jQuery EasyUI的TreeGrid查询功能实现方法

 function searchROM() {
  var product = $('#Product').bobox('getValue');
  var keytype = $('#keytype').bobox('getValue');
  var keywords = $('#keywords').val();
  var url = encodeURI('/GoodsROM/ROMList?product=' + product + '&keytype=' + keytype + '&keywords=' + keywords+'&'+Math.random());
  $.post(url, {}, function(data) {
   var d = data;//返回json格式结果
   $('#grid').treegrid('loadData',d);//加载数据更新treegrid
  }, 'json');
 }
