Quick Dojo Setup Snippet for MooTools Developers

By  on  

We're all used to aliasing methods within our favorite JavaScript frameworks. For example, you'll see the following pattern within jQuery:

(function($) {
	//your jQuery here, referenced by $
})(jQuery);

You may also see the following pattern within MooTools code:

(function($) {
	//your MooTools here, referenced by $
})(document.id);

Within the Dojo community I frequently see the following pattern:

;(function(d, $) {
	//your dojo here, selector engine referenced by $
})(dojo, dojo.query);

I love that pattern but I've created my own that I think will be a bit easier for MooTools developers looking to use Dojo:

;(function(d, $, $$) {
	//your dojo here
	//byId referenced by $
	//selector engine referenced by $$
})(dojo, dojo.byId, dojo.query);

While the $$ method is unique to MooTools, Dojo features both a byId method to get a single node and a query method to retrieve multiple nodes. You could just as easily retrieve one element with dojo.query but I like the security (and speed) that associating $ with byId gives me.

    Create Namespaced Classes with MooTools

    MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does.  Many developers create their classes as globals which is generally frowned up.  I mostly disagree with that stance, but each to their own.  In any event...

    One major gripe that we've always had about CSS is that creating layouts seems to be more difficult than it should be. We have, of course, adapted and mastered the techniques for creating layouts, but there's no shaking the feeling that there should be a...

    Image Reflections with CSS

    Image reflection is a great way to subtly spice up an image.  The first method of creating these reflections was baking them right into the images themselves.  Within the past few years, we've introduced JavaScript strategies and CANVAS alternatives to achieve image reflections without...

    Wonderful, Mr Walsh!

    Man, sorry to bother, but why did you change the layout of the Code? Now is almost illegible.

    (Sorry if I have bad English, I’m kinda rusty)

  3. David Walsh

    @CarlitoS: Not sure what you mean.

  4. Joe

    What’s with the semicolon in the front of the last two code snippets?

  5. David Walsh

    @Joe: It’s a built-in safety for if there’s no “;” on the previous line. Learned that from Dojo Lead Pete Higgins.

  6. CarlitoS

    What I meant was that earlier you used to have the code inbetween frames with gray backround. Now the code is over white background and the font color is like gray 35%. Also the size looks like 4 points, I wear glasses but still is hard to read it. Thanks!

  7. David Walsh

    @CarlitoS: Ahhh, the comments in the syntax highlighter. I’ll address that soon.
