This was downright difficult. The good news is that the code got a little shorter, the HTML is a LOT shorter, the menu settings are in a shorter config file, and the direct manipulation of the DOM has reduced significantly.
When the user clicks on a menu item, here's what happened:
The original scanned the DOM to toggle off the current item. Then toggled the new item.
Now, the new version maintains a copy of the menu configuration, and alters this model. A loop scans the model and sets a "selected" bit, then triggers the animations.
I've made may first directive! OK, not that special, but to me it is. This is one of the more difficult features I've come across in Angular, and I still don't really "get it".
I'm not even going to do a code walkthrough, because I can't really explain it well. The easy part is calculating the height the element should be. The tricky part is implementation.
This is one of those "why bother with an external library" moments. Mostly copied from MDN.
Mobile websites all seem to have this button, which appears when you've scrolled down a bit. The button scrolls you back to the top of the page, where most of the menus reside.
I almost wrote a page for this, but it turns out a bookmarklet is good enough:
All the tutorials out there teach JS by having the user write a file, and load it into the browser.
I was thinking a bit about the JS co-learning thing, and discovered that services, APIs and libraries really change the game, or have changed the game.
Prelims: HTML and DOM CSS and DOM
The attached file is a rudimentary demonstration of persistent local storage in the browser. You can click on it to see the page in action, and do a view source on that page.
I was reading the code at iworkfortheinternet.org and learned how to do this "scrolling forever wall" effect. It's clever.
HTML 5 is a marketing term (kind of like "cloud computing") that has a somewhat imprecise technical meaning, but was created so that products and people could easily sum up their compatibility or know
A ten second calculation to deter comment spam. It's an old technique called "hash cash" and has nothing to do with drugs.
It's hard to concentrate when you're tired and cranky, so I wasted some time writing a simple calculator in several different languages.
