hello all! this is my first post and its driving me crazy:

I want to write an actionscrip getURL in my flash movie on a certain frame that
will call this specific javascript code:

<script language="JavaScript" type="text/javascript">
ord=Math.random()*10000000000000000;
document.write('<a href="http://www.blahblahblah.com " target="_blank">');
document.write('<img src="http://www.blahblahblah.com/image1.jpg " width="0" height="0" border="0" alt=""></a>');
</script>

what is the syntax to use and where do I put the JS code?

all help is appreciated, thanks !
:D

Place the Javascript code inside of a function, and then use the ExternalInterface class's call() method to call the Javascript function from within ActionScript.

In the HTML:
Code: [ Select ]
<script language="JavaScript" type="text/javascript">

function makeImageLink()
{
  ord=Math.random()*10000000000000000;

  document.write('<a href="http://www.blahblahblah.com " target="_blank">');

  document.write('<img src="http://www.blahblahblah.com/image1.jpg " width="0" height="0" border="0" alt=""></a>');
}

</script>
  1. <script language="JavaScript" type="text/javascript">
  3. function makeImageLink()
  4. {
  5.   ord=Math.random()*10000000000000000;
  7.   document.write('<a href="http://www.blahblahblah.com " target="_blank">');
  9.   document.write('<img src="http://www.blahblahblah.com/image1.jpg " width="0" height="0" border="0" alt=""></a>');
  10. }
  12. </script>


In the Flash:
Code: [ Select ]
ExternalInterface.call("makeImageLink");

otherwise
Code: [ Select ]
getURL("javascript:javascriptfunctionName();");

should work as well.

getURL() doesn't give you as much control over the call. With ExternalInterface, you can more or less use the Javascript function as a remote procedure, complete with callbacks and all that other cool jazz.

very true. that is actually a much better solution.

unfortunately most people's flash/javascript interaction is something light weight like communicating with urchin or opening a window without a menu bar in which case I usually provide getURL() solution to make life easier.

thanks guys-
I am still having some bugs- I know its not a JS forum, but do you know if there is a problem if the function is not named from within the <head>tag? I have limited access to the html of the page i am embedding my content into so if there is a limitation on that I will try out the basic getURL method. ah well.

good stuff-
thanks
