我有 json 对象，但我无法访问其中的“名称”元素？

问题描述 投票：0回答：6

这是json数据。在我解析时它不起作用。但现在它有效了。

{ “2”：{ “餐厅”：“Naushijaan”， "订单": "HIHUN8", “交货时间”：“2016-06-18 上午 11:10”， “类型”：“送货上门”， "名称": "abc ddd", “地址”：“12356，勒克瑙，226010”， "电话": "67777799999", “总计”：“545.00 卢比”， “付款方式”：“货到付款”， “选择者”：“由管理员”， “日期”：“2016 年 6 月 18 日”， “地位”： { “处理”：2， “交付”：3， “完成”：4， “失败”：5 }, “动作”：“视图” }, “3”：{ “餐厅”：“啊哈”， "order": "HIHUN7", “交货时间”：“2016 年 6 月 12 日上午 11:32”， “类型”：“送货上门”， “名称”：“sk mishra”， “地址”：“520viram khand，勒克瑙，226010”， “电话”：“6799999999”， “总计”：“450.00 卢比”， “付款方式”：“货到付款”， “选择者”：“虚拟”， “日期”：“2016 年 6 月 12 日”， “地位”： { “完成”：4， “失败”：5 }, “动作”：“视图” },

这就是您访问名称字段的方式。

var yourJson = {"0":{"restaurant":"Bayleaf","order":"HIHUN10","delivery at":"04:43 PM 2016-06-22","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 831.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06\/22\/2016","status":"Waiting","action":"pending"},"1":{"restaurant":"Jungliee","order":"HIHUN9","delivery at":"03:40 PM 2016-06-21","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 465.00","pay by":"Cash On Delivery","picked by":"Dummy","date":"06\/21\/2016","status":{"Accepted":1,"Processing":2,"Delivered":3,"Completed":4,"Failed":5},"action":"view"},"2":{"restaurant":"Naushijaan","order":"HIHUN8","delivery at":"11:10 AM 2016-06-18","type":"Home Delivery","name":"dEEPAK rAI","address":"12356,Lucknow,226010","phone":"9120276440","total":"Rs 545.00","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06\/18\/2016","status":{"Processing":2,"Delivered":3,"Completed":4,"Failed":5},"action":"view"},"3":{"restaurant":"Aahaar","order":"HIHUN7","delivery at":"11:32 AM 2016-06-12","type":"Home Delivery","name":"sk mishra","address":"520viram khand,Lucknow,226010","phone":"9198979962","total":"Rs 450.00","pay by":"Cash On Delivery","picked by":"Dummy","date":"06\/12\/2016","status":{"Completed":4,"Failed":5},"action":"view"},"4":{"restaurant":"Bayleaf","order":"HIHUN6","delivery at":"08:29 PM 2016-06-11","type":"Home Delivery","name":"Dharmraj","address":"D-242Office G 19 Sector 63,Lucknow,201003","phone":"7428069025","total":"Rs 606.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06\/11\/2016","status":{"Completed":4,"Failed":5},"action":"view"},"5":{"restaurant":"Bayleaf","order":"HIHUN5","delivery at":"08:17 PM 2016-06-11","type":"Home Delivery","name":"Dharmraj","address":"D-242Office G 19 Sector 63,Lucknow,201003","phone":"7428069025","total":"Rs 606.60","pay by":"Cash On Delivery","picked by":"By Administrator","date":"06\/11\/2016","status":{"Completed":4,"Failed":5},"action":"view"}}

您的 json 是一个对象，要访问名称，您必须遍历属性：

$.each(data, function(i, e) {
  alert(e.name);
});

如果已经是json中的对象，直接访问即可：

// as single, hardcoded entry
var nameAt0 = data[0].name;
var nameAt1 = data[1].name;
...

// as loop
for( var i in data )
    if( data.hasOwnProperty(i) )
        var name = data[i].name;

它现在工作正常，每个答案都是正确的。我失踪了

 dataType: 'json'
   ,

'dataType:json' 在侧面 ajax 块中。

首先，你有一个非常不标准的 JSON 结构，但是，你不能作为 JSON 数组访问，所以，你必须将 JSON 解析为一个你可以更容易阅读的对象。 

    var MyJSONArray = [];
    $.each(YourJSON,function(index,e){
        MyJSONArray[] = e;
    ]

然后你就可以使用它了

    var restarant_1 = MyJSONArray[0].restaurant;

就是这样！ 享受
