javascript - Changing DOM order after drag and drop with packey and draggabilly -

-

itemprop = "text">

There is a bug on this code 

  docReady (function (); On top pckry = new packery (slidesElem, {rowHyight: slideSize.outerHeight}); / varSelector ('slide.'); SlideSize = getSize (document.querySelector ('Slide.')); / Item items on itemElems = pckry.getItemElements (); // for each item (for example, I = 0 lane = itemElems.length; I & lt; lane; i ++) {var = ItemElems [i]; // Elements Draggabilly draggie with draggie to make = Draggabilly (ELEM, {axis: 'y'}); // Packery pckry.bindDraggabillyEvents (draggie) bound to draggabilly events;} // Once again the item is in the position after the dom pckry.on ('dragItemPositioned', function (_pckry, draggedItem) {var index = pckry.items.indexOf (draggedItem); nextItem = pckry.items [index + 1] ; SlidesElem.inser first (dragged itam.lim, next etam.liment);});});

When I drag the "first" item to "last", the DOM does not change and the error appears in the console.

Any thoughts? I'm really struggling to find the error.

I appreciate all your help

using the sample:

You do not need to change the index, it should be just 

  on nextItem = pckry.items [index];

dragged item returns to the index where you put it / where the next item

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
