使用 divStyle.match 时出现 Javascript 错误

Question

var values = divStyle.match( /-?[\d\.]+/g );

当我运行 yarn build 时，上面的代码给我一个错误。

error: unnecessary escape character: \. no-useless-escape

我该如何解决这个问题？

Answer 1

如前所述:Does a dot have to be escaped in a character class (square brackets) of a regular expression?

In a character class (square brackets) any character except ^, -, ] or \ is a literal.

所以在你的情况下不要逃避点:

var values = divStyle.match( /-?[\d.]+/g );
