对象或者数组的监听

watch: {
		    bufferInfoList: {
		      handler(newValue, oldValue) {
		        // console.log("newValue", newValue);
		      },
		      immediate: true,
		      deep: true
		    }
  },
  computed: {
    bufferInfoList() {
      // console.log(
      //   "这是this.$parent.bufferInfos111111111111111111111111111111111111",
      //   this.$parent.bufferInfos
      // );
      return this.$parent.bufferInfos;
    }

普通格式数据的监听

watch: {
			    bufferInfoList(newVal,oldVal){
			    	console.log('这是val',val);
			    }
      }
