在 HTML 上打印 JSON 元素

Question

我正在尝试获取 Instagram 的标题 post，结果是 link https://api.instagram.com/oembed/?url=http://instagr.am/p/{{shortcode}}/ 即 JSON 的 return。我是否有机会仅从 JSON 获取标题并将该标题作为段落附加到我的 HTML？这是 JSON 的示例：

请注意，段落标记内是 JSON 上的“标题”。请帮助我，提前谢谢！

顺便说一句，这是我所做的：

<div id="log"></div>
<script>
  var url = "http://api.instagram.com/oembed?url=http://instagr.am/p/{{code}}/";
  jQuery(document).ready(function ($) {
      $.ajax({
          url: url,
          dataType: "jsonp", // important
          cache: false,
          success: function (data) {
              $("#log").append("<p> User: "+data.author_name+"</p>");
              $("#log").append("<p> Caption : "+data.title+"</p>");
          }
      });
  });
</script>

Answer 1

您可以使用 json.parse()

有关更多信息，请查看 MDN 网络文档：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

Answer 2

假设你得到一个 Json 字符串，您可以将字符串存储在变量中：

string jsonString = response;

然后，您将它变成一个 Json 对象，这样您就可以访问它的属性

var jsonObj = JSON.parse(jsonString)

最后，您可以将文本附加到 HTML。如果您使用的是纯 Javascript，则应将 ID 属性添加到 HTML

标签：

<p id="par"> </p>

在你的 Javascript 中：

document.getElementById("par").innerHTML  = jsonObj.title

这是一个工作示例：

Answer 3

如果您的数据成功地以字符串形式出现，那么您应该使用 JSON.parse() 解析该数据然后使用。如下所示。

var url = "http://api.instagram.com/oembed?url=http://instagr.am/p/{{code}}/";
jQuery(document).ready(function ($) {
  $.ajax({
    url: url,
    dataType: "jsonp", // important
    cache: false,
    success: function (data) {
      var dataJson = JSON.parse(data);
      $("#log").append("<p> User: " + dataJson.author_name + "</p>");
      $("#log").append("<p> Caption : " + dataJson.title + "</p>");
    }
  });
});

Answer 4

我上网了并且有效：

<div id="log">
  <p>{{caption}}</p>
</div>
<script>
  var xmlhttp = new XMLHttpRequest();
  xmlhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      var myObj = JSON.parse(this.responseText);
      document.getElementById("log").innerHTML = myObj.title;
    }
  };
  xmlhttp.open("GET", "https://api.instagram.com/oembed/?url=http://instagr.am/p/CEQc0ZGJH0f/", true);
  xmlhttp.send();
</script>

感谢大家的付出，真的很感激！
