import sortable deletable code
I’ve grabbed the relevant code from the sortable deletable branch @MacNCheese created, and pulled it into the latest version of meteoric. Hoping to get it to a PR-able state.

Slip - swiping and reordering in lists of elements on touch screens, no fuss.
|
||||
|
||||
Fires these events on list elements:
|
||||
|
||||
• slip:swipe
|
||||
When swipe has been done and user has lifted finger off the screen.
|
||||
If you execute event.preventDefault() the element will be animated back to original position.
|
||||
Otherwise it will be animated off the list and set to display:none.
|
||||
|
||||
• slip:beforeswipe
|
||||
Fired before first swipe movement starts.
|
||||
If you execute event.preventDefault() then element will not move at all.
|
||||
|
||||
• slip:reorder
|
||||
Element has been dropped in new location. event.detail contains the location:
|
||||
• insertBefore: DOM node before which element has been dropped (null is the end of the list). Use with node.insertBefore().
|
||||
• spliceIndex: Index of element before which current element has been dropped, not counting the element iself.
|
||||
For use with Array.splice() if the list is reflecting objects in some array.
|
||||
|
||||
• slip:beforereorder
|
||||
When reordering movement starts.
|
||||
Element being reordered gets class `slip-reordering`.
|
||||
If you execute event.preventDefault() then element will not move at all.
|
||||
|
||||
• slip:beforewait
|
||||
If you execute event.preventDefault() then reordering will begin immediately, blocking ability to scroll the page.
|
||||
|
||||
• slip:tap
|
||||
When element was tapped without being swiped/reordered.
|
||||
|
||||
• slip:cancelswipe
|
||||
Fired when the user stops dragging and the element returns to its original position.
|
||||
|
||||
|
||||
Usage:
|
||||
|
||||
CSS:
|
||||
You should set `user-select:none` (and WebKit prefixes, sigh) on list elements,
|
||||
otherwise unstoppable and glitchy text selection in iOS will get in the way.
|
||||
|
||||
You should set `overflow-x: hidden` on the container or body to prevent horizontal scrollbar
|
||||
appearing when elements are swiped off the list.
|
||||
|
||||
|
||||
var list = document.querySelector('ul#slippylist');
|
||||
new Slip(list);
|
||||
|
||||
list.addEventListener('slip:beforeswipe', function(e) {
|
||||
if (shouldNotSwipe(e.target)) e.preventDefault();
|
||||
});
|
||||
|
||||
list.addEventListener('slip:swipe', function(e) {
|
||||
// e.target swiped
|
||||
if (thatWasSwipeToRemove) {
|
||||
e.target.parentNode.removeChild(e.target);
|
||||
} else {
|
||||
e.preventDefault(); // will animate back to original position
|
||||
}
|
||||
});
|
||||
|
||||
list.addEventListener('slip:beforereorder', function(e) {
|
||||
if (shouldNotReorder(e.target)) e.preventDefault();
|
||||
});
|
||||
|
||||
list.addEventListener('slip:reorder', function(e) {
|
||||
// e.target reordered.
|
||||
if (reorderedOK) {
|
||||
e.target.parentNode.insertBefore(e.target, e.detail.insertBefore);
|
||||
} else {
|
||||
e.preventDefault();
|
||||
}
|
||||
});
|
||||
|
||||
Requires:
|
||||
• Touch events
|
||||
• CSS transforms
|
||||
• Function.bind()
|
||||
|
||||
Caveats:
|
||||
• Elements must not change size while reordering or swiping takes place (otherwise it will be visually out of sync)
