Question

我如何使用javascript或jquery

从这种类型的对象中获取值

    {
        authResponse: {
            userID: "12345678912345",
            accessToken:"kgkh3g42kh4g23kh4g2kh34g2kg4k2h4gkh3g4k2h4gk23h4gk2h34gk234gk2h34AndSoOn",
            session_Key: true,
            expiresIn: "5183738",
            sig: "..."
        },
        status: "connected"
    }

我想从此对象获取会话密钥的值。我尝试在JSON中解析它，但这是无效的JSON格式，当我尝试使用obj.key获取值时返回undefined。我在检查会话时得到了这个回复。请通过以下链接了解更多详情

Answer 1

var obj = JSON.stringify({
    authResponse: {
        userID: "12345678912345",
        accessToken: "kgkh3g42kh4g23kh4g2kh34g2kg4k2h4gkh3g4k2h4gk23h4gk2h34gk234gk2h34AndSoOn",
        session_Key: true,
        expiresIn: "5183738",
        sig: "..."
    },
    status: "connected"
});

alert(obj.authResponse.userID); //"12345678912345"
alert(obj.status); //"connected"

假设您想要访问每个级别的值： -

myobj =  {
        authResponse: {
            userID: "12345678912345",
            accessToken:"kgkh3g42kh4g23kh4g2kh34g2kg4k2h4gkh3g4k2h4gk23h4gk2h34gk234gk2h34AndSoOn",
            session_Key: true,
            expiresIn: "5183738",
            sig: "..."
        },
        status: "connected"
    }


alert(myobj.authResponse.userID);//"12345678912345"
alert(myobj.status);//"connected"

如果密钥是数字使用arry表示法[]，否则点（.）可以帮助您访问孩子。
