<option>1</option>
<option>2</option>
<option>3</option>
</select>

select标签里加个name="test1"

加了之后呢???

在test.php中：

var_export($_REQUEST('test1'));

你是要获得所有的option值？

很简单啊，有没有分！加个隐藏表单嘛，提交之前先用js将所有下拉值赋给隐藏表单，然后提交后的页面直接用该隐藏表单变量名就可以得到了！！！

<script language='javascript'>
function create_options_values(){
	var option = document.all.tags('option');
	var max = option.length;
	var str = '';
	var i;

	for(i=0;i<max;i++){
		str += option[i].innerText + ',';
	}

	document.getElementById('options_values').value = str;
}
</script>

<form id="Form1" name="Form1" method="post"  action="test.php" onsubmit="create_options_values();">    
<select id="test1" name="test1" ondblclick="lclick('LBMan', 'LBSelectMan')" style="width: 170px;height: 150px" size="2" runat="server" multiple> 
<option value="1">1 </option> 
<option value="1">2 </option> 
<option value="1">3 </option>                            
</select>
<input type='hidden' id="options_values" name="options_values" value="" />
<input  type="submit" value="查询" /> 
</form> 

test.php
