semantic-ui 下拉框

　　注意：在使用semantic的下拉框的时候，不仅需要引入semantic.css，还要引入semantic.js，最重要的是引入jquery。否则下拉效果不会显示。

　　并且，jquery必须先于semantic.js引入，因为semantic.js需要用到jquery。

1、标准的下拉框

<!DOCTYPE html>

<html>

<head>

    <meta charset="UTF-8">

    <title>下拉框</title>

    <link href="../dist/semantic.css" rel="stylesheet" />

    <script src="../jquery.js"></script>

    <script src="../dist/semantic.js"></script>

</head>

<body style="padding:30px">

<div class="ui selection dropdown">

    <input type="hidden" name="gender" id="gender">

    <i class="dropdown icon"></i>

    <div class="default text">性别</div>

    <div class="menu">

        <div class="item" data-value="1">男性</div>

        <div class="item" data-value="0">女性</div>

    </div>

</div>

<button class="ui button" id="btn">提交</button>

</body>

<script>

    $(document).ready(function(){

        $('.ui.selection.dropdown').dropdown();

        $("#btn").on("click",()=>{

            alert($("#gender").val());

        });

    });

</script>

</html>
