如何将这些ASCI代码转换为Unicode？

Question

jslint appears to complain here: jslint似乎在这里抱怨：

Unexpected '\' before 'X'.
    Priv.SELECTOR = /^(@|#|\.)([\x20-\x7e]+)$/;

Perhaps if I used Unicode things would work? 也许如果我使用Unicode，事情会起作用吗？

Answer 1

It seems that \\uXXXX notation is recognized by jslint as valid. 似乎jslint将\\uXXXX表示法识别为有效。 Use 采用

Priv.SELECTOR = /^([@#.])([\u0020-\u007e]+)$/;

or 要么

Priv.SELECTOR = new RegExp("^([@#.])([\\u0020-\\u007e]+)$");

Note that the backslashes must be doubled inside a RegExp constructor. 注意，反斜杠必须在RegExp构造函数中加倍。
