用jquery操作json数据[重复]

Question

我正在练习 Ajax 调用，但在访问返回的 JSON 数据时遇到问题。

我有下面的代码

$('button').on('click', function() { 
  $.ajax({
    url: 'http://quotesondesign.com/wp-json/posts?filter[orderby]=rand&filter[posts_per_page]=1',
    success: function(data) {
      console.log(data);
    },
    error: function() {
      console.log('error occured');
    },
    cache: false
  });
});

哪个输出

[
{
"ID": 1127,
"title": "Paul Rand",
"content": "<p>Good ideas rarely come in bunches. The designer who voluntarily presents his client with a batch of layouts does so not out prolificacy, but out of uncertainty or fear.  </p>\n",
"link": "https://quotesondesign.com/paul-rand-7/"
}
]

我只是想输出我的 JSON 对象的 content 和 link 属性。我尝试了以下方法：

$('.message').html(JSON.stringify(data));

哪个输出

[{"ID":2294,"title":"Josh Collinsworth","content":"
You do not need to have a great idea before you can begin working; you need to begin working before you can have a great idea.

\n","link":"https://quotesondesign.com/josh-collinsworth-3/"}]

我正在寻找操作 JSON 数据的标准方法，感谢所有帮助！

顾名思义，stringify 将 JSON 转换为字符串。 JSON 是原生 JavaScript，基于您的示例数据：

[
    {
        "ID": 1127,
        "title": "Paul Rand",
        "content": "<p>Good ideas rarely come in bunches. The designer who voluntarily presents his client with a batch of layouts does so not out prolificacy, but out of uncertainty or fear.  </p>\n",
        "link": "https://quotesondesign.com/paul-rand-7/"
    }
]

你得到一个对象数组（在方括号中）（在花括号中）。在这种情况下，它只是数组中的一个对象，所以你用data[0]访问数组中的第一个对象，然后得到它的@ 987654324@财产：

$('.message').html(data[0].content);
