正则表达式匹配一切

Question

I'm using the following regular expression to match everything:

/^(?=.{10,8000}$).*$/

But now I just realize that .* doesn't match the newline character. How can I make this regular expression match newlines?

Answer 1

所有空格+非空格=所有字符： [\\S\\s]

/^(?=[\S\s]{10,8000})[\S\s]*$/

Answer 2

Why do you use a regex?

var txt = "Hello World!";
if(length(txt) >= 10 && length(txt) <= 8000) {//match}

Answer 3

var filter =  /.*/gim;

这将匹配多行的所有内容。

Answer 4

用这个

 var filter = /[\w|\W]*/gim;

Answer 5

I think that is pretty much simpler, just use /.*/ . stands for any character and * allows any repetition of that character.
