填坑处理:
1、用户未输入搜索关键词时,mescroll不能就直接初始话,要在用户输入的时候才能初始化,所以子组件就接受了父组件的keyword,并用
v-if="keyword !== ''"来判断加载子组件的条件,然后子组件通过监听keyword的变化,重置mescroll:如下:
watch: {
        'searchName' () {
            this.dataList = [];//要清空,不然有时候会出现上拉加载不了
            this.searchName !== '' && this.mescroll.resetUpScroll();
        }
    },

  2、搜索完以后点击搜索输入框右边里的关闭按钮,发现其他列表不能滑动。解决方法:要加:isBounce: true,
