flex datagrid拷贝整行方法

 

package common { import flash.events.ContextMenuEvent; import flash.system.System; import flash.ui.ContextMenu; import flash.ui.ContextMenuItem; import mx.controls.Alert; import mx.controls.DataGrid; public class CopyContent { private static var dg:DataGrid; public function CopyContent() { } //模块加载完成后初始化控件右键菜单 public static function initMenu(dataGrid:DataGrid):void { dg = dataGrid; createMenu_dg_Users(); Alert.show("success") } /** 控件初始化,创建右键菜单 * */ private static function createMenu_dg_Users():void{ var dg_ontextMenu:ContextMenu=new ContextMenu();//创建右键菜单 dg_ontextMenu.hideBuiltInItems();//隐藏内置菜单 var renameMenuItem:ContextMenuItem=new ContextMenuItem("拷贝整行"); dg_ontextMenu.customItems.push(renameMenuItem); renameMenuItem.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT ,copy); dg.contextMenu=dg_ontextMenu; } /** 销毁控件的右键菜单 * */ private static function destroyMenu_dg_Users():void{ var dg_ontextMenu:ContextMenu=dg.contextMenu; dg_ontextMenu.removeEventListener(ContextMenuEvent.MENU_SELECT,copy); } /** * 拷贝功能 **/ private static function copy(event:ContextMenuEvent):void{ // event.keyCode==65 var copyContent:String = ""; if(dg.selectedItem){ for(var i:int=0;i<dg.columns.length;i++){ copyContent = copyContent + dg.selectedItem[dg.columns[i].dataField] +"/n" } System.setClipboard(copyContent); }else{ Alert.show("请先用鼠标左键选择某行拷贝！") } } } } 

 

在使用的组件加入 initialize =init（）

 

 

//模块加载完成后初始化控件右键菜单

public function init():void

{

    CopyContent.initMenu(this.dg);

}

 

this.dg是定义的datagrid id名

 

 

改造后的，用于一个页面多个datagrid。备份其实上面那个也可以用与多个。再每个datagrid click事件调用即可。
