javascript - 用新字符串替换字符串的中间部分

Question

我有一个字符串如下：

var email = "name(replace these parenthesis by @)domain.com"

如何(replace these parenthesis by @)使用 javascript 用 @ 替换部分？

Answer 1

email.replace("(replace these parenthesis by @)", "@")

Answer 2

如果您确定该模式，则可以使用正则表达式。(和@)之间的每个字符都将替换为@

var str = "name(replace these parenthesis by @)domain.com";
var patt1 = /\(.*@\)/i;
document.write(str.replace(patt1,"@"));

Answer 3

对于您呈现的字符串格式：

var email = "name(replace these parenthesis by @)domain.com";

这样做：

email.replace(/\(.*\)/g,"@");

会给

name@domain.com

Answer 4

如果内容与您提到的一样，(replace these paranthesis by @)您可以将其替换为：

var email = "name(replace these parenthesis by @)domain.com";
email.replace(/(replace these parenthesis by @)/g,"@");

还是您正在寻找更通用的东西？
