1、字符串转换为数组 var string = '123,456,789'; var stringResult = string.split(','); console.log(stringResult) //输出["123", "456", "789"]   var string2 = 'abcdef' var string2Result = string2.split('') console.log(string2Result) //输出['a','b','c','d','e','f'] string2.split(",").map(Number);//输出[123,456,789] JSON.parse("[" + string + "]"); //输出[123,456,789]   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"
