You want a hit test. This will compare the position of two rectangles (in your case) and say whether they overlap or not. Here's a simple one:
// given two rectangles: r1, r2 // x1, y1 is upper-left corner; x2, y2 is lower-right var hit = ( !(r1.x1 > r2.x2 || r1.x2 < r2.x1 || r1.y1 > r2.y2 || r1.y2 < r2.y1) ); - Richard On Dec 11, 2007 6:03 AM, Siemen Baader <[EMAIL PROTECTED]> wrote: > > Hi group, > > is there a way to detect if a draggable element is outside a given DOM > object when released?
