Bootstrap jQuery DataTable 异步 AJAX 刷新表格数据实现

var postData = {
    "env_name" : new_env_name,
    "env_url": new_env_url,
    "env_desc" : new_env_desc
   };
   $.ajax({
    type: 'POST',
    url : '/test_env_add/',
    data : postData,
    dataType : 'json',
    success : function(data){
     $('#table_test_env').dataTable().fnClearTable(); //清空表格
     $('#table_test_env').dataTable().fnAddData(packagingdatatabledata(data),true); //刷下表格
     $("#modal-container-648308").modal("hide");
    },
    error:function(data){
     alert("新增失败");
    }
   })

 function packagingdatatabledata(data){
   var editHtml='<button href="#modal-container-648308" rel="external nofollow" data-toggle="modal" class="btn btn-xs btn-info" onclick="test_env_modify(this)"> <i class="icon-edit bigger-120"></i> </button> <button href="#modal-container-648300" rel="external nofollow" data-toggle="modal" class="btn btn-xs btn-danger" onclick="test_env_delete(this)"> <i class="icon-trash bigger-120"></i> </button>';
  var a=[]; //全部行数据的list
  var banddata = data.test_env_all;
  for(var key in banddata){
   var tempObj=[];  //一行数据的list
   tempObj.push(banddata[key].id);
   tempObj.push(banddata[key].name);
   tempObj.push(banddata[key].url);
