问题描述

在Java和C ++中,我们可以全局存储变量,并可以从项目中的任何位置访问其值. 说,我在一个名为Residence的类中,并且我将作为INTresidenceNumber保存到名为houseNumberGlobalVariable的全局变量中.

In java and C++ we could store a variable globally and access its value from any where in the project. Say, i am inside a class called Residence and i am saving the residenceNumber which is a INT to a global variable called houseNumberGlobalVariable.

现在,我可以从项目中的任何类访问houseNumberGlobalVariable.以类似的方式,我可以使用EXTJS中的Global变量.

Now, i could access houseNumberGlobalVariable from any class in the project. In a similar fashion, is there a Global variable in EXTJS that i could use.

我需要从一个类中设置一个值,并从另一个类中访问它. EXT JS中的等效项是什么.我认为EXTJS中没有全局变量概念,但是等效概念是什么?

I need to set a value from one class and access it from another. What is the equivalent in EXT JS. I don't think there's a global variable concept in EXTJS, but what is the equivalent in it ?

推荐答案

只需在app.js中声明一个变量,它将用作全局变量.

Just declare a variable in app.js it will act as global variable.

var globalVar;

您可以在其中添加任何内容,例如

You can add anything into that like

globalVar.myStore = yourStore;
