What would you like to do? - disable links once and for all with a.disabled or the disabled attribute
class AnchorDisabler
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()
constructor: (selector = 'a.disabled') ->
isStillDisabled: (ev) =>
### since disabled can be a class or an attribute, and it can be dynamically removed, always recheck on a watched event ###
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(
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)
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)
return false
