I am wondering if it is possible to have a dynamic counter
in a javascript function
I need to loop through that set of checkboxes, and check them or uncheck them. The checkboxes vary in amount and where on the page they start
I have the following code for this:
The problem is that there isn't always ten check boxes on the page , and also the loop does not always start at the first check box on the page. So I need to find a way to dynamically set the initialisation of the counter, and also the i<n number to loop through
eg:
to start at the fifth of ten check boxes:
needs to be set to: for(var i=5;i<10;i++)
to start at the eighth of seventeen check box
needs to be set to: for(var i=8;i<17;i++)
I would like to achieve this with the one function if possible
I already have the following code
(from this forum) to build a dynamic array:
Any help would be appreciated
