Using load() in a page to add other html to page.

Using load() in a page to add other html to page.

I am creating a project that is HTML and JQuery/Javascript only. I have used the load() and it does show up on the page. However the added page uses a javascript or javascripts files that are loaded on the index page. It appears that the added page cannot use the loaded script. It works fine if i use it on the index page directly. I am only using div tags with special objects in the tag that the javascript looks for. 

Am i to assume that when you load() a page into another it really isn't part of the page? I am used to using scripting like C# or even PHP/Zend that you just add the pages and it utilizes all the css and javascript files like it is one page. 

Thanks for your help.
