Extjs: share data between two functions

I have a property in my controller which I need to change its value in one method and access the updated value in another function. How can I do this?

Ext.define('App.controller.MyController', {
    extend: 'Ext.app.Controller',
     config:{
        Var : 'Test',
        },
    method1:function(){
        var me = this;
        var str1 = me.getVar();
        //change str1 here to Test2
    },
    method2:function(){
        var me = this;
        var str2 = me.getVar();
        //get updated value here (Test2)
    }
Solution

  • As your property is defined via config, getter and setter methods are already generated automatically, i.e. in method1 you can just call the setter to change the value:

    method1: function() {
    var me = this;
    me.setVar('Test2');
},

    Also refer to the documentation, as this very basic case is covered there.
