【问题描述】：

我想在 Bootstrap 4 中使用 datepicker https://bootstrap-datepicker.readthedocs.io/en/latest/index.html。

按照上面页面上的示例，我可以使其与 Bootstrap 3 一起使用。

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

    <link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.7.1/css/bootstrap-datepicker.min.css" rel="stylesheet"/>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
</head>
<body>

<main class="container">
    <div class="row" style="padding-top: 100px">
        <div class="col">
            <input data-date-format="dd/mm/yyyy" id="datepicker">
        </div>
    </div>
</main>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.7.1/js/bootstrap-datepicker.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
<script type="text/javascript">
    $('#datepicker').datepicker({
        weekStart: 1,
        daysOfWeekHighlighted: "6,0",
        autoclose: true,
        todayHighlight: true,
    });
    $('#datepicker').datepicker("setDate", new Date());
</script>
</body>

使用此代码日期选择器显示正确。

但在 Bootstrap 4 上做同样的事情：

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

    <link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.7.1/css/bootstrap-datepicker.min.css" rel="stylesheet"/>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"></head>
<body>

<main class="container">
    <div class="row" style="padding-top: 100px">
        <div class="col">
            <input data-date-format="dd/mm/yyyy" id="datepicker">
        </div>
    </div>
</main>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.7.1/js/bootstrap-datepicker.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script><script type="text/javascript">
    $('#datepicker').datepicker({
        weekStart: 1,
        daysOfWeekHighlighted: "6,0",
        autoclose: true,
        todayHighlight: true,
    });
    $('#datepicker').datepicker("setDate", new Date());
</script>
</body>

让它看起来不那么专业：

Bootstrap 4 版本中的字体和间距似乎搞砸了。

如何在 Bootstrap 4 中获得与 datepicker 相同的外观？

谢谢

【问题讨论】：

问题的标题误导了我。我以为它与官方引导日期选择器有关，但它只是一些第三方项目。

标签： datepicker bootstrap-4 bootstrap-datepicker

【解决方案1】：

你也可以像下面这样覆盖默认的日期选择器类：

默认引导字体大小是 1rem 或 16px 所以更新 .datepicker 类 font-size: 0.875em; 或/和更新单元格的宽度和高度：

.datepicker td, .datepicker th {
    width: 1.5em;
    height: 1.5em;
}

        /* solution 2: the original datepicker use 20px so replace with the following:*/
        
        .datepicker td, .datepicker th {
            width: 1.5em;

【解决方案2】：

来自文档：

bootstrap-datepicker.standalone.css

可用于在不依赖 Twitter Bootstrap 库的情况下包含日期选择器。

【解决方案3】：

你可以试试https://github.com/satyandra-softuvo/bootstrap4-datetimepicker

$.extend(true, $.fn.datetimepicker.defaults, {
    icons: {
      time: 'far fa-clock',
      date: 'far fa-calendar',
      up: 'fas fa-arrow-up',
      down: 'fas fa-arrow-down',
      previous: 'fas fa-chevron-left',
      next: 'fas fa-chevron-right',
      today: 'fas fa-calendar-check',
      clear: 'far fa-trash-alt',
      close: 'far fa-times-circle'
    }   
});
