等效于JScript Runtime中的窗口 [英] Equivalent to window in JScript Runtime

问题描述

在普通的浏览器javascript环境中，总是有全局window对象可供使用，但是Microsoft JScript Runtime是否有默认的可访问全局对象，或者至少是一种检查对象的方法?

In a normal browser javascript environment, you always have the global window object to fall back on but is there a default accessible global object for the Microsoft JScript Runtime or at least a way to check for one?

推荐答案

根据

According to MSDN, there is a Global object, however a quick test reveals that it is not directly accessible:

WScript.Echo(Global.escape('hello world')); // Error: 'Global' is undefined

但是，您可以利用以下事实:全局环境中的this引用全局对象，并将引用保存到变量中:

What you can do, however, is take advantage of the fact that this in a global context refers to the global object and save the reference to a variable:

var __global__ = this;
WScript.Echo(__global__.escape('hello world')); // happy times
