有人知道如何在JavaScript中从字符串中选择一个变量吗?这是我基本上想要实现的目标:

Does anyone know how could I select a variable from a String in JavaScript? Here's what I'm basically trying to achieve:

var myLang = "ESP"; var myText_ESP = "Hola a todos!"; var myText_ENG = "Hello everybody!"; console.log(myText_ + myLang); // This should trace "Hola a todos!"

谢谢！

推荐答案

var hellos = { ESP: 'Hola a todos!', ENG: 'Hello everybody!' }; var myLang = 'ESP'; console.log(hellos[myLang]);

我不喜欢将所有内容放在全局范围内，然后通过字符串访问窗口属性；所以这是另一种方法.

I don't like putting everything in global scope, and then string accessing window properties; so here is another way to do it.
