Using REDIPS awesome drag and drop library I've been trying to work out why the droppedBefore event doesn't fire.
I've cut down bare bones example and uploaded the files here for an easy repro: http://tempsend.com/8B0DF444D3 and here is a live snippet to show you the issue quickly.
"use strict";
// define redips_init variable
var redips = {}, // redips container
rd = REDIPS.drag, // reference to the REDIPS.drag library
msg;
// redips initialization
redips.init = function () {
msg = document.getElementById('message');
// how to display disabled elements
rd.style.borderDisabled = 'solid'; // border style for disabled element will not be changed (default is dotted)
rd.style.opacityDisabled = 60; // disabled elements will have opacity effect
// initialization
rd.init();
// only "smile" can be placed to the marked cell
//rd.mark.exception.d8 = 'smile';
// shift DIV elements with animation
rd.shift.animation = true;
// disabled elements will have opacity effect
rd.style.opacityDisabled = 50;
// set hover color
rd.hover.colorTd = '#9BB3DA';
// prepare handlers
rd.event.cloned = function () {
// display message
var pos = rd.getPosition();
msg.innerHTML += ' FROM ' + pos[1] + ' ' + pos[2] + '<br>'
};
rd.event.droppedBefore = function (targetCell) {
alert('THIS EVENT FIRED YAY@!!!!'); //<-- SHOW THIS TO WIN THE PRIZE!
};
rd.event.deleted = function (cloned) {
// if cloned element is directly moved to the trash
if (cloned) {
var pos = rd.getPosition();
msg.innerHTML += ' TO ' + pos[1] + ' ' + pos[2] + '<br>';
}
else {
msg.innerHTML += 'Deleted';
}
};
};
// add onload event listener
if (window.addEventListener) {
window.addEventListener('load', redips.init, false);
}
else if (window.attachEvent) {
window.attachEvent('onload', redips.init);

</body></html>To see the problem Run Code Snippet and drag a box onto another box, an alert should be shown saying: THIS EVENT FIRED YAY@!!!!
I've taken the above code from http://www.redips.net/my/preview/REDIPS_drag/example26/ which has a working rd.event.droppedBefore event. I've compared my cut down repro with the example 10 times over and still can't determine why the event isn't being fired? The other 2 events rd.event.cloned and rd.event.deleted both work.
