convert string to json array
提问by robert
I get this response from an Ajax request. Javascript seems to intepret it as a string. (When I say alert this.responseText, the whole string is shown)
我从 Ajax 请求中得到了这个响应。Javascript 似乎将其解释为字符串。（当我说 alert this.responseText 时，会显示整个字符串）

It's not the safest thing in the world, but you can do this:
这不是世界上最安全的事情，但您可以这样做：
var value = null, txt = this.responseText;
eval("value = (" + txt + ")");
It might be a little safer to do:
这样做可能更安全一点：
var value = null, txt = this.responseText;
!function(window) { eval("value = (" + txt + ")"); }();
but there are still all sorts of potential hacks. You're better off using a library.
但仍然存在各种潜在的黑客攻击。你最好使用图书馆。

If you use jQuery, JSON.parse(this.responseString);or jQuery.parseJSON(this.responseString);should work.
如果你使用jQuery，JSON.parse(this.responseString);还是jQuery.parseJSON(this.responseString);应该可以的。
