Ajax asynchronous request Refresh _ajax related

In the Web site Refresh method, Ajax refresh is a good user experience refreshing way, in combination with SSH and other popular framework! The most common! Here is a demo that uses an Ajax refresh form.

$ (document). Ready (function () {Testchaxun ();
  SetInterval ("Testchaxun ()", 5000);
  }); function Testchaxun () {/* var Selectid = $ (' #proviace '). val (); */$.ajax ({type: POST),/* Cache:false , */url: "Warningaction!warningdefquery1.action", DataType: "JSON", success:function (data) {$ (' tr '
      ). Remove ('. Datatr '); for (Var i=0;i<data.length;i++) {if (data[i].pstate = = ' dangerous ') {$ ('. Table-thtr '). After (' <tr class= ' dat ATR Error-tr "> ' + ' <td></td> ' + ' ;td> ' +data[i].pname+ ' </td> ' + ' <td> ' +data[i].uname+ ' </td> ' + ' <td> ' +data[i] . bhomenum+ ' </td> ' + ' <td> ' +data[i].bnumber+ ' </td> ' + ' <td> ' +data[i].estart+ ' &L
           T;/td> ' + ' <td> ' +data[i].wtype+ ' </td> ' + ' <td> ' +data[i].wtime+ ' </td> ' + ' <td> ' +data[i].paddress+ ' </td> ' + ' <td> ' +data[i].uname+ ' </td> ' + ' <td> ' +data[i].pstate+ ' &L T;/td> ' + ' <td><a href= ' warningaction!waringinfor.action?
        Wid= ' +data[i].wid + ' "> Details </a></td> ' + ' </tr> '); }else{$ ('. Table-thtr '). After (' <tr class= "Datatr" > ' + ' <td></td> ' + ' <td> ' +data[i].pname+ ' </td> ' + ' <td> ' +data[i].uname+ ' &L
         T;/td> ' + ' <td> ' +data[i].bhomenum+ ' </td> ' + ' <td> ' +data[i].bnumber+ ' </td> ' + ' <td> ' +data[i].estart+ ' </td> ' + ' <td> ' +data[i].wtype+ ' </td> ' + ' <td> ' + Data[i].wtime+ ' </td> ' + ' <td> ' +data[i].paddress+ ' </td> ' + ' <td> ' +data[i].uname+ ' &L T;/td> ' + ' <td> ' +data[i].pstate+ ' </td> ' + ' <td><a href= ' WarningAction!waringinfor.action?
        Wid= ' +data[i].wid+ ' > Details </a></td> ' + ' </tr> ');
   }

       }
     }
    });
};
 </script>

And in the background of the warningaction!waringinfor.action transfer two parameters, to achieve the requirements of this method! Returns a JSON

Public String waringinfor () {
     w= warningservice.getwarningbywid (WId);
     if (w!=null) {
       if (w.getpid ()!=null) {
       P =patientservice.getpatientbypid (W.getpid ());
      }
    }
    if (p!=null) {
      if (p.getpid ()!=null) {
        s= sickroomservice.getsickroombypid (P.getpid ());
      }
      if (P.getpequipmentid ()!=null) {
        e= Equipmentservice.getequipmentbyeid (P.getpequipmentid ()); 
      }
    }
    return "Waringinfor";
