1、直接把表单的参数写在Controller相应的方法的形参中
@RequestMapping("/addUser1")
public String addUser1(String userName,String password) {
System.out.println("userName is:"+userName);
System.out.println("password is:"+password);
return "/user/success";
}
2、通过HttpServletRequest接收
@RequestMapping("/addUser2")
public String addUser2(HttpServletRequest request) {
String userName = request.getParameter("userName");
String password = request.getParameter("password");
System.out.println("userName is:"+userName);
System.out.println("password is:"+password);
return "/user/success";
}
3、通过一个bean来接收
@RequestMapping("/addUser3")
public String addUser3(User user) {
System.out.println("userName is:"+user.getUserName());
System.out.println("password is:"+user.getPassword());
return "/user/success";
}
4、通过json数据接收
$(document).ready(function(){
$("#button_submit").click(function(){
var name = $("#userName").val();
var pass = $("#password").val();
var user = {userName:name,password:pass};//拼装成json格式
$.ajax({
type:"POST",
url:"${pageContext.request.contextPath}/user/addUser4",
data:user,
success:function(data){
alert("成功");
},
error:function(e) {
alert("出错："+e);
}
});
});
});依然可以使用bean来接收json数据
5、使用jQuery的serializeArray() 方法序列化表单元素
$(document).ready(function(){
$("#button_submit").click(function(){
//序列化表单元素，返回json数据
var params = $("#userForm").serializeArray();
//也可以把表单之外的元素按照name value的格式存进来
//params.push({name:"hello",value:"man"});
$.ajax({
type:"POST",
url:"${pageContext.request.contextPath}/user/addUser5",
data:params,
success:function(data){
alert("成功");
},
error:function(e) {
alert("出错："+e);
}
});
});
});依然可以使用bean来接收json数据：
