Flash CS3 and Javascript

Question

A couple of weeks ago, I wrote in another thread about how
Flash CS3 (using AS3) can directly handle javascript. I must tell
you that this direct handling is limited. You cannot call custom
javascript functions from html this way. If you need to call
function in your html, you must still use ExternalInterface.
Flash CS3 has a new function called navigateToURL().
navigateToURL() is part of the flash.net package and is
asynchronous (does not return any kind of value).
Let's say you want to throw a simple javascript alert message
to a user. You need to first make a call to the URLRequest
constructor and pass it a string value that uses javascript
protocol. In the alert example, you'll be calling the string
"javascript:alert('Your first AS3 javascript call');" To those
familiar with HTML, this will look very very familiar. All put
together, it looks something like the code below....
This idea can be expanded on and added to custom event
handlers in classes for buttons and other things in your projects.
Remember though that you must call the javascript code as it
appears in the javascript protocol. So to open a popup window,
you'd need to use window.open( blah, blah, blah ). Personally, I
still use ExternalInterface to call my Javascript functions (if I
need them at all). The only reason I use navigateToURL is when the
browser I'm using does not support ExternalInterface.
Anyhow, the code for the above example is down below. If you
have questions, post them here.

Answer 1

k,
my post 2+ weeks ago was adrenaline driven and premature. the
example I just gave was the code I was talking about. Why I ever
posted that URLLoader was capable of javascript interaction is
beyond me. I know better. The purpose of my post was simply to
answer questions I've been getting in my e-mail and to clarify my
original post 2 weeks ago.
As I stated, navigateToURL is meant for specific scenarios
just as getURL was in AS1 and 2 which was replaced by navigateToURL
in AS3. This would be more for the Linux users and the a-typical
O/S users where ExternalInterface is not supported by the browsers
on those operating systems. I do not condone using navigateToURL or
getURL. I will always recommend external javascript files and
ExternalInterface. My apologies for leading anyone on with my
premature run-off of the typing finger.
