<template>
<treeselect ref="DRHA_EFaultModeTree"
    v-model="DRHA_EFaultModeTree_value"
    :multiple="true" 
    :options="DRHA_EFaultModeTree_options"
    :flat="true"
    :show-count="true"
    :disable-branch-nodes="true"
    :searchable="false"
    @select="DRHA_EFaultModeTree_handleSelect"
    @deselect="DRHA_EFaultModeTree_handleDeSelect"
    placeholder=" 请选择..."/>
 <p>lables：{{DRHA_EFaultModeTree_lables}}</p>
 <p>ids:{{DRHA_EFaultModeTree_value}}</p>
</template>
<script>
 // import the component
 import Treeselect from '@riophae/vue-treeselect'
 // import the styles
 import '@riophae/vue-treeselect/dist/vue-treeselect.css'
 export default {
 components: { Treeselect },
 data() {
  return {
  DRHA_EFaultModeTree_value: null,
  DRHA_EFaultModeTree_lables: [],
  DRHA_EFaultModeTree_options: [ {
   id: '1',
   label: 'Fruits',
   children: [ {
   id: '1-1',
   label: 'Apple ?',
   isNew: true,
   }, {
   id: '1-2',
   label: 'Grapes ?',
   }, {
   id: '1-3',
   label: 'Pear ?',
   }, {
   id: '1-4',
   label: 'Strawberry ?',
   }, {
   id: 'watermelon',
   label: 'Watermelon ?',
   } ],
  }, {
   id: 'vegetables',
   label: 'Vegetables',
   children: [ {
   id: 'corn',
   label: 'Corn ?',
   }, {
   id: 'carrot',
   label: 'Carrot ?',
   }, {
   id: 'eggplant',
   label: 'Eggplant ?',
   }, {
   id: 'tomato',
   label: 'Tomato ?',
   } ],
  } ],
  };
 },
 mounted: function(){
 },
 methods: {
  DRHA_EFaultModeTree_handleSelect(node,instanceId){
  console.log("Select");
  this.DRHA_EFaultModeTree_lables.push(node.label);
  },
  DRHA_EFaultModeTree_handleDeSelect(node,instanceId){
  console.log("DeSelect");
  for (let i = 0;i<this.DRHA_EFaultModeTree_lables.length;i++){
   if(node.label == this.DRHA_EFaultModeTree_lables[i]){
   this.DRHA_EFaultModeTree_lables.splice(i,1);
   }
  }
  },
 }
 };
