Knockoutjs
A simple group checkbox for Knockout.js
I’ve been using Knockout for the first time on a new project and have been pretty impressed. Recently, I had a need to implement a simple ‘group checkbox’. The Knockout documentation already provided an example of a ‘select / deselect all’ checkbox, but the behaviour I wanted was slightly different. I wanted a checkbox that would be unchecked when its children were disabled, checked when any were enabled and would select / deselect all if I toggled it. With a little research into ‘computed properties’, it turned out this is quite easy to do.
