I am using Sortable.js and Vue.js. The goal is to sort items and keep data updated.
It worked well with Vue 1.x, but after update to 2.0 sorting became incorrect. Array still properly updates, but items in DOM are in the wrong places.
new Vue({
el: '#app',
template: '#sort',
data: function() {
return {
items: [
"",
"",
"",
""
],
}
},
mounted: function() {
this.$nextTick(function () {
Sortable.create(document.getElementById('sortable'), {
animation: 200,
onUpdate: this.reorder.bind(this),
});
})
},
methods: {
reorder: function(event) {
var oldIndex = event.oldIndex,
newIndex = event.newIndex;
this.items.splice(newIndex, 0, this.items.splice(oldIndex, 1)[0]);
}
}
});
jsFiddle /
Can someone help me?

Both seem to be have an inpatibility when the DOM is modified.The only possible "patch" I see is to use 2 arrays, 1 for painting and the other to keep track of changes – ragnar Commented Oct 5, 2016 at 8:52

Reset to default 6I had a similar problem today.
Add :key value to make sure Vue rerenders elements in correct order after Sortable changes the items order
<div v-for="item in items" :key="item.id">
<!-- content -->
</div>
https://v2.vuejs/v2/guide/list.html#key
As it happens, Sortable keeps track of the order in sortable.toArray(), so it's pretty easy to make a puted that will give you the items in sorted order, while the original item list is unchanged.
new Vue({
el: '#app',
template: '#sort',
data: {
items: [
"http://placehold.it/200X300?text=image1",
"http://placehold.it/200X300?text=image2",
"http://placehold.it/200X300?text=image3",
"http://placehold.it/200X300?text=image4"
],
order: null
},
puted: {
sortedItems: function() {
if (!this.order) {
return this.items;
}
return this.order.map((i) => this.items[i]);
}
},
mounted: function() {
this.$nextTick(() => {
const sortable = Sortable.create(document.getElementById('sortable'), {
animation: 200,
onUpdate: () => { this.order = sortable.toArray(); }
});
})
}
});<script src="//cdnjs.cloudflare./ajax/libs/Sortable/1.4.2/Sortable.min.js"></script>
<link href="//maxcdn.bootstrapcdn./bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<script src="//unpkg./[email protected]/dist/vue.js"></script>
<div id='app'></div>
<template id="sort">
<div class="container">
<div class="row sort-wrap" id="sortable">
<div class="col-xs-6 col-md-3 thumbnail" v-for="(item, index) in items" :data-id="index">
<img v-bind:src="item" alt="" class="img-responsive">
</div>
</div>
<div v-for="item in sortedItems">
{{item}}
</div>
</div>
</template>Make sure you aren't using a prop, or you won't be able to sort. If you are using a prop, assign the prop data to a data attribute and use the data attribute instead.
