简介

Bootstrap Select是一个jQuery插件，通过多种选项增强默认的Bootstrap下拉选择，如：optgoup支持、自动完成、清除选择和实时过滤。

依赖项：

jQuery中。
Bootstrap程序5、Bootstrap程序4或Bootstrap程序3
字体很棒的图标（适用于Bootstrap程序4）。
AjaxBootstrap选择（用于Ajax数据获取）。可选。

安装：

# Yarn
$ yarn add bootstrap-select
 
# NPM
$ npm install bootstrap-select --save

如何使用它:

1.将jQuery Bootstrap Select插件和其他所需资源包含到您的Bootstrap页面中。

<!-- Bootstrap Stylesheet -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />
 
<!-- Bootstrap Select Stylesheet -->
<link href="/path/to/bootstrap-select.min.css" rel="stylesheet">
 
<!-- Bootstrap JavaScript -->
<script src="/path/to/cdn/jquery.slim.min.js"></script>
<script src="/path/to/cdn/bootstrap.min.js"></script>
 
<!-- Bootstrap Select Main JavaScript -->
<script src="/path/to/bootstrap-select.min.js"></script>
 
<!-- Bootstrap Select Language JavaScript -->
<script src="/path/to/i18n/defaults-LANGUAGE.min.js"></script>

2.只需将类“selectpicker”添加到您的select元素中即可。

<select class="selectpicker">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

3.您也可以通过调用“select”元素上的函数来初始化插件。

$('select').selectpicker();

4.所有默认插件设置。

$('select').selectpicker({
 
  // text for none selected
  noneSelectedText: 'Nothing selected',
 
  // text for no results
  noneResultsText: 'No results matched {0}',
  countSelectedText: function (numSelected, numTotal) {
    return (numSelected == 1) ? "{0} item selected" : "{0} items selected";
  },
 
  // text for max options
  maxOptionsText: function (numAll, numGroup) {
    return [
      (numAll == 1) ? 'Limit reached ({n} item max)' : 'Limit reached ({n} items max)',
      (numGroup == 1) ? 'Group limit reached ({n} item max)' : 'Group limit reached ({n} items max)'
    ];
  },
 
  // text for select all
  selectAllText: 'Select All',
 
  // text for deselect all
  deselectAllText: 'Deselect All',
 
  // enables done button
  doneButton: false,
 
  // text for done button
  doneButtonText: 'Close',
 
  // custom separator
  multipleSeparator: ', ',
 
  // basic class
  styleBase: 'btn',
 
  // button classes
  style: classNames.BUTTONCLASS,
 
  // 'auto' | integer | false
  size: 'auto',
 
  // title for dropdown select
  title: null,
 
  // values' | 'static' | 'count' | 'count > x'
  selectedTextFormat: 'values',
 
  // width
  width: false,
 
  // string | false
  container: false,
 
  // hides disabled options
  hideDisabled: false,
 
  // shows sub text
  showSubtext: false,
 
  // shows icons
  showIcon: true,
 
  // shows content
  showContent: true,
 
  // auto reposition to fit screen
  dropupAuto: true,
 
  // adds a header to the dropdown select
  header: false,
 
  // live filter options
  liveSearch: false,
  liveSearchPlaceholder: null,
  liveSearchNormalize: false,
  liveSearchStyle: 'contains',
 
  // shows Select All & Deselect All
  actionsBox: false,
 
  // icon base
  iconBase: 'glyphicon',
 
  // tick icon
  tickIcon: 'glyphicon-ok',
 
  // shows tick
  showTick: false,
 
  // custom template
  template: {
    caret: '<span class="caret"></span>'
  },
 
  // integer | false
  maxOptions: false,
 
  // enables the device's native select for the dropdown select
  mobile: false,
 
  // if true, treats the tab character like the enter or space characters within the selectpicker dropdown.
  selectOnTab: false,
 
