地图将在父窗口的子窗口和列表框中启动。 在Javascript的点击事件上,我希望能够在列表框中多选择相同的项目(状态)。你能帮忙吗?

<script src="jquery.js"></script>
<script type="text/javascript">
$(function() { //run when the DOM is ready
$("#planetmap area").click(function (e) {
// jQuery code, event handling callbacks here
$('#mymapselect option[value="' + this.id + '"]').attr('selected', 'selected');
});
});
</script>
我从http://learn.jquery.com/about-jquery/how-jquery-works/#jQuery:_The_Basics下载了jquery.js文件 并添加作为参考。现在,click事件适用于Imagemap区域。它会多选集列表框中的项目。
