When loading an html page via ajax, will script tags be loaded?

Question

When you load an html document using AJAX, what does it do with the nodes inside the HEAD tag: (script,link,style,meta,title) ignore them or load and parse them? And in the

Answer 1

When you say "load" I understand that to merely mean invoking XHR (or $.ajax or $.get etc) to pull down an XML, JSON, or text resource from a web server, store it in the browser's JS runtime memory, and get a reference to it. For HTML resources, that act alone doesn't parse anything.

However, if you take that HTML and inject it into the DOM (at least in Firefox 3.5), then it will be interpreted. For example, say you had the following three, very professional files.

barf1.html:

    
        
        
    
    
        long live barf1!
    

barf2.html:

    
    
    barf2 lives here now!

barf3.js:

alert('barf3!');

When you navigate to barf1.html, the page content will change, and you will see two JavaScript alerts, indicating that both inline script blocks and external script files are interpreted.
