jquery - 在 jQuery 中将 JSON 字符串转换为对象

Question

我有一个 jQuery http 请求，它返回一个 JSON 字符串形式的对象。这里我要做的就是将 JSON 转换为 jQuery 对象并将值分配给 html 元素...以下是要转换的对象的结构:

var Userrights = {

            Id: // an id element
            ScreenRights: // this is a list with following elements
            {
                ScreenName: 
                Create:
                Read: 
                Update: 
                Delete:
                Approve: 
                Access: 
                Print: 
                Email: 
            };
        };

现在，当我收到如下所示的 JSON 字符串时:

{
    "Id": "Manager",
    "ScreenRights": [{
        "ScreenName": "CustomerScreen",
        "Create": true,
        "Read": false,
        "Update": true,
        "Delete": false,
        "Approve": true,
        "Access": true,
        "Print": true,
        "Email": true
    },
    {
        "ScreenName": "TraderScreen",
        "Create": true,
        "Read": false,
        "Update": true,
        "Delete": false,
        "Approve": true,
        "Access": true,
        "Print": true,
        "Email": true
    },
    {
        "ScreenName": "DistributorScreen",
        "Create": true,
        "Read": false,
        "Update": true,
        "Delete": false,
        "Approve": true,
        "Access": true,
        "Print": true,
        "Email": true
    }]
}​

现在我如何将此字符串转换为上述对象结构？

Jquery:

var obj = $.parseJSON(string);
console.log(obj);

话虽如此，如果您使用 jQuery 的 .ajax，您只需设置 dataType:'json'
