Question

<script type="text/javascript" src="http://static.stackmob.com/js/2.5.3-crypto-sha1-hmac.js"></script>
<script type="text/javascript">
$j.ajax({
        dataType : 'json',
        url : "/api/core/v2/groups/", //or any other rest call here
        beforeSend: function(xhr) {
            var bytes = Crypto.charenc.Binary.stringToBytes('username' + ":" + 'password');
                    var base64 = Crypto.util.bytesToBase64(bytes);
            xhr.setRequestHeader("Authentication", "Basic " + base64);
        },
        success: function(data, status, xhr) {
            console.log("success!");
            console.log(data);
                        console.log(data[0]);
        }
    });

data的输出是

Object
    data: Array[25]
        0: Object
            contentTypes: Array[4]
            creationDate: "2012-05-31T20:21:20.532+0000"
            creator: Object
            description: "A discussion group for anyone interested in amateur radio."
            displayName: "amd-amateur-radio-forum"
            followerCount: 5
            groupType: "OPEN"
            id: 1133

            name: "AMD Amateur Radio Forum"
            resources: Object
            type: "group"
            viewCount: 62
            __proto__: Object
        1: Object
        2: Object
        3: Object

但是当我尝试输出data[0]或data[1]时，它们都会以undefined的形式返回。我不知道如何处理这个JSON对象。

alert(data)的输出是

[Object object]

所以我假设它是一个格式正确的JSON对象。

这是输出JSON.stringify（data）

实际上比那个

更长

Answer 1

如果要输出字符串化数据并且在其中有一个名为data的数组，则需要执行data.data [0]而不是data [0]。

如果你说：

，对你来说会更清楚一点

success: function(result, status, xhr){
  var data = result.data;

然后数据[0]就可以了。

使用多个子对象解析JSON对象
