Question

我正在尝试在下拉列表中添加复选框，但我不知道如何实现此目的。下面是我用来定义复选框的代码：

<html> 
    <head> 
        <title>Scrolling Checkboxes</title> 
        <script type="text/javascript"> 
        </script> 
    </head> 
    <body> 
        <div id="ScrollCB" style="height:150;width:200px;overflow:auto"> 
            <input type="checkbox" id="scb1" name="scb1" value="1">0-1 Hours<br> 
            <input type="checkbox" id="scb2" name="scb2" value="2">1-2 Hours<br> 
            <input type="checkbox" id="scb3" name="scb3" value="3">2-3 Hours<br> 
            <input type="checkbox" id="scb4" name="scb4" value="4">3-4 Hours<br> 
            <input type="checkbox" id="scb5" name="scb5" value="5">4-5 Hours<br> 
            <input type="checkbox" id="scb6" name="scb6" value="6">5-6 Hours<br> 
            <input type="checkbox" id="scb7" name="scb7" value="7">6-7 Hours<br> 
            <input type="checkbox" id="scb8" name="scb8" value="8">7-8 Hours<br> 
            <input type="checkbox" id="scb9" name="scb9" value="9">8-9 Hours<br> 
        </div> 
    </body> 
</html>

下面是我定义下拉列表的代码 - ：

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>Untitled Document</title>
    </head>
    <body>
        <?php 
            function  select_time($time_)
            { ?>
        <select id="ftime" name="selecteddate_t<?php echo $time_ ;?>">
            <?php for($t=0;$t<=23;$t++) { ?>
            <option value=" <?php echo $t;   ?>"><?php echo $t; ?></option>
            <?php } ?>
        </select>
        <?php } 
        ?>
        <form action="xyz.php" method="post">
            <?php echo "Time: "select_time('from');?>
        </form>
    </body>
</html>

我希望当任何一个单击下拉列表时，将显示一个复选框列表，他/她可以选择多个复选框。另外，请解释如何在变量中获取所有选定的值。我们正在尝试为用户提供选择多个时段的选项，根据选择，我们将向他/她显示所需的统计数据。我不知道我需要什么是安静可行的。我已经尝试了很多将复选框与下拉列表集成，但是我没有达到预期的结果。
