Thank you for the updates and the post. I hope to update this page in the near future with more information about prototype, and to clarify this code.

Update. Checkboxes have a click method. This makes life even easier:

function(checkBox){ checkBox.click(); }

Just a tip, you’re adding some unnecessary conditionals to your anonymous function:

If you have the element already, then you could do this to make things faster.

function(checkBox){ checkBox.checked = !checkBox.checked }

However, this can be extended. If you have the id of a checkbox, you can use something that will get the checkbox for you.

function(elem_id){ $(elem_id).checked = !$(elem_id).checked }
