I thought about an approach that checked all the boxes then cleared the ones
following the checked one by using selectors and DOM navigation, but I think
it's much simpler to do an each() instead.
$(document).ready(function(){
$("#myform checkbox").bind("click", function(){
var mybox = this;
var tick = true;
$("myform checkbox").each(function(){
this.checked = tick;
if ( this == mybox )
tick = false;
});
});
});
