问题描述
我试图从我的ActionScript代码调用一个javascript函数,但它不工作;
as3:
if(ExternalInterface.available)
{
try
{
ExternalInterface.addCallback(changeDocumentTitle,null);
catch(error:Error)
js swfobject)
$ p $ function changeDocumentTitle()
{
alert('call from SWF');
}
有人知道可能会发生什么吗?
addCallback()是如果您想要将Flash应用程序中的ActionScript函数公开给HTML容器,那么可以通过JavaScript调用它。
HI,
im trying to call a javascript function from my actionscript code but its not working;
as3:
if (ExternalInterface.available)
{

{
ExternalInterface.addCallback("changeDocumentTitle",null);
}
catch(error:Error)
js (inside velocity file using swfobject)
function changeDocumentTitle()
{
alert('call from SWF');
}
anyone know what could be happenin?
If you are trying to invoke a JS function from within your Flex app, you want to use ExternalInterface.call(...) and not ExternalInterface.addCallback(...). From the docs:
http://livedocs.adobe.com/flex/3/langref/flash/external/ExternalInterface.html
addCallback() is used if you want to expose an ActionScript function from your Flash app to the HTML container so that it can be invoked via JavaScript.
