Answer 1

假设你的语言是 JavaScript，你首先需要解析 JSON（下面我使用 jQuery 的$.parseJSON方法），然后访问相应的属性和数组位置。要检索“C:\”，您可以这样做：

var sJSON = '{"Name":["C:\/","D:\/","E:\/","F:\/","G:\/","My Documents"]}';
var oJSON = $.parseJSON(sJSON);
alert(oJSON.Name[0]); //displays C:\

如果您使用的是 JavaScript，则可以使用eval()语句代替 a，$.parseJSON因为 JSON 在 JavaScript 中是可执行的，但使用$.parseJSON.

为您的语言使用 JSON 解析库。

在 JavaScript 中，您可以使用 JSON.parse。如果您的输出在 varoutput中，您将执行以下操作：

var obj = JSON.parse(output);
console.log(obj.path[0]);
