Question

Flex4 datagrid中嵌入了LinkButton,点的时候删除该行?

<mx:DataGrid id="DataGrid1" x="59" y="79" editable="true" enabled="false" dataProvider="{dataArr.item}">
<mx:columns>
<mx:DataGridColumn headerText="" dataField="">
<mx:itemRenderer>
<fx:Component>
<mx:LinkButton label="删除" click="this.parentDocument.goo(event)" />
</fx:Component>
</mx:itemRenderer>
</mx:DataGridColumn >
</mx:columns>
</mx:DataGrid>

public function goo(evt:MouseEvent):void
{
var d:String=this.parentDocument.dataProvider.selectedItem.@id;
delete dataArr.itme[d];
//xmlwrite.testwrite(dataArr);
//currentState = "leve22";
}
这样为什么不行呢
var d:String=this.parentDocument.dataProvider.selectedItem.@id;
此行报错

Answer 1

delete dataArr.itme[d];
这一步删除操作用的不对吧，你再仔细看下api吧

Answer 2

从数据源里面删除，
