我有一个逗号分隔的字符串，我想把它转换成一个数组，这样我就可以遍历它。
有什么内置的功能吗？
例如，我有这个字符串
var str = "January,February,March,April,May,June,July,August,September,October,November,December";
现在我想用逗号将其拆分，然后将其存储在数组中。
当前回答
对于逗号分隔字符串的字符串数组：
let months = ["January","Feb"];
let monthsString = months.join(", ");
其他回答
请注意：
var a = "";
var x = new Array();
x = a.split(",");
alert(x.length);
将提醒1
返回函数
var array = (new Function("return [" + str+ "];")());
其接受字符串和对象字符串：
var string = "0,1";
var objectstring = '{Name:"Tshirt", CatGroupName:"Clothes", Gender:"male-female"}, {Name:"Dress", CatGroupName:"Clothes", Gender:"female"}, {Name:"Belt", CatGroupName:"Leather", Gender:"child"}';
var stringArray = (new Function("return [" + string+ "];")());
var objectStringArray = (new Function("return [" + objectstring+ "];")());

最短的
str.split`,`
var str=“一月、二月、三月、四月、五月、六月、七月、八月、九月、十月、十一月、十二月”；让arr=str.split`，`；控制台日志（arr）；
最简单的方法：
let myStr = '1, 2, 3, 4, 5, 7, 8';
const stringToArr = (myStr) => {
return myStr.split(',').map(x => x.trim());
};
let str = "January,February,March,April,May,June,July,August,September,October,November,December"
let arr = str.split(',');
这将导致：
["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
如果要将以下内容转换为：
["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
这：
"January,February,March,April,May,June,July,August,September,October,November,December";
use:
str = arr.join(',')
