我正在尝试使用此minecraft 服务器 API (JSON)来显示在我的网页中，例如...现在有（玩家）已连接。JSON 文件如下所示（外部）：
{

},
"cache": 1442690473 }
I want to fetch the data players (online) and display it on a html paragraph.... Using JavaScript or Jquery. I searched some solutions, using getJSON, but I couldn't make it work.. I tried using AJAX to make a request...
我想获取数据播放器（在线）并将其显示在 html 段落上......使用 JavaScript 或 Jquery。我使用getJSON搜索了一些解决方案，但我无法使其工作.. 我尝试使用 AJAX 发出请求......
// AJAX Request to JSON
$.ajax({
url: "https://mcapi.ca/query/mythalium.com/players",
// Handle as Text
dataType: "text",
success: function(data) {
// Parse JSON file
var json = $.parseJSON(data);
//Store data into a variable
// Display Players
$('#players').html('Currently there are: ' + json.players.now ' users');
}
});
And then display it using:
然后使用以下方法显示它：
<span id="results"></span>

You should change your AJAX success callback to:
您应该将 AJAX 成功回调更改为：
success: function(data) {
// Parse JSON file
var json = $.parseJSON(data);
//Store data into a variable
// Display Players
$('#results').html('Currently there are: ' + json.players.online' + users');
}
The problems are you're selecting the wrong spanelement - #playersinstead of #resultsand you're referencing the wrong JSON property - json.players.nowinstead of json.players.onlinelike in the sample response you provided.
问题是您选择了错误的span元素 -#players而不是#results您引用了错误的 JSON 属性 -json.players.now而不是json.players.online您提供的示例响应中的元素。
