AS3与JavaScript之间的通讯

准确的来说应该是AS3与JavaScript之间的通讯，其通讯的机理就是：ExternalInterface，具体的使用方法在Flex或Flash的使用帮助里都有详细的说明。 

JavaScript发送变量到AS： 

Flex: 

ExternalInterface.addCallback(”setBoxArea”,receivedFromJavaScript); 

private function receivedFromJavaScript(value:String):void { 
Alert.show(value); 
} 

HTML: 

function setBox(o) { thisMovie(”lc”).setBoxArea(”hello”); } 

AS发送变量到JavaScript: 

Flex: 

var wrapperFunction:String = “getChartData”; 
var o:Object = new Object(); 
o.chartType = “line”; 
o.yField = yFieldCB.selectedItem; 
s = ExternalInterface.call(wrapperFunction,o); 
Alert.show(s); 

HTML: 

function getChartData(o) { 
alert(o); 
return o.chartType+o.yField; 
}
