Hi
I am using this.
new Draggable('hueArrows',{
snap: function(x,y,draggable) {
function constrain(n, lower, upper) {
if (n > upper) return upper;
else if (n < lower) return lower;
else return n;
}
element_dimensions =
Element.getDimensions(draggable.element);
parent_dimensions =
Element.getDimensions(draggable.element.parentNode);
return[
constrain(x, 0, parent_dimensions.width
-
element_dimensions.width),
constrain(y, 0,
parent_dimensions.height -
element_dimensions.height)];
},
revert:false
});
When dragging, I want to read the position of "hueArrows" and take
some actions. How can I do this?
Regards,
Moe Sweet
