Finding checkboxesl between 2 checkboxes

[Mark]

Hi - I'm using asp.net to draw a grid (dates and people) which is
populated by checkboxes - each check box represents a day and a person
(so for example, I may have 2 weeks showing across the top, with 10
people showing down the side).

Currently, if I click on day 1 person 1, and I want to book their time
for 2 weeks, I have to manually check 14 checkboxes.

Is there a way for me to click on the first checkbox, and then click on
the last one, and have some javascript function populate all the
checkboxes in between?

Thanks for any help,

Mark

var firstCheckBox=... //save reference to checkboxes
var secondCheckBox=... //in this vars
var checkMode=false
var elements=document.forms[0].elements, item
for(var i=0;i<elements.length;i++){
item=elements[i]
if(item.type!='checkbox')continue
if(item==firstCheckBox) { checkMode=true; continue }
if(item==secondCheckBox) break
if(checkMode) item.checked=true
}
