js 数组,字符串,json互相转换
数组转字符串
var arr = [1,2,3,4,'巴德','merge']; var str = arr.join(','); console.log(str); // 1,2,3,4,巴德,merge
字符串转数组
var str = '1,2,3,4,巴德,merge'; var arr = str.split(','); console.log(arr); // ["1", "2", "3", "4", "巴德", "merge"] 数组 console.log(arr[4]); // 巴德
字符串转数组,数组转数组格式化,数组格式化转数组
var str = '1,2,3,4,巴德,merge'; var arr = str.split(','); var strify = JSON.stringify(arr); console.log(arr); // ["1", "2", "3", "4", "巴德", "merge"] 数组 console.log(arr[4]); // 巴德 console.log(strify); // ["1", "2", "3", "4", "巴德", "merge"] 字符串 var arrParse = JSON.parse(strify); console.log(arrParse); // ["1", "2", "3", "4", "巴德", "merge"] 数组
