【问题描述】：

我想使用引导模式显示来自 JSON 文件的一些信息。

我有 12 个 HTML 按钮（12 个月），如果用户单击每个按钮，我想在 JSON 文件中显示数据。我的 HTML 页面是：

<!doctype html>
<html lang="en">
  <head>
    <title>show modal</title>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
    
  </head>
  <body>
    <button type="button" class="btn btn-outline-danger btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 1</button>
    <button type="button" class="btn btn-outline-info btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 2</button>
    <button type="button" class="btn btn-outline-warning btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 3</button>
    <button type="button" class="btn btn-outline-success btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 4</button>
    <button type="button" class="btn btn-outline-danger btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 5</button>
    <button type="button" class="btn btn-outline-info btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 6</button>
    <button type="button" class="btn btn-outline-warning btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 7</button>
    <button type="button" class="btn btn-outline-success btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 8</button>
    <button type="button" class="btn btn-outline-danger btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 9</button>
    <button type="button" class="btn btn-outline-info btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 10</button>
    <button type="button" class="btn btn-outline-warning btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 11</button>
    <button type="button" class="btn btn-outline-success btn-sm btn-block" data-toggle="modal" data-target="#modelId">Show id 12</button>

    <!-- Modal -->
    <div class="modal fade" id="modelId" tabindex="-1" role="dialog" aria-labelledby="modelTitleId" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title">MONTH NAME HERE</h5>
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                            <span aria-hidden="true">&times;</span>
                        </button>
                </div>
                <div class="modal-body">
                    DESCRIPTION MONTH here
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>

    <!-- jQuery first, then Popper.js, then Bootstrap JS -->

</html>

而我的 JSON 文件数据是：

我的 JSON 文件路径是：content/js/monthjson.json

{
  "months": [{
      "id": "1",
      "georgiamonth": "Jan",
      "description": "description Jan month",
      "suggestmonths": ""
    },
    {
      "id": "2",
      "georgiamonth": "Feb",
      "description": "description Feb month",
      "suggestmonths": ""
    },
    {
      "id": "3",
      "georgiamonth": "Mar",
      "description": "description mar month",
      "suggestmonths": ""
    },
    {
      "id": "4",
      "georgiamonth": "April",
      "description": "",
      "suggestmonths": "description April month"
    },
    {
      "id": "5",
      "georgiamonth": "May",
      "description": "description May month",
      "suggestmonths": ""
    },
    {
      "id": "6",
      "georgiamonth": "June",
      "description": "description June month",
      "suggestmonths": ""
    },
    {
      "id": "7",
      "georgiamonth": "July",
      "description": "description July month",
      "suggestmonths": ""
    },
    {
      "id": "8",
      "georgiamonth": "Aug",
      "description": "description Aug month",
      "suggestmonths": ""
    },
    {
      "id": "9",
      "georgiamonth": "Sept",
      "description": "description Sept month",
      "suggestmonths": ""
    },
    {
      "id": "10",
      "georgiamonth": "Oct",
      "description": "description Oct month",
      "suggestmonths": ""
    },
    {

      "suggestmonths": ""
    },
    {

      "georgiamonth": "Dec",
      "description": "description Dec month",
      "suggestmonths": ""
    }
  ]
}

感谢您的帮助。

【问题讨论】：

试试这个答案stackoverflow.com/questions/8787596/rendering-json-using-jquery 你可以使用点符号来访问你需要的值。所以把整个对象放在一个变量中
可以使用ajax访问json文件吗？还是在代码中静态可用？
是的 json 文件可以在文件夹中访问

标签： html jquery json bootstrap-4 bootstrap-modal

【解决方案1】：

您可以为每个按钮添加一个data-id 属性，这样您就知道点击了哪个按钮：

<button class="get-month-data ..." ... data-id="12">Show id 12</button>

那么事件处理程序代码将如下所示：

$(`button`).on(`click`, `.get-month-id`, function() {
  let id = this.attributes[`data-id`].value;

  $.getJSON(`content/js/monthjson.json`, function(months) {
    let month = months.filter(function(data) { return data.id === id; });

    $(`.modal-title`).text(month.georgiamonth);
    $(`.modal-body`).html(month.description);
  });
});
