jQuery+ajax adds list elements

This time I will bring you what are the precautions for adding list elements in jQuery ajax. The following is a practical case, let's take a look.

Function: ajax gets the background return data and dynamically adds tr/td to the table

html part:

<table>
<tbody></tbody>
</table>

ajax part:

var year = $('#year').val();//下拉框数据
var province= $('#province').val();//下拉框数据
$('table tbody').html('');
$.ajax({
  url:"/Plan/sendJson.html",
  type:"get",
  data:{
     'year':year,
     'province':province
  },
  datatype:'json',
  success:function(data){
     switch(data.msg)
     {
        case '0':
            $('table tbody').prepend('<tr><td colspan=&#39;2&#39;>暂无数据</td></tr>');break;
        case '1':
            $.each(data.data,function(i,n){
var $tr = $("<tr>"+
"<td>"+n.year+"</td>"+
"<td>"+n.province+"</td>"+
"</tr>");
var $table = $('table tbody');
$table.append($tr);
});
}
}
})

php background (thinkPHP processing):

$year = I('get.year');
$province = I('get.province');
$condition = array();
$year && $condition = array('eq',$year);
$province && $condition = array('eq',$province);
$dataList = M('Plan')->where($condition)->select();
if(false != $dataList){
  $data['msg'] = '1';
  $data['data'] = $dataList;
  echo json_encode($data);
  exit;
}else{
  $data['msg'] = '0';
  $data['data'] = '';
  echo json_encode($data);
  exit;
}
