一般的做法如下: let obj = {}; // 遍历data的所有属性 let dataKeys = Object.keys(data); dataKeys.map(key => { // 为data
return $server->send($fd, Server::format(Server::SET, array_keys($server->data))); }else{ $dataKeys..., $key); $values = array_filter($dataKeys, function($value) use ($key){ return preg_match
程序示例 通过下面的代码获取右键点击位置所在的路径: project = e.getProject(); selectGroup = DataKeys.VIRTUAL_FILE.getData...public void actionPerformed(AnActionEvent e) { project = e.getProject(); selectGroup = DataKeys.VIRTUAL_FILE.getData

针对DataGrid无法提供行主键的问题,它提供了两个全新的属性:DataKeys和DataKeyNames!...DataKeys:获取一个 DataKey 对象集合,这些对象表示 GridView 控件中的每一行的数据键值。 ...DataKeyNames = new string [] { "id" }; 这样,当进行数据绑定时,GridView会自动用键值填充DataKeys集合,从而在绑定或者回传后可以通过...DataKeys集合来获取某一行的键值,例如假设想获取第i行的id键值,其代码如下: //获取第i行的id键值,注意该索引即行的索引,从header到footer都算在内 string id...DataKeys [ i ][ "id" ]. ToString (); //通过键值对数据进行处理…… 由此可见,GridView提供了新的机制来绑定额外的数据到每一行。
GridView如果不绑定数据源控件,则以下两种方式,无法获取主键: e.Keys[0].ToString() e.Keys["id"].ToString() 请使用以下方式获取主键: gv.DataKeys...[e.RowIndex].Value */ int id = int.Parse(GridView1.DataKeys[e.RowIndex].Value.ToString
