我们经常会看到很多的网站会看到有下拉列表的内容进行直接增加与移除，下面我来介绍一款js Select下拉列表框进行多选、移除、交换内容实例
复制代码 代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<span class='wp_keywordlink_affiliate'><a href="tag/html" title="查看 html 中的全部文章" target="_blank">html</a></span>4/loose.dtd">
<<span class='wp_keywordlink_affiliate'><a href="tag/html" title="查看 html 中的全部文章" target="_blank">html</a></span>>

<title>Select下拉列表框进行多选、移除、交换内容</title>
<meta http-equiv="Content-Type" content="text/<span class='wp_keywordlink_affiliate'><a href="tag/html" title="查看 html 中的全部文章" target="_blank">html</a></span>; charset=gb2312">

<body style="font-size:12px">
<form name="form1" method="post" action="">
<table width="380" border="0" align="center" cellpadding="0" cellspacing="0">

<td width="150"><table width="150" border="0" cellpadding="1" cellspacing="1" bgcolor="#CAFAFC">

<td height="25" background="wp-content/uploads/2012/05/79760-772704496-8.gif" bgcolor="#FFFFFF"> 请选择：</td>
</tr>
<tr>
<td align="center" bgcolor="#FFFFFF"><select name="sel_place1" size="6" multiple id="sel_place1" style="width:100px " >
<option value="sel1">江苏省</option>

</table></td>
<td width="80" align="center" valign="bottom"><input name="sure1" type="button" id="sure1"
onClick="allsel(document.form1.sel_place2,document.form1.sel_place1);" value="<<">
<input name="sure2" type="button" id="sure2"

<td width="150"><table width="150" border="0" cellpadding="1" cellspacing="1" bgcolor="#CAFAFC">

</select></td>
</tr>
</table></td>
</tr>
</table>
</form>
<script language="javascript">
function allsel(n1,n2)
{
while(n1.selectedIndex!=-1)
{
var indx=n1.selectedIndex;
var t=n1.options[indx].text;
n2.options.add(new Option(t));
n1.remove(indx);
}
}
</script>
</body>
</html></td>
</tr>
</table>
