1、
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@taglib prefix="s" uri="/struts-tags"%> <!-- 必须加入struts2-dojo-plugin-相应版本.jar 才能使用ajax--> <%@taglib prefix="sx" uri="/struts-dojo-tags"%> <html> <!-- 必须加入struts2-dojo-plugin-相应版本.jar 才能使用ajax--> <s:head theme="xhtml" /> <sx:head parseContent="true" debug="true" /> <title>惠生活管理系统</title> <body> <a href="action.jsp">客户端API</a> <br> <div id="loginDiv"> <div id="errorDiv"></div> <s:form name="divLoginForm" id="divLoginForm" action="login_admin" theme="xhtml"> <s:label label="请输入用户名密码"></s:label> <s:textfield name="admin.name" label="账号" value="admin" /> <s:password name="admin.password" label="密码" value="admin" /> <!-- sx executeScripts--> <sx:submit value=" 登 录 " formId="divLoginForm" targets="loginSuccessDiv" executeScripts="true" /> </s:form> </div> <div id="loginSuccessDiv" class="div" style="display: none;"></div> </body> </html>

public String login() { if(iAdminService.validate(admin.getName(), admin.getPassword())!=0){ getRequest().getSession(true).setAttribute("name", admin.getName()); getRequest().setAttribute("status", "success"); }else { getRequest().setAttribute("status", "failed"); } return "script"; }

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@taglib prefix="s" uri="/struts-tags"%> <s:bean id="date" name="java.util.Date"/> <s:if test="%{#request.status=='success'}"> 欢迎您，<s:property value="#session.name"/>. 登录时间：<s:date name="%{#date}"/> <s:url action="logout_admin" id="divLogoutUrl"></s:url> <s:a href="%{#divLogoutUrl}" theme="xhtml" >注销</s:a> <script> //将error置空 document.getElementById('errorDiv').innerHTML=''; //将登陆框隐藏 document.getElementById('loginDiv').style.display='none'; //显示成功信息 document.getElementById('loginSuccessDiv').style.display=''; </script> </s:if> <s:elseif test="%{#request.status=='failed'}"> <script> document.getElementById('errorDiv').innerHTML="您输入的密码和账户名不匹配，请重新输入。"; </script> </s:elseif> <s:else> <script> //将成功信息置空 document.getElementById('loginSuccessDiv').innerHTML=''; //将登陆框显示 document.getElementById('loginDiv').innerHTML=''; //隐藏成功信息 document.getElementById('loginSuccessDiv').style.display='none'; </script> </s:else>
