我应该在ExtJS 4 MVC中定义全局函数？ [英] Where should I define global functions in ExtJS 4 MVC?

问题描述

我需要定义一些可以在我应用程序中调用的功能。
什么是最好的方法来实现这个？

I need to define some functions which i can call everywhere in my app. What is the best approach to achieve this?

推荐答案

个人而言，为了保持EXT-MVC尽可能，我有一个充满静态方法的Utilities类。这可以像任何其他类一样需要维护正确的依赖关系。这也确保了这些方法在EXT环境中运行，所以所有的EXT都可用。

Personally, to keep it as EXT-MVC as possible, I have a Utilities class full of static methods. This can be required like any other class to maintain proper dependency relations. This also ensures that the methods are run in an EXT environment, so all of EXT is available.

Ext.define('MyApp.Utilities', {
    statics: {
        foo: function (a, b) {
            return a + b;
        }
    }
});

Ext.define('MyApp.MyView', {
    extends: 'Ext.panel.Panel',
    requires: ['MyApp.Utilities'],

    initComponent: function () {
        MyApp.Utilities.foo(1, 2);
    }
});
