Check differently named checkboxes

[jamesboulter]

Dear all,

I can find plenty of functions that check all checkboxes with a certain
HTML "name" attribute, but on the page in question, each is named
slightly differently:

Therapy_1
Therapy_2
Therapy_3
etc.

Perhaps someone could advise how the increasing number could be
incorporated into the Javascript and hence each of the boxes be ticked?

Many thanks in advance,
James Boulter

Check out my "Checkbox Group" library at:
http://www.javascripttoolbox.com/checkboxgroup/

It allows you to group boxes together using wild cards, such as "Therapy_*"
under a master control box.

Otherwise, you can manually loop through all form inputs and check their
name with:
if (obj.name.indexOf("Therapy_")==0) { obj.checked=true; }

Thanks Matt, that's a great solution - now using your script!
Being very ignorant of Javascript, I'd missed the "*" solution!

Cheers,
