following problem

I got 2 functions

This is my onInit:

onInit: function() {
        sap.ui.core.UIComponent.getRouterFor(this).getRoute("CoObject").attachMatched(this._onRouteMatched, this);
    },

    _onRouteMatched: function(oEvent) {
        var sRoute = oEvent.getParameter("arguments").Route;
    }

and I need to use the Value of sRoute in this function:

_onWeiterButtonPress: function(oEvent) {
    var oRouter = this._getRouter();
    var AufNr = this.getView().byId("IptAufNr").getValue();
}

In need sRoute to check which tile the user pressed but I don´t know how to pass the value without setting in global?

Thanks for your Help


I think a solution can be to set the sRoute value on sessionStorage and use it in _onWeiterButtonPress. Here is an example:

sessionStorage.setItem('sRoute', sRoute);//for set the value
sessionStorage.getItem('sRoute';//for get the value

How can I pass a value from one function to another function without , (function(){ var a, c; // Not global, but available to all three functions function new1 (){ a = 5; } function new2(){ c = 6; } function new3(){ if(a < c)� I tried the following, trying to pass a variable from one JavaScript file to another JavaScript variable. My first JavaScript file: var x = "sachin"; My other JavaScript file can't access that x variable value. How do I solve this? I can access that x variable and same value in another file.


How about this:

_onRouteMatched: function (oEvent) {
        var sRoute = getArgumentsFromRoute(oEvent);
    }

_onWeiterButtonPress: function (oEvent) {

        var oRouter = this._getRouter();
        var AufNr = this.getView().byId("IptAufNr").getValue();
        var sRoute = getArgumentsFromRoute(oEvent);
    }

function getArgumentsFromRoute(oEvent)
    {
        return oEvent.getParameter("arguments").Route;
    }

javascript, Hello jaycastr,. A variable declared inside a JavaScript function will only be local if you write it like this: function func(){ var x = 5; }. However� It creates a local variable and passes its value to another function. The second function creates a global variable and sets a value in the first function. When the second function is called from the first function, a local variable is declared using the value of the global variable (set in the first function). – Proto Jul 21 '17 at 12:50


You can pass on objet as second parameter of the navTo methode.

    onWeiterPressed: function (oEvent) {

        this.getRouter().navTo("detailView", {
            aufNr: this.getView().byId("IptAufNr").getValue();
        });

    },

and then in the view you navigated to:

    _onRouteMatched: function (oEvent) {

        // Get passed object
        var sObjectId = oEvent.getParameter("arguments").aufNr;

    },

All written in the documentation ;)

Chapter 15. Functions, In JavaScript, you cannot pass parameters by reference; that is, if you pass a variable to a function, its value is copied and handed to the function (pass by value). Therefore, the function can't change the variable. If you need to do so, you must wrap the value of the variable (e.g., in an array).

Solved it whit help from @santhosh by declaring

_onRouteMatched: function(oEvent) {
    this.sRoute = oEvent.getParameter("arguments").Route;
}

now I can navigate from the one View to 3 different views depanding on which Tile the User clicked.
