字符串转数组，怎么写？

Question

var a ="['a','b','c']";

转换成

b = ['a','b','c'];

Answer 1

var b = new Function("return " + a).call();

Answer 2

b=eval(a)

Answer 3

1、b = eval(a);
2、如果不想用eval，那就手动好了：

b = a.substring(2, a.length-2).replace(/','/g, ',').split(',');

Answer 4

var a ="['a','b','c']";
var result = a.substring(1, a.length - 1).split(',');
