JavaScript數組沒有顯示出來，作爲一個數組

Question

我有一個數組，像這樣：

var data = {"result":"success","ids":["00000","54321","123","22222","11111","55555","33333","abc123","123abc","12345","44444"]} 
localStorage.ids = data.ids; 

但現在，當我做：

angular.forEach(localStorage.ids, function(id, key) { 
    console.log(id); 
}); 

我得到這樣的：

0 
0 
0 
0 
0 
, 
5 
4 
3 

而且等等。

當我console.log(JSON.stringify(localStorage.ids));我得到：

"00000,54321,123,22222,11111,55555,33333,abc123,123abc,12345,44444" 

有誰知道爲什麼會發生這種情況？

localStorage只存儲字符串。

localStorage.setItem('ids', JSON.stringify(data.ids)); // to save 

var ids = JSON.parse(localStorage.getItem('ids')); // to get
