哪些字符对 JavaScript 变量名有效? [英] What characters are valid for JavaScript variable names?

问题描述

哪些字符可用于命名 JavaScript 变量?

我想为工作中的非 JavaScript 用户创建一个小型的扩展库"(他们似乎对语言都很拘谨).我喜欢 jQuery 和 Prototype 都使用 $ 美元符号的方式，而且由于我使用 jQuery，我正在寻找另一个不错的单字符符号来使用.

我意识到我可以只测试一些字符，但我希望从一开始就缩小我的字符列表(考虑到未来与另一个流行库的集成，也许).

附言为了让您了解 Anthony Mills 的答案是多么错误:如果您要将所有这些规则总结在一个 JavaScript 的纯 ASCII 正则表达式中，它将是 11,236 个字符长.这是:

Which characters can be used for naming a JavaScript variable?

I want to create a small "extension library" for my non-JavaScript users here at work (who all seem to be squeamish when it comes to the language). I love how jQuery and Prototype have both use the $ dollar sign, and since I use jQuery, I'm looking for another nice single-character symbol to use.

I realize that I could just test out a number of characters, but I'm hoping to narrow down my list of characters to start with (in consideration of future integration with another popular library, perhaps).

解决方案

To quote Valid JavaScript variable names, my write-up summarizing the relevant spec sections:

An identifier must start with $, _, or any character in the Unicode categories "Uppercase letter (Lu)", "Lowercase letter (Ll)", "Titlecase letter (Lt)", "Modifier letter (Lm)", "Other letter (Lo)", or "Letter number (Nl)".

The rest of the string can contain the same characters, plus any U+200C zero width non-joiner characters, U+200D zero width joiner characters, and characters in the Unicode categories "Non-spacing mark (Mn)", "Spacing combining mark (Mc)", "Decimal digit number (Nd)", or "Connector punctuation (Pc)".

I’ve also created a tool that will tell you if any string that you enter is a valid JavaScript variable name according to ECMAScript 5.1 and Unicode 6.1:

P.S. To give you an idea of how wrong Anthony Mills' answer is: if you were to summarize all these rules in a single ASCII-only regular expression for JavaScript, it would be 11,236 characters long. Here it is:
