Javascript将“数组字符串”转换为数组

Question

Is it possible to turn this:

var a = "[0,0,1,1,0,0,1,[1,0,2]]";

into an array so it will work with this?

var newArray = a; // now newArray is [0,0,1,1,0,0,1,[1,0,2]], not "[0,0,1,1,0,0,1,[1,0,2]]"

Answer 1

var a = "[0,0,1,1,0,0,1,[1,0,2]]";
var result = JSON.parse( a );

Answer 2

var newArray = JSON.parse(a)

它将从字符串转换为数组。

Answer 3

In addition to JSON.parse you could use eval :

var a = "[0,0,1,1,0,0,1,[1,0,2]]";
var newArray = eval(a);

As for a discussion on whether to use JSON.parse or eval , see this SO discussion: JSON.parse vs. eval()

Answer 4

是的， 这些浏览器可能支持JSON.parse（） ，如果给定的字符串是有效的JSON表示形式，它将解析给定的String并将其转换为对象。

Answer 5

Also you can do:

var result = eval("[0,0,1,1,0,0,1,[1,0,2]]");

You result will be:

[0, 0, 1, 1, 0, 0, 1, Array[3]]
