ajax刷新是一种用户体验良好的刷新方式,这篇文章主要介绍了ajax异步请求刷新,感兴趣的小伙伴们可以参考一下，希望能帮助到大家。

在网站刷新的方法中，ajax刷新是一种用户体验良好的刷新方式，在结合ssh等流行的框架！最为常用了！下面就是常用一个ajax刷新表单的一个demo.

$(document).ready(function () {
  testchaxun();
   setInterval("testchaxun()",5000);
  });
  function testchaxun(){
    /* var selectId = $(&#39;#proviace&#39;).val(); */
    $.ajax({
    type : "POST",
     /* cache: false, */
    url : "WarningAction!warningdefQuery1.action",
    dataType : "json",
    success : function(data) {
      $(&#39;tr&#39;).remove(&#39;.datatr&#39;);
      for(var i=0;i<data.length;i++){
        if(data[i].pState == &#39;危险&#39;){
          $(&#39;.table-thtr&#39;).after(&#39;<tr class="datatr error-tr">&#39;+
           &#39;<td><img class="picture" src="&#39;+data[i].pPic+&#39;"/></td>&#39;+
           &#39;<td>&#39;+data[i].pName+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].uName+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].bHomenum+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].bNumber+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].eStart+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].wType+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].wTime+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].pAddress+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].uName+&#39;</td>&#39;+
           &#39;<td>&#39;+data[i].pState+&#39;</td>&#39;+
           &#39;<td><a href="WarningAction!waringInfor.action?WId=&#39;+data[i].wId +&#39;">详情</a></td>&#39;+
           &#39;</tr>&#39;);
        }else{
          $(&#39;.table-thtr&#39;).after(&#39;<tr class="datatr">&#39;+
         &#39;<td><img class="picture" src="&#39;+data[i].pPic+&#39;"/></td>&#39;+
         &#39;<td>&#39;+data[i].pName+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].uName+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].bHomenum+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].bNumber+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].eStart+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].wType+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].wTime+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].pAddress+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].uName+&#39;</td>&#39;+
         &#39;<td>&#39;+data[i].pState+&#39;</td>&#39;+
         &#39;<td><a href="WarningAction!waringInfor.action?WId=&#39;+data[i].wId+&#39;">详情</a></td>&#39;+
         &#39;</tr>&#39;);
        }

       }
     }
    });
   };
</script>

而在后台的WarningAction!waringInfor.action中接送两个参数，实现请求这个方法的必要条件！返回一个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";

  };
