Flex中通过调用setClipboard将DataGrid数据复制到剪贴板便于导出Excel的代码--复制

//generate header of CSV, only if it's not genereted yet

}

cursor.moveNext();

}

//set references to null:

dataProvider=null;

columns=null;

column=null;

return (header + "\r\n" + data);

}

}

}

前台

//复制datagrid的数据

private function copyDatagrid():void

{

System.setClipboard(DataGridDataExporter.exportCSV(datagrid));//datagrid是DataGrid的id

}
