JsHint警告：正则表达式文字可以与'/ ='混淆 [英] JsHint warning: A regular expression literal can be confused with '/='

问题描述

我在Javascript代码中有这一行：

I have this line in my Javascript code:

var regex = /===Hello===\n/;

JsHint在此行中给出了警告：

JsHint gives me a warning in this line:

A regular expression literal can be confused with '/='`

...但我不知道这个正则表达式有什么问题？如何避免此警告？

...but I don't know what's wrong with this regular expression? How can I avoid this warning?

推荐答案

问题是 / = 可以解释为除法和赋值，而不是正则表达式文字的开头。

The problem is that /= could be interpreted as a division and assignment, rather than the start of a regular expression literal.

您可以使用 RegExp 构造函数：

You can avoid the warning by using the RegExp constructor instead:

var regex = new RegExp("===Hello===\n");

似乎没有任何选项你可以设置告诉JSHint（或JSLint）忽略 / = ，所以你的选择要么解决它，要么忽略警告。

There doesn't appear to be any option you can set to tell JSHint (or JSLint for that matter) to ignore /=, so your choice is either to work around it or ignore the warning.
