html - 在 HTML 页面中将数据从 JSON 文件显示到引导模式

问题描述

我想使用引导模式显示来自 HTML 中的 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>

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",

解决方案

您可以为每个按钮添加一个data-id属性，以便知道单击的是哪个按钮：

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

然后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);
  });
});
