export default {
  name: 'SearchCascader',
  props: {
    defaultValue: {
      type: Array,
      default: () => []

      type: Function,
      default: () => ({})
    },
    isDisabled: {
      type: Boolean,
      default: false
    }
  },
  data() {
    return {
      dateValue:[],
      dataLists: [],
      key: ''
    }
  },
  watch:{
    defaultValue(val) {
      console.log(9999,val)
      this.key = Date.now()
      this.dateValue = val
    }
  },
  mounted() {

  },
  methods: {
    handleChange(val) {
      console.log(888,val)
      this.dateValue = val
      this.$refs.cascader.$refs.panel.clearCheckedNodes()
      this.$refs.cascader.$refs.panel.activePath = []
      this.$refs.cascader.$refs.panel.calculateCheckedNodePaths()
      this.action({ value: val, formId: this.formId })
    },
    handleSelect(item) {
      this.action({ value: item.value, formId: this.formId })
    }
  }
}
</script>

关键代码就三行

this.$refs.cascader.$refs.panel.clearCheckedNodes()
this.$refs.cascader.$refs.panel.activePath = []
this.$refs.cascader.$refs.panel.calculateCheckedNodePaths()
