JavaScript: Including content?

Hey guys,

I’ve never used javascript before. I’m doing a design for a client who wants to stay on his current server. His server is VERY basic and doesn’t support PHP. I usually include content (like the navigation) using PHP. That way I don’t have to change every single page if he wants the nav changing.

Now, since I could use PHP to include, I’m guessing I have to use JavaScript…

Can someone help me out? I’m extremely new to this.

Thanks guys!

Ben
