Javascript <script> inside PHP echo : won't execute

Question

I have a weird issue with a javascript script that won't run inside my php echo. The script shows in the source page but doesn't run. My file is in a iframe (facebook app), I am using firefox and firebug.

I have a function returning my script as a string, and then I echo this function.

function myFunction($request_token){
    if ($count == 0){
        return "<script>console.log(\"run??\");</script><a href=\"blabla\"></a>";
    }
}

When I look at the source code I see

<script>
    console.log("run??");
</script>
<a href="blabla"></a>

which seems fine, but nothing shows up in the console. I tried to do an alert, won't work either.

Does somebody have an idea?

Try <script type="text/javascript">. Do you have any other scripts on the page that might throw errors? (scripts are executed in serial, if one throws you're done). — Halcyon

I tried to add text/javascript, doesn't work either. I have other scripts + the facebook scripts, but no error shows up in the console — nax_

Have you tried changing <script> to <script type="text/javascript">?

Does this help if I say that I load my file with the echo from javascript like that : xmlhttp.open("GET","php/myFile.php?request=init,true); xmlhttp.send(); Then in myFile.php I echo myFunction

@nax_ - So you have a page that uses JavaScript to use AJAX to call a a PHP page to return JavaScript?

Yes I do. Sounds stupid now that you say it but yeah that's how it works. By the way, as you might have guessed xmlhttp is a XMLHttpRequest()
