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