Access this.functionName() into another function

Question

I have a function I can access like : this.randomNumber() which output a random number like : 54851247

The goal of the question is to access this function into another function.

console.log(this.randomNumber()); // Output: 54851247
function anotherFunction() {
    console.log(this.randomNumber()); // Error
}

Error I get :

Uncaught TypeError: this.createTorrentId is not a function

Full code :

Ext.ns("Deluge.add");
Deluge.add.FileWindow = Ext.extend(Deluge.add.Window, {
    title: _("Add from File"),
    layout: "fit",
    width: 350,
    height: 115,
    modal: !0,
    plain: !0,
    buttonAlign: "center",
    closeAction: "hide",
    bodyStyle: "padding: 10px 5px;",
    iconCls: "x-deluge-add-file",
    initComponent: function() {
        Deluge.add.FileWindow.superclass.initComponent.call(this);
        this.addButton(_("Add"), this.onAddClick, this);
        this.form = this.add({
            xtype: "form",
            baseCls: "x-plain",
            labelWidth: 35,
            autoHeight: !0,
            fileUpload: !0,
            items: [{
                xtype: "fileuploadfield",
                name: "file",
                buttonCfg: {
                    text: _("Browse") + "..."
                }
            }]
        })
    },
    onAddClick: function(c, b) {
        console.log(this.randomNumber()); // Output: 54851247
        function anotherFunction() {
            console.log(this.randomNumber()); // Error
        }
    },
})

Declaration of the function:

Ext.ns("Deluge.add");
Deluge.add.Window = Ext.extend(Ext.Window, {
    initComponent: function() {
        Deluge.add.Window.superclass.initComponent.call(this);
        this.addEvents("beforeadd", "add", "addfailed")
    },
    randomNumber: function() {
        return new Date().getTime()
    }
});

Can you maybe post the whole code ? Where do your function randomNumber live ? Inside a class ? Where do you call your other function anotherFunction ? Inside the same class ? — Saraband, Jan 18 '19 at 09:33
you can save the scope into another variable then you can use it as per your wish. i have modified your code . check this fiddle https://jsfiddle.net/ypdnzmx7/ — RAGINROSE, Jan 18 '19 at 10:19

Return that from function from another function

function a(){console.log("ds")}

this refers to the current scope which in this case is changed. Basically it means that the randomNumber() should exist on all objects in order to be able to do

this.randomNumber();

I suggest you add this function to the global/window scope so than you can simply say

randomNumber();

The problem is I don't know how this function is actually declared – executable Jan 18 '19 at 09:35
Well, have you written it or what? Where do you manage to call it successfuly? – Rob Jan 18 '19 at 09:37
No I didn't written it. I will add the full code on how I call it – executable Jan 18 '19 at 09:37
