This provides for multiple levels of defense so that Anchors marked as disable actually behave as such.
Using this approach, you get an anchor that you cannot:
  - click
  - tab to and hit return
  - tabbing to it will move focus to the next focusable element
  - it is aware if the anchor is subsequently enabled

1.  Include this css, as it is the first line of defense.  This assumes the selector you use is 'a.disabled'
    a.disabled {
      pointer-events: none;
      cursor: default;
    }

 2. Next, instantiate this class such as (with optional selector):
    $ ->
      new AnchorDisabler()

class AnchorDisabler
  constructor: (selector = 'a.disabled') ->
    $(selector).click(@onClick).keyup(@onKeyup).focus(@onFocus)

  isStillDisabled: (ev) =>
    ### since disabled can be a class or an attribute, and it can be dynamically removed, always recheck on a watched event ###
    target = $(ev.target)
    return true if target.hasClass('disabled')
    return true if target.attr('disabled') is 'disabled'
    return false

  onFocus: (ev) =>
    ### if an attempt is made to focus on a disabled element, just move it along to the next focusable one. ###
    return unless @isStillDisabled(ev)

    focusables = $(':focusable')
    return unless focusables

    current = focusables.index(ev.target)
    next = (if focusables.eq(current + 1).length then focusables.eq(current + 1) else focusables.eq(0))

    next.focus() if next

  onClick: (ev) =>
    # disabled could be dynamically removed
    return unless @isStillDisabled(ev)

    ev.preventDefault()
    return false

  onKeyup: (ev) =>

    # 13 is the js key code for Enter, we are only interested in disabling that so get out fast
    code = ev.keyCode or ev.which
    return unless code is 13

    # disabled could be dynamically removed
    return unless @isStillDisabled(ev)

    ev.preventDefault()
    return false

$('html').on('click', 'a.Link', function(event){
    event.preventDefault();
});
