base.litcoffee
¶

The Base class contains common methods that are mixed in to the contoller and view

It has some dependencies:
```
capitalize = require 'underscore.string/capitalize'

methods =
```

Attempts to call the method ‘onChangeFromPreviousSizeToNewSize’ to handle responsive events, i.e. onChangeFromLargeToSmall

  onResolutionChanged: (resolution) ->

    @currentResolution = resolution.newSize

    methodName = "onChangeFrom#{capitalize(resolution.prevSize)}To#{capitalize(resolution.newSize)}"

    try
        this[methodName]()
    return

Checks to see if the given element is substantially in the viewport. Returns the height of visible portion of the element.
```
  inViewport: (el) ->

    return 0 unless $(el).length

    elBounds = $(el).get(0).getBoundingClientRect()
```

the el is not visible

    return 0 if elBounds.bottom <= 0 or elBounds.top >= window.innerHeight

the el is entirely visible

    return $(el).height() if elBounds.top >= 0 and elBounds.bottom <= window.innerHeight

if the el’s top is visible but not the bottom

    if elBounds.top >= 0 and elBounds.bottom >= window.innerHeight
        return $(el).height() - (elBounds.bottom - window.innerHeight)

if the el’s bottom is visible but not the top

    if elBounds.bottom < window.innerHeight and elBounds.top < 0
        return $(el).height() - (elBounds.top * -1)

the el is filling the entire window

    return $(el).height() if elBounds.top <= 0 and elBounds.bottom >= window.innerHeight
