How to retrieve View outside the controller - Openui5
提问by padibro
If I use this.getView()inside the controller of a view I can retrieve it without problems.
How can I retrieve the view if I am outside the controller (e. g. in controller of another view)?
如果我this.getView()在视图的控制器内部使用，我可以毫无问题地检索它。如果我在控制器之外（例如在另一个视图的控制器中），我如何检索视图？
I try sap.ui.core.Core().byId("<name of view>")but it returns undefined.
我尝试sap.ui.core.Core().byId("<name of view>")但它返回undefined。

You can instantiate another view using:
您可以使用以下方法实例化另一个视图：
var view = sap.ui.jsview("<name of view>");
If you′re using different view types you can choose the necessary function from here.
如果您使用不同的视图类型，您可以从这里选择必要的功能。
To avoid multiple instantiation you could do something like this:
为了避免多次实例化，您可以执行以下操作：
var view = sap.ui.getCore().byId("id");
if (view === undefined) {
view = sap.ui.jsview("id", "<name of view>");
}
See thisfor more details regarding view definition/instantiation and IDs.
见这对有关视图定义/实例和ID的更多细节。

When I create a view i set a id
当我创建一个视图时，我设置了一个 id
var theView=sap.ui.xmlview("OperationDetail, "<name of view>");
then i retrieve it by id
然后我通过 id 检索它
var theView = sap.ui.core.Core().byId("OperationDetail");
var myPage=theView.byId("pageOperation");

varRequired = sap.ui.getCore().byId("<name of view>");
thiskeyword refers to only the particular controller where as sap.ui.getCore()refers to the project views.
this关键字仅指特定控制器，其中 assap.ui.getCore()指的是项目视图。
