How to retrieve View outside the controller - Openui5

Question

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

Answer 1

When I create a view i set a id

var theView=sap.ui.xmlview("OperationDetail, "<name of view>");

then i retrieve it by id

var theView = sap.ui.core.Core().byId("OperationDetail");
var myPage=theView.byId("pageOperation");

Answer 2

varRequired = sap.ui.getCore().byId("<name of view>");

this keyword refers to only the particular controller where as sap.ui.getCore() refers to the project views.

Answer 3

You can instantiate another view using:

var view = sap.ui.jsview("<name of view>");

If you´re using different view types you can choose the necessary function from here.

To avoid multiple instantiation you could do something like this:

var view = sap.ui.getCore().byId("id");

if (view === undefined) {
    view = sap.ui.jsview("id", "<name of view>");
}

See this for more details regarding view definition/instantiation and IDs.
