	   <el-form ref="form" :model="form" :rules="rules" label-width="80px">
	     <div id="sortId">
	        <div data-id="1">item 1</div>

export default {
  name: "searchSort",
  components: {
    Sortable
  },
  data() {
    return {
    	open:false,
      	//类型：1.记账页面
      	type: undefined,
    };
  },
  created() {
  },
  methods: {
    init(type) {
    	this.type = type;
    	this.open=true;
	    this.$nextTick(function(){
	       var el = document.getElementById('sortId');
	      //设置配置
	      var ops = {
	        animation: 1000,
	        //拖动结束
	        onEnd: function (evt) {
	          console.log(evt);
	          //获取拖动后的排序
	          var arr = sortable.toArray();//输出的值是data-id的值
	          alert('获取拖动后的排序'+ JSON.stringify(arr));
	        },
	      };
	      //初始化
	      var sortable = Sortable.create(el, ops);
	  })
    },
    cancel(){
		this.open=false;
	},
	submitForm(){

4.总结

a.如果多个页面调用该页面出现无法拖动的情况，把sortId做成动态的。
如：

<div :id="dtId"></div>
<script>
data() {
  	return {
		dtId:'sortId'
	}
	methods: {
	    init(type) {
	    	var el = document.getElementById(this.dtId);
	    }
    }
}
</script>
