You shouldn't have to depend on CDNs as there's no guarantee they'll be up all of the time. I usualayy have a local fallback that can be triggered in this way: !window.jQuery && document.write(unescape('%3Cscript src="/js/jquery-1.4.2.min.js"%3E%3C/script%3E')) The second script looks for the jQuery global object that should exist after the CDN fetch. If it doesn't exist, it knows to get your own copy. (If you're won…
Have you tested that to make sure that it blocks on the first script tag in every browser? Over the internet (as opposed to on your dev box), I'd expect that to always evaluate to false and therefore include your local script. You might want to look into putting that call into window.onload so that it does what you think it does.
You will almost definitely have scripts that you have included after these two that depend on the jQuery object existing (otherwise what's the point in having jQuery at all). So imagine this trick wasn't used, and you just served up a local (or CDN hosted) copy of jQuery, then started using it in later scripts. It's reasonable at that point to assume that jQuery exists - which is because each script blocks, or if it doesn't, the browser itself will still make sure they execute in order. So it's perfectly safe to use this script without worrying about the order of things.
This is exactly why I (and many others) suggest that you put all of your tags at the bottom of the element. They block page rendering, so if they're in the , or dotted around the , they're going to delay the presentation of the page to the visitor.
