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。

一个很好的解决方案:
let obj = ['A','B','C']
obj.map((c) => { return c. }).join(', ')

一个很好的解决方案:
let obj = ['A','B','C']
obj.map((c) => { return c. }).join(', ')
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());
};
var array = string.split(',');
MDN引用,对于极限参数的可能意外行为非常有用。(提示:“a,b,c”.split(“,”,2)指向[“a”,“b”],而不是[“a,”b,c“]。)
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(',')
如果用户通过添加额外的空格键入错误。你可以用这样的东西。
tags: foo, zar, gar
const stringToArr = (string) => {
return string.trim.split(",");
};
