Page pass JSON object, background parsing

Components used foreground component: Json2.js from http://www.json.org/js.html background components: Json-lib-2.2.2-jdk15.jar

Foreground code 1 generates a list of JSON objects by page and then converts them into strings

Generate JSON object to String function Maketsjsonparam () {var tslist = new Array (); var ts = {' tn_id ': ', ' tn_trainsortie ': ', ' tn_takeofftime ': ', ' tn_landingtime ': ', ' tn_commander ': ', ' Tn_calendar ':  ''};  var List1 = $ (". Flightid");  var List2 = $ (". Tn_trainsortie");  var list3 = $ (". Tn_takeofftime");  var list4 = $ (". Tn_landingtime");//var LIST5 = $ (". Tn_realitylandingtime");  var List6 = $ (". Tn_commander");//var list7 = $ (". Tn_mechanician");//var List8 = $ (". Tn_notes");  var List9 = $ (". Tn_calendar");  alert (list1.length);  for (Var i=0;i<list1.length;i++) {ts = {};  ts.tn_id = List1[i].value;  Ts.tn_trainsortie = List2[i].value;  Ts.tn_takeofftime = List3[i].value;  Alert (list3[i].value) ts.tn_landingtime= list4[i].value;//ts.tn_realitylandingtime= list5[i].value;  ts.tn_commander= list6[i].value;//ts.tn_mechanician= list7[i].value;//ts.tn_notes= list8[i].value;   Ts.tn_calendar= List9[i].value;  Tslist[i] = ts;  } var str = json.stringify (tslist); return str;}

2 Submit the processed JSON string to the background

  Pass the JSON string to background function Savealltrainsortie () {var str = Maketsjsonparam ();//alert (str) var htmlstr = "1"; $.ajax ({         URL: '.. /train/savealltrainferrysortie.do ',            //url: ' ${ctx}/index.jsp ',            cache:false,            type: ' Post ',            async: False,          dataType: ' html ',                data:{             trainsortieliststr:str,          contentType: "application/ X-www-form-urlencoded;charset=utf-8 "            },            success:function (HTML) {                //alert (" HTML: "+html)                Htmlstr = html;           }        })      return HTMLSTR/    *  if (htmlstr==1) {     alert ("Save succeeded");     } */}

Background Code 1 parses the string into a Java object after processing.

public void Savealltrainferrysortie (HttpServletRequest request,httpservletresponse response) {String Trainsortieliststr = Request.getparameter ("Trainsortieliststr"); Jsonarray array = jsonarray.fromobject (TRAINSORTIELISTSTR); for (int i=0;i<array.size (); i++) {map ts= (map) array.get (i); String tn_id = "" +ts.get ("tn_id");  String Tn_trainsortie = "" +ts.get ("Tn_trainsortie"); String tn_takeofftime = "" +ts.get ("Tn_takeofftime");  String tn_landingtime = "" +ts.get ("Tn_landingtime"); String tn_realitylandingtime = "" +ts.get ("Tn_realitylandingtime"); String Tn_commander = "" +ts.get ("Tn_commander");//string Tn_mechanician = "" +ts.get ("Tn_mechanician");//string Tn_ Notes = "" +ts.get ("tn_notes"); String Tn_calendar = "" +ts.get ("Tn_calendar"); Trainsoriteferryservice.savetrainsortie (tn_id, Tn_trainsortie, Tn_  Takeofftime, Tn_landingtime, Tn_commander, Tn_calendar);              }try {response.setcharacterencoding ("UTF-8");              PrintWriter pw = Response.getwriter (); Pw.write ("1");             Pw.flush ();          Pw.close ();          } catch (IOException e) {e.printstacktrace (); }  }
