (Controller, jQuery, Formatter, History,JSONModel) { 
});
