如何在JQuery中打印Freebase Topic接口的文本值

Question

如何打印此结果的文本值。我试过这个代码，但它失败了

var topicid = "/m/02jttf";
$.getJSON(service_url +'?callback=?',function(response) {
     $.each(response.values, function(i, Values) {
          $('<div>', {text:values['text']}).appendTo(document.body);
    });
});

结果示例

funcname({
 "id": "/m/02jttf",
 "property": {
  "/common/topic/article": {
   "valuetype": "compound",
   "values": [
    {
     "text": "Kano is a city in Nigeria and the capital of Kano State in Northern Nigeria. Its metropolitan...",
     "lang": "en",
     "id": "/m/02jttr",
     "creator": "/user/mwclikipedia_en",
     "timestamp": "2006-10-22T16:58:02.001Z",
     "property": {
      "/common/document/source_uri": {
       "valuetype": "uri",
       "values": [
        {
         "text": "hsaffffsd",
         "lang": "",
         "value": "sfffsfsfs",
         "creator": "/user/wikipedia_en",
         "timestamp": "2006-10-22T16:58:02.001Z"
        }
       ],
       "count": 1.0
      },

Answer 1

$.each(response.values, function(i, Values) {
          $('<div>', {text:values['text']}).appendTo(document.body);
    });

如果您有Values，并且正在打印values['text']，则values未声明。

你应该这样做

$.each(response.property, function(_, prop) {
      $.each(prop.values, function(_, value) {
          $('<div />', { text : value.text }).appendTo('body');
      });
});

Answer 2

看起来您需要更多的迭代才能访问内部values属性

var topicid = "/m/02jttf";
$.getJSON(service_url +'?callback=?',function(response) {
     $.each(response.property, function(_, prop) {
          $.each(prop.values, function(_, value) {
              $('<div />', { text : value.text }).appendTo('body');
          });
    });
});
