With jQuery you could do $("#list option:selected").text(); to get the text of the selected option $("#list option:selected").val(); to get the value behind the selected option
EDIT:
where #list is the id of your select tag

我认为以下解决方案更好地获取VALUES：
$("#list option:selected").val();

Here's a very simple code that tells you how many you selected on every change:
For the Html Code:
<html>
<body>
<select multiple="true">
<option>Volvo</option>
<option>Saab</option>
<option>Mercedes</option>
<option>Audi</option>
</select>
</body>
</html>
Use this jQuery Code:
$("select").change(function() {
alert($("option:selected").length);
});
Here's a live example: http://jsfiddle.net/hesher/3M36e/

您可以使用纯JavaScript，例如：document.getElementById（'valumethod []'）。value
