#一、前台传后台
##A.前台传后台
Ajax+Json对象
var testurl = '/workteam/staff/forp.do';
$("#testResult") .click(function(){
$.ajax({
type : "POST",
dataType : "json",
url : testurl,
//数据为自己构造的。
data:{
"oldrole":oldrole,
"newrole":newrole,
"staffcode":zmstaffcode,
"staffname":zmstaffcode,
"pcode":pcode
},
success : function(result){
alert(result.entity[1].id);
/*toastr.error(,'警告信息');*/
}
});
});
无Ajax+序列化
var formData = $(".form-horizontal").serialize();//表格数据来自于序列化
$.post(testurl,formData,function(result){
if(result != 0){
//dosomething
}else{
//dosomething
}
});
##B.后台解析
###1.使用HttpServletRequest的getParameter:
HttpServletRequest request = getRequest();//getRequest()内部细节暂时不讨论
String name= request.getParameter("name");
###2.直接使用Spring MVC的注解:
public void get(@RequestParam String name)
###3.后台解析json对象
JSONObject json=JSONObject.fromObject(request.getParameter("data"));
String name = new String(json.getString("name"));
#二、后台传前台
1.@ResponseBody
@SuppressWarnings("unchecked")
@RequestMapping(value = "/test.do", method = RequestMethod.POST)
public @ResponseBody Map test(@RequestParam String name){
Map map = new HashMap();
return map;
}
##2.构造输出流输出
@SuppressWarnings("unchecked")
@RequestMapping(value = "/test.do", method = RequestMethod.POST)
public void test(@RequestParam String name){
Map map = new HashMap();
JSONObject result = JSONUtil.toJSONObject(map);
getOut().print(result);//构造输出流输出,细节省略
}
