不能用RegExp替换UTF-8字符

Question

I have a string with the UTF-8 character ↵ . To my understanding, if you want to replace a UTF-8 character in a string, you specify the character with its hexadecimal representation, like so:

var string = "↵↵↵Middle↵↵↵";
console.log("Match? " + /\u21b5/.test("↵"));
console.log(string);
string = string.replace("/\u21b5/g", "");
console.log(string);

It is a match, but the replace is not working. What am I missing?

Answer 1

您正在使用字符串而不是正则表达式

string = string.replace(/\u21b5/g, "");

Answer 2

replace

string = string.replace("/\u21b5/", "");

with

string = string.replace(/\u21b5/g, "");
