[3.0.4] Javascript On Demand with HeadJS

Checkout index.html with this example bellow.

We depend of HeadJS library to to do our magic, so add it and out function just into head of your html.

	<script src="assets/vendor/headjs/dist/1.0.0/head.load.min.js"></script>
	<script src="lib/app.js"></script>

After it, you nee to create an instance of the App function.

The App function can receive the following params during its instantiation:

var app = {
  protocol : "",
  host : "localhost",
  // You can define default instances or vendors to load in every page filling this next parameters
  instances : [],
  vendors : []
};
 
3. In each page of your site, you can define those scripts to load or call by instances, like this:

>Instance will run after each vendor defined on current page.
```javascript
app.setInstances([
   "myMenuPlugin();",
   "AnotherFormValidation();"
]);
 
app.setVendors([
   'https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js'
]);

each vendor entry URL, if it isn't a valid URL, is adjusted to a complete URL, so 'assets/js/main.js' will be transformed to 'http://localhost/assets/js/main.js'

At least, if you have a footer that repeats in everything, put it there just before the </body>.

This code will load every instance and vendor that you had set.

if (typeof head === 'function' && typeof App === 'function' && typeof app !== 'undefined') {
	head.load(app.getVendors(), function() {
		console.table(app.getVendors());
	});
}
