Js字符串和数组之间的转换

1、字符串转换为数组

var string = '123,456,789';
var result = string.split(',');
console.log(result) //输出["123", "456", "789"]


var string2 = 'abcdef'
var result2 = string2.split('')
console.log(result2) //输出['a','b','c','d','e','f']

2、数组转换为字符串

var array = ['abc', 'def', 'hig']
var arrayResult = array.join(',')
console.log(arrayResult) // 输出"abc,def,hig"
array.toString()//输出"abc,def,hig"
