Part 2: The right way to inject JavaScript? - Wikitech-l

8 Jan 2016

Last week, I asked the right way to inject raw JavaScript so that "mw" and
"jQuery" were defined. I was helpfully pointed to
ResourceLoader::makeInlineScript(), which wraps the JS in the appropriate magic:

	https://lists.wikimedia.org/pipermail/wikitech-l/2015-December/084408.html

Now, what is the right way to include a remote JavaScript file? If I simply use
OutputPage::addScript() like this:

	$myOutputPage->addScript('<script
src="http://remote.com/myfile.js"></script>')

it fails because the remote JavaScript file references the "jQuery" object like
this:

	 function ($) {
		//... code here
	}(jQuery));

I get "ReferenceError: jQuery is not defined" on the last line.  I guess the
remote script is getting evaluated before ResourceLoader brings in jquery.js...?

Thanks very much for any advice.
