如何保存排序顺序？

Question

我已经使用packery和draggabilly 创建了Demo,我有五个网格.我可以使用draggable对它们进行排序.我进行排序.我需要保存排序的网格.当我在dev中检查时,网格没有移动位置正在改变而不是网格.

因为我已经通过了ID,但没有用.由于上面提到的问题.

有没有办法保存排序顺序？我不想用localStorage

我的代码如下

HTML

<h1>Image sort</h1>
<div class="packery">
  <div class="item w2 h2 i1" tabindex="0">A</div>
  <div class="item w2 h2 i2" tabindex="1">B</div>
  <div class="item w2 h2 i3" tabindex="2">C</div>
  <div class="item w2 h2 i4" tabindex="3">D</div>
  <div class="item w2 h2 i5" tabindex="4">E</div>
</div>

JS

// http://packery.metafizzy.co/packery.pkgd.js and 
// http://draggabilly.desandro.com/draggabilly.pkgd.js added as external resource

// ----- text helper ----- //

$(function() {

  var $container = $('.packery').packery({
    columnWidth: 100,
    rowHeight: 180,
    // disable initial layout
    isInitLayout: false
  });

  var pckry = $container.data('packery');


  // ----- packery setup ----- //

  // trigger initial layout
  $container.packery();

  var itemElems = $container.packery('getItemElements');
  // for each item element
  $( itemElems ).each( function( i, itemElem ) {
    // make element draggable with Draggabilly
    var draggie = new Draggabilly( itemElem );
    // bind Draggabilly events to Packery
    $container.packery( 'bindDraggabillyEvents', draggie );
  });   

CSS

* {
  -webkit-box-sizing: border-box;
     -moz-box-sizing: border-box;
          box-sizing: border-box;
}

body { font-family: sans-serif; }

.packery {
  background: #FDD;
  background: hsla(45, 100%, 40%, 0.2);
  max-width: 460px;
}

/* clearfix */
.packery:after {
  content: ' ';
  display: block;
  clear: both;
}

.item {
  width: 240px;
  height: 140px;
  float: left;
  background: #C09;
  border: 4px solid #333;
  border-color: hsla(0, 0%, 0%, 0.3);
  font-size: 20px;
  color: white;
  padding: 10px;
}

.item:hover {
  border-color: white;
  cursor: move;
}


.item.w2 { width:   400px;  }
.item.h2 { height:  140px;  }

.item.w2.i1 { background: #ffff00; }
.item.w2.i2 { background: #ff6633; }
.item.w2.i3 { background: #00c6d7; }
.item.w2.i4 { background: #990099; }
.item.w2.i5 { background: #EEEEEE; }

.item.is-dragging,
.item.is-positioning-post-drag {
  border-color: white;
  background: #09F;
  z-index: 2;
}

发现这个codepen看起来与您的示例非常相似。

Packery.prototype.sortItems = function( keys, getSortKey ) {
  // copy items
  //var _items = this.items.slice(0);
  var itemsBySortKey = {};
  var key, item;
  for ( var i=0, len = this.items.length; i < len; i++ ) {
    item = this.items[i];
    key = getSortKey( item );
    itemsBySortKey[ key ] = item;
  }

  i=0;
  len = keys.length;
  var sortedItems = [];
  for ( ; i < len; i++ ) {
    key = keys[i];
    item = itemsBySortKey[ key ];
    this.items[i] = item;
  }  
};

var storedSortOrder = localStorage.getItem('sortOrder')
if ( storedSortOrder ) {
  storedSortOrder = JSON.parse( storedSortOrder );
  pckry.sortItems( storedSortOrder, function( item ) {
    return item.element.getAttribute('tabindex');
  });
}
