将逗号分隔的字符串转换为数组

Question

I have the following string:

'"alpha", "beta", "gamma", "delta"'

How can I convert the string into an array such that:

array = ["alpha", "beta", "gamma", "delta"];

So I can call on individual elements of the array such that:

array[0] = "alpha"

I've attempted using str.split but am unsure of the correct usage to separate the quotation marks and commas.

Answer 1

Modify the string so that it's valid JSON , then JSON.parse() it:

 var str = '"alpha", "beta", "gamma", "delta"'; var json = '[' + str + ']'; var array = JSON.parse(json); console.log(array[0]) 

Answer 2

这将为您解决问题：

str.replace(/\\"/g, '').split(', ')

Answer 3

Remove the quotations and spaces, then split on the comma

var str = '"alpha", "beta", "gamma", "delta"';
var strArray = str.replace(/"/g, '').replace(/ /g, '').split(',');

Answer 4

Possibly more efficient than the others; trim off the 1st and last " characters and split on the ", " sequence.

 var str = '"alpha", "beta", "gamma", "delta"'; var str2 = str.substr(1, str.length - 2).split('", "'); console.log(str2);
