Html_Template_Flexy and JavaScript

Hi, I'm trying to use some flexy vars in Javascript functions and the replacement doesn't occurs. I suppose It's caused by the comments "<!-- ... -->" inside the <script> tag. Of course if I remove comments flexy complains about this ugly practice ;-) Is there an easy way to make flexy replacements in js functions ?? I've seen in 6.0 change log : <flexy:toJavascript flexy:prefix="js_name_prefix_" jsvar="php_flexy_var" ....> uses HTML_Javascript_Convert to import PHP variables into Javascript. Is this my problem's solution ? How can I use it in functions ? Thanks for any help.
