How to pass JSON object from one controller to another (/ view to view)?

I want to pass a JSON object from one controller to another. How to do it?

Or is it possible to pass oModel to another view? If so, how do you do it?

thank

If you store your data in a global model:

var oData  = <your JSON data>;
var oModel = new sap.ui.model.json.JSONModel(oData);
sap.ui.getCore().setModel(oModel);


it can be accessed from any other controller / view in the context of your application.

one solution is to use sap.ui.core.EventBus . Basically you can pass any object from one controller to another including JSONModel using subscribe and publish .

To add to Qualiture's answer:

If you want to attach a specific model to a specific view, which your question sounds a bit like, you can do so by going:

view.setModel(oModel);

yes, you can pass string, object and array from one view to another via navigation.

    enter code here
enter code here for controller
    handleLinkPress: function(oEvent) {
            try {

                var array = [];

                var obj = {

                    "Delivery": "80000095",
                    "DelvNo": "80000095",
                    "Date": "2018-01-04T00:00:00.000Z",
                    "Priority": "00",
                    "LoadDate": "2018-01-04T00:00:00.000Z",
                    "PickDate": "2018-01-04T00:00:00.000Z",
                    "ShippingPoint": "0001",
                    "Route": "",
                    "LoadingPoint": "01",
                    "ShipTo": "CUSTOMER",
                    "SoldTo": "CUSTOMER"
                };
                array.push(obj);
                if (obj !== null) {
                    sap.ui.core.UIComponent.getRouterFor(this).navTo("Route", {
                        RouteData: JSON.stringify(array)
                    });

                }

            } catch (e) {

                console.error("Error : " + e.message);
                sap.m.MessageBox.show(e.message, {
                    icon: sap.m.MessageBox.Icon.ERROR,
                    title: "Error",
                    actions: [sap.m.MessageBox.Action.OK],
                    defaultAction: sap.m.MessageBox.Action.OK,
                    styleClass: "sapUiSizeCompact",
                    contentWidth: "150px"

                });
            }

        }

Code for manifest.json
    {
    "pattern": "Route/{RouteData}",
    "name": "Route",
    "targetControl": "masterView",
    "viewId": "Route",
    "viewName": "Route"
    }

code for the controller where you get that Array which you want pass 

    handleCloseRoutePress: function(oEv) 
{

             var sRouteData=JSON.parse(oEv.getParameter("arguments").RouteData);


        }
