在 HTML 上打印 JSON 元素

Question

我正在嘗試獲取 Instagram 的標題帖子並最終得到此鏈接https://api.instagram.com/oembed/?url=http://instagr.am/p/{{shortcode}}/這是返回的 JSON。 我是否有機會僅從 JSON 獲取標題並將該標題作為段落附加到我的 HTML 中？ 這是 JSON 的示例：

Answer 1

您可以使用 json.parse()

有關更多信息，請查看 MDN 網絡文檔： https : //developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

Answer 2

假設你得到一個 Json 字符串，你可以將字符串存儲在一個變量中：

string jsonString = response;

然后，您將其轉換為 Json 對象，以便您可以訪問它的屬性

var jsonObj = JSON.parse(jsonString)

最后，您可以將文本附加到 HTML 中。 如果您使用純 Javascript，您應該向 HTML 添加一個 Id 屬性

標簽：

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

在你的 Javascript 中：

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

這是一個工作示例：

Answer 3

如果您的數據作為字符串成功傳入，那么您應該使用JSON.parse()解析該數據，然后使用。 像下面。

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

我上網，它的工作原理：

<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>

感謝大家的付出，真的很感謝！
