使用Javascript中的Regex一次替换多个字符串 [英] Replace Multiple String at Once With Regex in Javascript

问题描述

我尝试过:一次替换多个字符串而且: javascript用array全局替换它们是如何工作的.

I tried this : Replace multiple strings at once And this : javascript replace globally with array how ever they are not working.

我可以这样做吗(它的PHP):

Can I do similar to this (its PHP):

$a = array('a','o','e');
$b = array('1','2','3');
str_replace($a,$b,'stackoverflow');

结果将是:

st1ck2v3rfl2w

我想同时使用正则表达式.我怎样才能做到这一点 ?谢谢.

I want to use regex at the same time. How can I do that ? Thank you.

推荐答案

var str = "I have a cat, a dog, and a goat.";
var mapObj = {
   cat:"dog",
   dog:"goat",
   goat:"cat"
};
str = str.replace(/cat|dog|goat/gi, function(matched){
  return mapObj[matched];
});
