[web] Check all check boxes when one is checked and then uncheck when it's not.
Author
I wrote a javascript function that is suppose to check all check boxes in a list when the main check box is checked then when it's unchecked it unchecks all of the check boxes in the list. The problem is that the code I wrote only seems to check the boxes not uncheck them... I'm calling the function when the onclick event occurs.
Here is the source:
I may be a little bit rusty at javascript but it looks like you have it backwards. When all the elements should be checked it is setting them to false (if .checked == true ... i.checked = false) and when all elements should be unchecked it is setting them to true. Try flipping your true and false assignments.
