数组转字符串

1.join()方法

var s= ["a", "d", "a", "f", "g", "f", "s", "g"];
s.join()　　//"a,d,a,f,g,f,s,g"
s.join(" ")　　//"a d a f g f s g"
s.join('');　　//adafgfsg

Copy after login

字符串转数组

1.call()方法

var str = "adafgfsg";
var strArr = Array.prototype.slice.call(str,0);
console.log(strArr);

Copy after login

结果：["a", "d", "a", "f", "g", "f", "s", "g"]

2.正则表达式

var str = "adafgfsg";
var strArr = str.replace(/(.)(&#63;=.)/g,'$1,').split(',');
console.log(strArr);
var str = "adafgfsg";
var strArr = str.match(/\w/g);
console.log(strArr);

Copy after login

结果：["a", "d", "a", "f", "g", "f", "s", "g"]

3.直接用split()方法

var str = "adafgfsg";
var strArr = str.split('');
console.log(strArr);

Copy after login

结果：["a", "d", "a", "f", "g", "f", "s", "g"]

以上所述就是本文都给大家总结的全部内容了，希望大家能够喜欢。
