实现在easyui中的datagrid，点击某一列的列头弹出combobox下拉框

 easyUI  datagrid在列头加下拉框，实现对列内容的筛选。

代码：

onLoadSuccess: function (data) {//Fires when data is loaded successfully.
            
            typeFilt();//表头类型下拉框
            
            $('#pp').pagination('refresh', {
                total: data.total,
                pageNumber: data.page
            });
            toopTip(".downloadPic","下载");
            toopTip(".delPic","删除");
        },

 

function typeFilt(){
    var title = $('.datagrid-header-row td[field="genre"] span');//素材类型列头标签
    var combobox = '<select name="type" >'
                 + '<option value="0" selected="selected">素材类别</option>'
                 + '<option value="1">视频广告</option>'
                 + '<option value="2">音频广告</option>'
                 + '</select>';
    title.html(combobox);
    $('#ty').combobox({
        panelHeight:'auto',
        editable:false,
        onChange:function(newValue,oldValue){
            console.log(newValue);
        }
    });
}
