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
