Bootstrap 选择器多个关闭按钮

Question

我使用 bootstrap select 插件创建了多个 select-选项。我想添加关闭按钮，如 select-all 或 remove-all 按钮。

点击外面就关闭了。

$(function() {
  $('#multiple_selector').selectpicker();
});

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.4.0/css/bootstrap.css">
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.4.0/js/bootstrap.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.5/css/bootstrap-select.css">
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.5/js/bootstrap-select.js"></script>
<select id="multiple_selector" multiple data-actions-box="true">
  <option value="0">0</option>
  <option value="10">10</option>
  <option value="20">20</option>
  <option value="30">30</option>
  <option value="40">40</option>
  <option value="50">50</option>
  <option value="60">60</option>
</select>

Answer 1

documentation建议添加{ header:"header text" }这将添加一个关闭按钮；将空格作为 header 您将得到关闭按钮：

$(function() {
    $('#multiple_selector').selectpicker({header:" "});
});

您可以使用 class trigger 您的 select 操作按钮，如下所示。

$(function() {
  $('#multiple_selector').selectpicker();
  $('.actions-btn').on("click", function() {
    $('#multiple_selector').trigger('click');
  });

});

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}
