How to dynamically add tr and td of a table in ajax

This time I will show you how ajax can dynamically add tr and td of a table, and what are the precautions for how ajax can dynamically add tr and td of a table. 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:

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('暂无数据');break;
        case '1':
            $.each(data.data,function(i,n){
var $tr = $(""+
""+n.year+""+
""+n.province+""+
"");
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;
}
