Hello! I am developing a movie reservation program using the spring MVC pattern
**/* Press the Register Rating button to register comments! Non-login -> Induce Login Pop-up Window
When logged in -> moviescore insert!
At the same time as the insert, select the movies core and spray it on the screen!
*/**
$("#btn_register").click(function(){
var currentScore = $('#div_rating').raty('score'); // horoscope
var cheklog = $("#loginid").val(); // Login ID
var ms_mid = $("#ms_mid").val(); // Get movie m_number
if(cheklog == null || cheklog==""){
alert("Not logged in!");
}
else{
//alert ("You're logged in?");
var params =$("#formId").serialize();
$.ajax({
url:"detailMovie.com?m_number='"+ms_mid+"'",
data:params,
success:function(data){
alert(data);
}
});Enter the code here`
//$("#formId").attr("action","insertMovieScore.com");
}
});
The reason why you have to do this part of url:url:"detailMovie.com?m_number='"+ms_mid+"""" is because When you do detailMovie.com, the controller requests the m_number parameter fee (because it extracts the data that fits the m_number with the where conditional statement when querying db) I am trying to update my registered rating right below when I register my rating by using Ajax without moving the page. This part is blocked right now ㅠ 이렇게 If I do this, the rating can be inserted, but when I select it and bring it back, the m_number is null in the updateMovie.com section, so I can't extract the information from the detailed page I don't know how to deal with this.Help me
This is the part of the controller that comes when you request detailMove.com,
@RequestMapping("/detailMovie.com")
public ModelAndView getMovie(@RequestParam(value="m_number", defaultValue="1") int m_number,HttpServletRequest request,HttpServletResponse response, HttpSession session){
ModelAndView mav = new ModelAndView();
System.out.println ("detail1: "+request.getAttribute("m_number"));
if(request.getAttribute("m_number")!=null && !request.getAttribute("m_number").equals(""))
{
//System.out.println ("before the error");
m_number = Integer.parseInt(request.getAttribute("m_number").toString());
System.out.println ("detail2: "+m_number");
}
mav.addObject("m",dao.getMovie(m_number));
return mav;
}
This is the part of the controller that comes when you do insertMovieScore.com!
@RequestMapping("/insertMovieScore.com")
public ModelAndView submit(MovieScoreVo ms,HttpServletRequest request,HttpSession session,HttpServletResponse response){
ModelAndView mav = new ModelAndView("redirect:/detailMovie.com");
int re = dao.insertMovieScore(ms);
request.setAttribute("m_number", ms.getMs_mid());
List<MovieScoreVo> list = dao.listMovieScore();
String json = "[";
The part where I make and send Json
json += "]";
}
try{
response.setContentType("text/plain"); //plainjson type1!!!!
response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
out.write(json);
out.flush();
out.close();
}catch(Exception e){System.out.println(e.getMessage());}
return mav;
}
It's going to work out, but it's weird.
Just in case
url:"detailMovie.com?m_number='"+ms_mid+"'",
This part
url: "detailMovie.com?m_number=" + ms_mid,
Fix it like this.
Please refer to the attached source I tested.

$.ajax({
url: '/hello.data?a=1',
data: 'b=2&c=3',
dataType: 'json',
success: function(data) {
console.debug('success');
$('#result').text(data.message);
}
})
