hashMap.eachValue的使用风险
public function getAreaValue():Number { var value :Number = 0 ; var obj :Object = new Object(); obj.value = 0; obj.buildingValue = function( park:AbstractPark ):void { obj.value += park.industryData.areaValue ; } /*function buildingValue( park:AbstractPark ):void { trace( this ); value+=park.industryData.areaValue ; }*/ _parkHashmap.eachValue( obj.buildingValue ) ; Debug.trace( "getAreaValue"+obj.value) ; return value ; }
