Bootstrap-select(selectpicker)的使用说明
官网api链接:http://silviomoreto.github.io/bootstrap-select/
1、首先引入selectpicker插件js,css
<link href="~/Content/bootstrap-select.css" rel="stylesheet" /> <script type="text/javascript" src="~/Scripts/bootstrap-select.js"></script>
由于:例子中用使用的是jquery语法和bootstrap前端框架,所以还要引入
<link rel="stylesheet" type="text/css" href="~/Content/bootstrap.css" /> <script type="text/javascript" src="~/Scripts/jquery-1.11.3.js"></script> <script type="text/javascript" src="~/Scripts/bootstrap.js"></script>
注意:jQuery.js引入时要在其他js文件之前,否则js中无法识别jQuery语法
2、示例代码:
<select id="codeMechineHouse" multiple class="selectpicker" data-none-selected-text="全部" data-live-search-placeholder="搜索" data-live-search="true" data-none-Selected-Text="请选择"> @foreach (var item in ViewBag.mechineNameLists) { <option value="@item.SYSTEMID">@item.HOUSENAME</option> } </select>
3、属性说明
selected ="selected" option选中状态(全选则需在循环遍历时option时,加在该属性)
如:
@foreach (var item in ViewBag.publishCodes) { <option selected ="selected" value="@item.Type">@item.Name</option> }
multiple:多选 (不加则为单选)
data-actions-box="true":全选,false全不选
data-live-search="true":查询
data-none-selected-text="全部":未选中时显示
data-max-options="10":最多可选条数
data-selected-text-format="count > 3" 显示选择项(多选的数量在三个以下,显示文本,大于三个显示:“选中{总数}的{选中数}项”)
如图:
//清空selectpicker 清空选择
$("#codeMechineHouse").val("").trigger("change")
//刷新selectpicker
$(".selectpicker").selectpicker("refresh");
//获取selectpicker的值(字符串输出,逗号分隔)
第一种:
function getSelectpickerValue() { var v = ""; //直接对selectpicker插件val(),只能获取到一个对象数组 var values = $("#codeMechineHouse").val(); if (values != null && values.length > 0) { for (var i = 0; i < values.length; i++) { v += values[i] + ","; } } return v; }
第二种(简洁版):
//格式如:"2,3,4" $("#codeMechineHouse").val().toString(),
//获取selectpicker的文本(字符串输出,逗号分隔)
function getSelectpickerText() { var v = ""; var texts = $("#codeMechineHouse option:selected"); for (var i = 0; i < texts.length; i++) { v += texts[i].innerText + ","; } }
//更简洁的获取值的写法:
var selectedValues = []; $(".selectpicker option:selected").each(function () { selectedValues.push($(this).val()); });
第二种初始化方式:通过ajax获取到后台数据,回显加载selectpicker
<select multiple class="selectpicker show-tick" style="outline: none;width:200px;" data-live-search="true" id="select_article" name="select_article"> </select>
$('.selectpicker').selectpicker({ noneSelectedText: '请选择', liveSearch: true, size:5 //设置select高度,同时显示5个值 }); $(window).on('load', function () { var sid = $("#select_article").val(); $('.selectpicker').selectpicker('val', ''); $('.selectpicker').selectpicker('refresh'); $.ajax({ method:'POST', url:'/Slider/GetOptionData', dataType:'json', success: function (res) { var html=""; console.log(res); for (var i = 0; i < res.content.length; i++) { //selected='selected' 勾选选择项 html += "<option value='" + res.content[i].tid + "' selected='selected' data-name='"+res.content[i].name+"'>" + res.content[i].name + "</option>"; } $("#select_article").html(html); $('.selectpicker').selectpicker('refresh');//加载select框选择器 } }); });
效果图:
第三种回显的方式:
//将类似于"9,10,11"的字符串转换为["9","10","13"]这样的数组,回显勾选上原来的选择项
$("#add_senType").selectpicker('val', data.sentype.split(","));
效果图:
选择改变事件:
$('#select_article').on('changed.bs.select', function (e, clickedIndex, isSelected, previousValue) { if (isSelected == null) { //控件初始化,页面加载,不属于用户操作,不提示 return; } alert("用户修改了项!"); });
