JS和FLEX的相互调用

JS调用FLEX方法：

1.首页在MXML文件中定义供外部调用的函数：

ExternalInterface.addCallback("prevEx",prevExtentClickHandler);

  

   2.JSP中调用

function prevEx()

{

        swfobject.getObjectById("resGridFlex").prevEx();

}

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

                        id="resGridFlex" width="100%" height="100%">

                    

        </object>

  

   flex如何调用JS方法：

1.在JS中定义函数

function CB_PointSelGeo(gridid){

}

2.在FLEX中调用JS方法

<mx:HBox>

                                <mx:Button label="楼宇" click="PointToInfo()" fontSize="12"/>

                                <mx:Button label="更多" click="PointSelectMore()" fontSize="12"/>

                        </mx:HBox>

                        <mx:Script>      

                                <![CDATA[

                                        private function PointSelectMore():void{

                                                ExternalInterface.call("CB_PointSelGeo('"+data.GRID_ID+"')");

                                        } 

                                        private function PointToInfo():void{

                                                ExternalInterface.call("CL_PointSelInfo('"+data.GRID_ID+"')");

                                        }

                                ]]>

                        </mx:Script>
