jQuery遍历多层json数据_1..............@慕课网原创_慕课网

1、json与jsonp的区别（待查）

2、要遍历的数据如下：

{"status": "ok", "code": 200, "data": {"343946": {"8144": {"feed": 0, "instagram": 0, "livefyre": 21, "facebook": 0, "total": 21, "twitter": 0}}, "343945": {"2649": {"feed": 0, "instagram": 0, "livefyre": 42, "facebook": 0, "total": 42, "twitter": 0}}}}

3、数据来源：
https://coxnews.bootstrap.fyre.co/api/v1.1/public/comments/ncomments/MzQzOTQ1OjI2NDl8MzQzOTQ2OjgxNDQ==.json

4、代码如下：
<html> 
    <head> 
        <title>TODO supply a title</title> 
        <meta charset="UTF-8"> 
        <meta name="viewport" content="width=device-width, initial-scale=1.0"> 
        <script type="text/javascript" src="jquery.min.js"></script> 
        <script type="text/javascript"> 
            $(document).ready(function() { 
            //$.each( [4,1,2], function(i, n){ 
            //    alert( "Item #" + i + ": " + n ); 
            //}); 
            //$.each( { name: "John", lang: "JS" }, function(i, n){ 
            //    alert( "Name: " + i + ", Value: " + n ); 
            //}); 
                $.ajax({ 
                    dataType: 'jsonp', 
                    url: 'https://coxnews.bootstrap.fyre.co/api/v1.1/public/comments/ncomments/MzQzOTQ1OjI2NDl8MzQzOTQ2OjgxNDQ==.json', 
                    success: function(data) { 
                        var dataObj = eval(data).data; 
                        //一层循环 
                        $.each(dataObj, function(n1, value) { 
                            alert(n1); 
                                //二层循环 
                                $.each(value,function(n2,value1){ 
                                    alert(n2);

                                   //三层循环 
                                        $.each(value1,function(n3,value2){ 
                                            alert(n3); 
                                            alert(value2); 
                                        }); 
                                }); 

                            //for (var i = 0; i < value.length; i++) { 
                            //    alert(value[i]); 
                           // } 
                        }); 
                    } 
                }); 
            } 
            ); 
        </script> 
    </head> 
    <body> 
        <div>TODO write content</div> 
    </body>
