watch改成如下：

watch: {
    value() {
      this.valueId = this.value;
      this.initHandle();
    },
    options: {
      handler(newValue, oldValue) {
        this.valueId = this.value;
        this.initHandle();
      },
      deep: true
    }
  },

methods 里面 initHandle函数改成如下：

// 初始化值
    initHandle() {
      if (this.valueId) {
        this.$nextTick(() => {
          let node = this.$refs.selectTree.getNode(this.valueId);
          if (node != null) {
            this.valueTitle = node.data[this.props.label]; // 初始化显示
            this.$refs.selectTree.setCurrentKey(this.valueId); // 设置默认选中
            this.defaultExpandedKey = [this.valueId]; // 设置默认展开
          }
        });
      } else {
        this.valueTitle = ""; // 清除缓存显示
      }
      this.initScroll();
    },
