Custom Click Validator
Custom Click Validator
This example demonstrates how to implement a custom click validator to
make a circular drag and drop implementation. Because all DOM elements that
have dimensions are rectangular, the way to implement a circular drag object
is to perform calculations on mousedown to determine whether the mouse was
targeting a valid portion of the element (eg, a portion within the circle).
The same method could be used to create any non-rectangular draggable object.
