如何在Javascript中设置全局变量? [英] How do I set a global variable in Javascript?

问题描述

我现在想设置一个全局变量.我知道这应该是一件坏事，但是当我精通此功能并且使用javascript更好时，我将回到这段代码并对其进行重构.

I want to set a global variable for right now. I know this is supposed to be a bad thing but when I get this functionality hammered down and a little better with javascript in general, I'll come back to this piece of code and refactor it.

我正在使用ajax调用，需要将返回服务器值存储在全局变量中.因此，如果我有:var = MyglobalVar = 'varFromMyServer';，如何准确设置此设置，以便可以从脚本中的任意位置访问它?

I'm using an ajax call and need the return server value to be stored in a global var. So, if I had: var = MyglobalVar = 'varFromMyServer';, how exactly do I set this up so I can access it from wherever I want in my script?
