Question

Is it possible to use Javascript in flash. For example, as a simple test I am trying to use Javascript’s alert method when a button is clicked.

I am using AS3. Is it possible?

Answer 1

Like Marty mentioned, you can use the ExternalInterface class to execute a Javascript. Your options are to execute a function embedded in the (html) page code and create one from scratch. Because alert is a default function you can use its name as the first parameter for the call method (of ExternalInterface) and the string as the 2nd one.

If you provide a single parameter, you might wanna write a function instead to execute (or return) something.

btn.addEventListener(MouseEvent.CLICK, btnClicked);
function btnClicked(e:MouseEvent):void {
    ExternalInterface.call("alert","something");
    // or
    ExternalInterface.call("function(){alert('something');}");
}
