select下拉框添加搜索功能

需要引用jquery插件select2
引入css

  <link href="/select2/4.0.5/css/select2.min.css" rel="stylesheet">

引入js依赖于jquery.js

<script src="/select2/4.0.5/js/select2.full.min.js"></script>

在select的class写入select2

<select id="xx" class="selectpicker show-tick form-control **select2**" > <option value="test1">test1</option> <option value="test2">test2</option></select>

代码块

<script type="text/javascript"> $(function () {    $(".select2").select2();    });    </script>
