js数组转json 、json转数组。数组转逗号隔开字符串、字符串转数组

数组转成json字符串
var arr = [1,2,3, { name : Jack } ];
JSON.stringify(arr);
json字符串转成数组
JSON.parse(jsonStr);
js 将数组转成逗号分隔的字符串
let arr = new Array(3);
arr[0] = "Zero";
arr[1] = "One";
arr[2] = "Two";
let result =  arr.join(",")
console.log(result)
//输出结果：
=> "Zero,One,Two"
1.数组转字符串
 let list = [1,2,3,4,5,6];
 list.join(",");
 console.log(list); // 打印结果："1,2,3,4,5,6"
2.字符串转数组
var text = "1,2,3,4,5";
var array = text.split(",");//逗号是分隔符
var array = text.replace(/\"/g, "");
