sapui5演练step19重用对象问题
提问于 2019-04-17 00:11:11
根据文档，我构建了自己的对象，我想在对话框控制器nestedviewcontroller.controller.js中重用
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/m/MessageToast",
"sap.ui.demo.walkthrough.controller.Dialog"
], function (Controller, MessageToast, Fragment,Dialog) {
"use strict";
return
Controller.extend("sap.ui.demo.walkthrough.controller.NestedController",
{
...,
onOpenDialog : function () {
// set dialog
var oView = this.getView();
var myDialog = new Dialog(oView);
myDialog.open();
},
onCloseDialog : function () {
this.byId("Dialog").close();
}
});
});
错误消息：未捕获（在promise中）错误：无法从resources / sap.ui.demo.walkthrough.controller.Dialog.js加载sap.ui.demo.walkthrough.controller.Dialog.js：404 - 资源可能进入代码在这里找不到！

：未捕获的TypeError：对话框不是f.onOpenDialog的构造函数（NestedController.controller.js？eval：22）
sap.ui.define([
"sap/ui/base/ManagedObject",
"sap/ui/core/Fragment"
], function (ManagedObject, Fragment) {
"use strict";
return ManagedObject.extend("sap.ui.demo.walkthrough.controller.Dialog", {
constructor : function Dialog(oView) {
this._oView = oView;
},
exit : function () {
delete this._oView;
},
open : function () {
var oView = this._oView;
// create dialog lazily
if (!oView.byId("Dialog")) {
var oFragmentController = {
onCloseDialog : function () {
oView.byId("Dialog").close();
}
};
// load asynchronous XML fragment
Fragment.load({
id: oView.getId(),
name: "sap.ui.demo.walkthrough.view.Dialog",
controller: oFragmentController
}).then(function (oDialog) {
// connect dialog to the root view of this component (models, lifecycle)
oView.addDependent(oDialog);
oDialog.open();
});
} else {
oView.byId("Dialog").open();
}
}
});
});
