flex 多个方法使用一个结果处理函数

<mx:RemoteObject id="tarBiz" destination="targetBiz" showBusyCursor="true"> <mx:method name="checkName" result="checkHandle(event)" fault="faultHandle(event)"/> <mx:method name="addTarget" result="checkHandle(event)" fault="faultHandle(event)"/> </mx:RemoteObject> as: import mx.rpc.remoting.mxml.Operation; private var op:Operation=null; private function a():void { tarBiz.checkName(); op=tarBiz.getOperation("checkName") as Operation; op.arguments="a"; } private function b():void { tarBiz.addTarget(); op=tarBiz.getOperation("checkName") as Operation; op.arguments="b"; } private function checkHandle(evt:ResultEvent):void{ var opn:Operation=tarBiz.getOperation("checkName") as Operation; if(opn.arguments=="a"){ 操作。。。 } if(opn.arguments=="b"){ 操作。。。 } }
