//手释放，如果在500毫秒内就释放，则取消长按事件，此时可以执行onclick应该执行的事件

              isDisabled === true?' disabled ':'',
              ]"

对应的样式去掉 scoped

// 声明一个全局变量
let that;
// 在生命周期 beforeCreate里面改变this指向
beforeCreate: function () {
     that = this;
},
filters:{
  timeFilter(val){
      let data = that.time;
      return data;
  }
},

加个watch

watch: {
    dataSource: {
      immediate: true,
      handler (val) {
          // TODO
      }
    }
  }
