You already posted in the this thread, but this is good reference for anyone reading this thread.

Any chance you could update that link for the new forums so we know where you're trying to send us?

I'm stuck. . . I'm trying to get my "Next" button to appear after the .mpr is finished, but the file is too complicated to use an action when done playing; instead, the .mpr file requires javascript. I'm using using a Media Semantics Character and, per their instructions, added to the script a URL command with javascript. It tries to open a page in preview mode, so have been publishing each test with no more than an error on the page when the URL command plays.

Here's the javascript. . . "javascript:NextGreen.actionShow()" The second field is blank per their instructions too.

NextGreen is the name of the button, but the image is Next001.gif. . . . do I need to use that instead? If so, with the".gif?" I've tried copying it from the inherent list to the page itself, publishing to html, with no better results. I tried "javascript:trivNextPage() and it works, so I know the actionShow should work in thoery.

I'm not a programmer, so I rely on copy & paste. . . any help would be much appreciated.

Thanks,
Tim

Here's the javascript. . . "javascript:NextGreen.actionShow()" .... I tried "javascript:trivNextPage() and it works, so I know the actionShow should work in thoery.

You cannot refer to Lectora objects such as buttons (texts, actions, object groups etc.) by the names you give them. Instead, you should refer to Lectora objects by their supersecret names that Lectora assigns automatically. So not "NextGreen.actionShow()" but rather "button7923.actionShow()".

To find the secret name, hit Preview in Browser, choose View Source, dig through the JS part of the file. Look for e.g. "NextGreen.gif", it will be connected to the button.

If anyone knows a shorter way, please please let me know.

Cheers,
Sergey

A colleague of mine just enlightened me (quote Lectora help file)

1. To show HTML published object names in the Properties window:
Select Preferences from the File menu. The Preferences window opens. Click the General tab if the Preferences window is not already opened to this tab.

2. Check the Show HTML published object names in object properties box.

3. Click OK.

Silly me

Awesome list Greg! Just a note for everyone. Flash player 10 has some added security "features" and for some reason if you try to grab a lectora variable and assign it to a variable in flash it will come back as undefined. So this call will fail:var tempVariable = ExternalInterface.call("Varvariablename.getValue()"); Even though it works great in flash players 8 and 9, as soon as someone upgrades to 10 that call will no longer work. Unless Adobe come out with an update for it.For now I've been working around it by adding an external HTML object to the page with a javascript function to set my flash variables. For example if in flash I had a variable called "setFromLectora" and I wanted to set it equal to a Lectora variable called "lectoraVariable" I would need external html that looked like:

<script>function setVars(){    var lectoraVariable = VarlectoraVariable.getValue();      window.document.swfanim2153.Se tVariable("setFromLectora",lectoraVariable); </script>

What this does is creates a javascript variable called lectoraVariable and sets it to the Lectora variable of the same name. Then it uses javascript to set that variable in the flash movie. swfanim2153 is the Lectora generated name of your flash movie. So inside of flash you would have something like:

var setFromLectora;ExternalInterface.call("setVars");

Anyhow, hopefully this will save a few headaches when your clients call and want to know why things stopped working when they upgraded to flash player 10.

hem99004,

how about the counterpart of your process.....lets just say we want your flash variable setFromLectora to be equal to a lectora variable (perhaps we will change the value of a lectora variable "AICC_Score" to the value of your flash variable "setFromLectora").

thanks anyway....
