一、安装依赖
npm install vuedraggable --save
npm insall sortablejs --save
二、引入依赖
import draggable from 'vuedraggable'
import Sortable from 'sortablejs'
三、JS函数拖动改变顺序（数组）：
drag(){
let newArr=this.checkMaterial.join(',');
let el = document.getElementById('items');
//let sortable = Sortable.create(el);
let that=this;
Sortable.create(el,{
group: newArr,
store: {
//获取初始的数组
get: function (sortable) {
// console.log(sortable.options.group.name)
let order = sessionStorage.getItem(sortable.options.group.name);
return order ? order.split(',') : [];
},
//获取排序之后的数组
set: function (sortable) {
var order = sortable.toArray();
sessionStorage.setItem(sortable.options.group.name, order.join(','));
that.checkMaterial=order;
}
}
})
}