  // boolean | 'auto'
  dropdownAlignRight: false,
 
  // padding
  windowPadding: 0,
 
  // If enabled, the items in the dropdown will be rendered using virtualization (i.e. only the items that are within the viewport will be rendered). 
  // This drastically improves performance for selects with a large number of options. 
  // Set to an integer to only use virtualization if the select has at least that number of options.
  virtualScroll: 600
  
});

5.API方法。

// Sets the selected value
$('.selectpicker').selectpicker('val', 'Mustard');
$('.selectpicker').selectpicker('val', ['Mustard','Relish']);
 
// Selects all items
$('.selectpicker').selectpicker('selectAll');
 
// Deselects all items
$('.selectpicker').selectpicker('deselectAll');
 
// Re-renders the plugin
$('.selectpicker').selectpicker('render')
 
$('.selectpicker').selectpicker('render');
 
// Enables mobile scrolling
$('.selectpicker').selectpicker('mobile')
 
// Modifies the class(es)
$('.selectpicker').selectpicker('setStyle')
// Replace Class
$('.selectpicker').selectpicker('setStyle', 'btn-danger');
// Add Class
$('.selectpicker').selectpicker('setStyle', 'btn-large', 'add');
// Remove Class
$('.selectpicker').selectpicker('setStyle', 'btn-large', 'remove');
 
// Programmatically updates a select
$('.selectpicker').selectpicker('refresh')
 
// Programmatically toggles the select
$('.selectpicker').selectpicker('toggle')
 
// Hides the select
$('.selectpicker').selectpicker('hide')
 
// Shows the select
$('.selectpicker').selectpicker('show')
 
// Destroy the select
$('.selectpicker').selectpicker('destroy')

6.可用的事件处理程序。

$('.selectpicker').on('changed.bs.select', function (e, clickedIndex, isSelected, previousValue) {
  // do something...
});
 
$('.selectpicker').on('show.bs.select', function (relatedTarget) {
  // do something...
});
 
$('.selectpicker').on('shown.bs.select', function (relatedTarget) {
  // do something...
});
 
$('.selectpicker').on('hide.bs.select', function (relatedTarget) {
  // do something...
});
 
$('.selectpicker').on('hidden.bs.select', function (relatedTarget) {
  // do something...
});
 
$('.selectpicker').on('loaded.bs.select', function () {
  // do something...
});
 
$('.selectpicker').on('rendered.bs.select', function () {
  // do something...
});
 
$('.selectpicker').on('refreshed.bs.select', function () {
  // do something...
});

7.要使用远程数据源，您需要在文档中加载Ajax Bootstrap Select扩展。

<link rel="stylesheet" href="/dist/css/ajax-bootstrap-select.css"/>
<script src="/dist/js/ajax-bootstrap-select.js"></script>

8.添加数据实时搜索属性。

<select id="selectpicker" class="selectpicker" data-live-search="true">
  ...
</select>

9.使用AJAX从远程数据源获取选项的示例JavaScript。

var options = {
      ajax          : {
        url     : '/ajax',
        type    : 'POST',
        dataType: 'json',
        // Use "{{{q}}}" as a placeholder and Ajax Bootstrap Select will
        // automatically replace it with the value of the search query.
        data    : {
          q: '{{{q}}}'
        }
      },
      locale        : {
        emptyTitle: 'Select and Begin Typing'
      },
      log           : 3,
      preprocessData: function (data) {
        var i, l = data.length, array = [];
        if (l) {
          for (i = 0; i < l; i++) {
            array.push($.extend(true, data[i], {
              text : data[i].Name,
              value: data[i].Email,
              data : {
                subtext: data[i].Email
              }
            }));
          }
        }
        // You must always return a valid array when processing data. The
        // data argument passed is a clone and cannot be modified directly.
        return array;
      }
  };
  
$('.selectpicker').selectpicker().filter('.with-ajax').ajaxSelectPicker(options);

10.自定义Ajax Bootstrap Select扩展的所有可能选项。
