jquery - fail in transmitting data in ajax -

-

i want make vote page. when click "", amount of vote plus meets "404 not found".(there no vote2.jsp in project because want refresh part of page.)

vote.jsp <body> <div class="testspan" data-id="1"><span>vote a</span>  num:<em>0</em></div> <div class="testspan" data-id="2"><span>vote b</span> num:<em>0</em></div> <div class="testspan" data-id="3"><span>vote c</span> num:<em>0</em></div> <div class="testspan" data-id="4"><span>vote d</span> num:<em>0</em></div> </body> ajax:     $(".testspan").click(function(){     var xsid = $(this).attr("data-id");     $.post("/vote/vote2",{         xsid:xsid     },function(data, textstatus){         var xsmap = data.xsmap;         $(".testspan").each(function(){             var id = $(this).attr("data-id");             $(this).find("em").html(xsmap[id]);         });     }, "json"); });  controller:     @requestmapping(value="/vote/vote2") public net.sf.json.jsonobject vote(int xsid){     net.sf.json.jsonobject json = new net.sf.json.jsonobject();     userservice.vote(xsid);     json.put("xsmap", userserviceimpl.xsmap);     return json; }

you need not have create vote2.jsp file. error valid, haven't specified context path in ajax url request.

to solve problem.

  1. use developer tools of browser , locate url raised ajax.
  2. the url should include context path.
  3. verify dispatcherservlet settings (in case using spring). check post.
