javascript - 无法从 skybiometry 获取数据

Question

我正在尝试从 SkyBiometry 中获取照片的 tid在如下所示的回调函数中，但它不起作用。

function callback(data) {
      drawFaces($("#conent_demo_image"), data.photos[0], true);
      var tid = data.photos[0].tags[0].tid;

      $("#tid").text(tid);
    }

html:

<div id="tid">
  tid:   
</div>

Answer 1

根据SkyBiometry Demo的来源它应该是这样的:
