将Unicode字符插入到JavaScript中 [英] Insert Unicode character into JavaScript

问题描述

我需要在我的html页面上插入一个欧米茄（Ω）。我使用它的HTML转义代码来做到这一点，所以我可以写&＃937; 并获得Ω。当我把它放入一个HTML元素时，这一切都很好;然而，当我尝试将它放入我的JS中时，例如 var Omega =&＃937; ，它将该代码解析为JS，整个事情都不起作用。任何人都知道如何去做这件事？

I need to insert an Omega (Ω) onto my html page. I am using its HTML escaped code to do that, so I can write Ω and get Ω. That's all fine and well when I put it into a HTML element; however, when I try to put it into my JS, e.g. var Omega = Ω, it parses that code as JS and the whole thing doesn't work. Anyone know how to go about this?

推荐答案

我猜你实际上想要 Omega 是一个包含大写的欧米茄的字符串吗？在这种情况下，你可以这样写：



I'm guessing that you actually want Omega to be a string containing an uppercase omega? In that case, you can write:

var Omega = '\u03A9';

（因为ω codepoint为U + 03A9的Unicode字符;即 03A9 为 937 ，除非写成四个十六进制数字。）

(Because Ω is the Unicode character with codepoint U+03A9; that is, 03A9 is 937, except written as four hexadecimal digits.)
