Passing a Value Between two SAPUI5 Mobile App Pages

[Former Member]

Hi Guys,

I want to pass a Value from Page1 of my SAPUI5 Mobile App to Page2. But I don't know how can I pass it and then use this value on Page2 (in MVC Architecture). Please guide me in this regard.

Thanks and best regards.

Fahad.

Hi Fahad

Take a look at the following example

sapui5-static/test-resources/sap/m/internal/demo/DemoAppToDoList.html

Its a mobile application using MVC. It has 2 pages notes and details.

from notes.controller.js

showDetails : function(record) {
          if (!this._detailsView) {
                    this._detailsView = sap.ui.jsview("todolist.details");
          }
          this._detailsView.getController().show(record);

When the user drills into a line of noteList the function showDetails in the notes.controller is called.

This then calls the details.controller via the details.view and passes the current record.

A nicer solution is the one Andreas suggested to you earlier in another post, use the EventBus. It is available in the latest version, very easy to use, below is a simple example of using events to pass data. When navigating between pages you can use events, subscribe on one publish on another.

$.sap.require("sap.ui.core.EventBus");
var oBus = sap.ui.getCore().getEventBus();
var params = {param1: "helloWorld"};
show = function(sChannelId, sEventId, oData){
  alert(oData.param1);
};
 //to subscribe
oBus.subscribe("myChannel","goToDetailsPage", show);
//to publish data between pages
oBus.publish("myChannel","goToDetailsPage",params);

Cheers
