我尝试使用他们的 API:https://en.wikipedia.org/w/api.php?action=parse&page=February_19&prop=text&formatversion=2&format=json

I tried using their API: https://en.wikipedia.org/w/api.php?action=parse&page=February_19&prop=text&formatversion=2&format=json

推荐答案

如果你想要没有标记的纯文本，你必须首先解析 JSON 对象，然后从 HTML 代码中提取文本:

If you want plain text without markup, you have first to parse the JSON object and then extract the text from the HTML code:

function htmlToText(html) {
   let tempDiv = document.createElement("div");
   tempDiv.innerHTML = html;
   return tempDiv.textContent || tempDiv.innerText || "";
}

const url = 'https://en.wikipedia.org/w/api.php?action=parse&page=February_19&prop=text&format=json&formatversion=2&origin=*';

$.getJSON(url, function(data) {
  const html = data['parse']['text'];
  const plainText = htmlToText(html);
  const array = [...plainText.matchAll(/^\d{4} *–.*/gm)].map(x=>x[0]);
  console.log(array);
});

更新:我根据下面的评论编辑了上面的代码.现在该函数提取所有列表项并将它们放入一个数组中.

Update: I edited the code above according to the comment below. Now the function extracts all the list items putting them into an array.
