jQuery $.get()问题

dy7766 2009-11-17 12:49:41

今天准备写个ajax效果，就用jQuery的$.get(),方法发送请求，结果死也没进到Action中，帮忙看看是怎么回事

js文件：



	<script type="text/javascript" src="util/jquery.js"></script>

	<script type="text/javascript">

		function findRegion(){

			var Sel = $("#selCritically");

			var criticrallyID=Sel.val();

			alert(criticrallyID);

			$.get("region.do");

		}

	</script>

Struts-conf.xml文件：



  <action

      parameter="op"

      path="/region"

      type="com.dy.MyLy.struts.action.RegionAction" />

Action文件
