Page loading spinner

• Press 1 to activate the demo
• Press 2 or Escape to deactivate the demo
• Press 3 to activate after 500ms

The full-page spinner doesn't cover the meganav by default.
Developers can override this with the additional class spinner--cover-all on the #section--content element.

Change demo to cover all

Test that it works with an alert message (press Escape to close).

In this example, we've added the spinner classes and the aria-busy attribute to the section containing the main page content (they are added automagically if they don't already exist).

<section id="section--content" class="section section--content spinner spinner--full-page" aria-busy="true">
    <h1>Page loading spinner</h1>
</section>

Toggle it with:

// @param {string} id = 'section--content'
UCASDesignFramework.spinners.activate(id)
UCASDesignFramework.spinners.deactivate(id)
// Waits 500ms before trying to activate if no other activation/deactivation commands received in the meantime.
UCASDesignFramework.spinners.activateAfterDelay(id)

Or use the global bus:

// @param {string} id = 'section--content'
UCASDesignFramework.bus.publish('df.spinner.activate', id)
UCASDesignFramework.bus.publish('df.spinner.deactivate', id)
// Waits 500ms before trying to activate if no other activation/deactivation commands received in the meantime.
UCASDesignFramework.bus.publish('df.spinner.activateAfterDelay', id)

And subscribe to activation/deactivation notices:

// @param {string} id = 'section--content'
var isActivatedSub = UCASDesignFramework.bus.subscribe('df.spinner.isActivated', function(id) {console.log('activated ' + id)})
var isDeactivatedSub = UCASDesignFramework.bus.subscribe('df.spinner.isDeactivated', function(id) {console.log('deactivated ' + id)})
