编程经验

1.判断是否登陆：
Action里写request.setAttribute("_javascript", "alert('您还没有登陆，请先登陆!')");
<logic:present name="JAVASCRIPT">
<script type="text/javascript">
<bean:write name="JAVASCRIPT" filter="false" />
</script>
</logic:present>
2.accountType ==null ||"".equals(accountType)写成公共方法
3.Action里的添加后跳转到查询页面：this.listProject(mapping, form, request, response);
4.Action可以返回void类型，比如登陆验证，然后用RequestDispatcher也可以
5.提交表单尽量用隐藏域hidden，Action用request.setAttribute("");
6.<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<base href="<%=basePath%>">
<script type="text/javascript" src="js/jquery-1.3.min.js"></script>
<script type="text/javascript" src="quser/js/list_qgroup.js"></script>
