Javascript RegExp：匹配除换行符之外的任何内容（\\ r？\\ n）

Question

我想让我的RegExp与换行符匹配

\r?\n

Answer 1

This should do it:

/(?:[^\r\n]|\r(?!\n))/g

This matches either any character except \\r and \\n or a single \\r that is not followed by \\n .

Answer 2

you can use the negative delimiter !

so (?!(\\r|\\n))

try that

or this maybe

.+?(?!(\r|\n))

Answer 3

As an alternative suggestion why not avoid regexp?

var newText = oldText.replace("\r","").replace("\n","");

This will return the string removing all the instances of \\r and \\n
