AS3與JS互動

AS中註冊回調： 

ExternalInterface.addCallback("JSCallASToSelectItem", SelectStarFromOuter);

private function SelectStarFromOuter(_itemId:String):void...{
    var jsCalled :Boolean=true;
    var jsSelectStar:Star = Star(chartArea.getChildByName(_itemId));
    if(jsSelectStar != null)...{
        DoFocusStar(jsSelectStar,jsCalled);
    }
}

 JS中定義被AS調用和調用AS的函數： 

function ASCallJSToSelectItem(itemID)...{
    document.getElementById('txtItemId').value = "AS選中:"+itemID;
}
function selectItem()...{
    var itemID = document.getElementById('txtItemId').value;
    document.getElementById("StarsChart").JSCallASToSelectItem(itemID);
}

 HTML： 

<input type="text" id="txtItemId">
<input type="button" onclick="selectItem();" value="選中">
