实现action 交互
function getDate(){
$.ajax({
type:"post",
url:"login.xhtml",
data:{
page:"serveTime"
},
success:function(data){
var tt = data.split("/");
//$("#back").html(data);
$("#showTime").html("<font style='font-size:14px'>"+tt[0]+" "+tt[1]+" "+tt[2]+"</font>");
//alert(tt[0]+";"+tt[1]+";"+tt[2]);
}
});
======================
login.xhtml配置的action 地址，page :指明访问ACTION那个方法名
=====ACTION===里面的该方法======================
public ActionForward serveTime(ActionMapping arg0, ActionForm arg1, HttpServletRequest req, HttpServletResponse rep) throws Exception {
String[] dd = loginDao.returnDateMes();//dao层调用的方法
rep.setContentType("text/html;charset=UTF-8");//设置页面编码
PrintWriter out = rep.getWriter();//得到输出流
out.println(dd[1]);//输出字符串
return null;
}
=====SERVLET 交互==================================
function clcc(){
$.ajax({
type:"post",
url:"ajax.do",
data:{
name:'1231',
pwd:'369'
},
success:function(data){
alert("ds:"+data);
}
});
}
=============================
ajax.do配置的servlet路径
==SERVLET 如下=============================
public class AjaxServelet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException {
// TODO Auto-generated method stub
doPost(arg0, arg1);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse response) throws ServletException, IOException {
String u = req.getParameter("name");
String p = req.getParameter("pwd");
System.out.println(u+";"+p);
PrintWriter out = response.getWriter();
out.println(u+";"+p);
out.flush();
out.close();
}
}
==========================
servlet action 一样的，都是用输出流PrintWriter 来返回数据
