How do I pass a JSON object from one controller to another(/view to view)? - sapui5

Question

I want to pass a JSON object from one controller to another. How do I do that?
Or can I pass a oModel to the other view? If so how do I do that?
Thanks

Answer 1

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 then be accessed from any other controller/view in your application context

Answer 2

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

Answer 3

To add to Qualiture's answer:
If you wanted to attach a specific model to a specific view, which your question sounds like a little, you can do just that by going:
view.setModel(oModel);

Answer 4

yes,you can pass string,object and Array from one view to another through the 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);
}
