Vue中二次封装better-scroll插件

1.用npm 安装好 better-scroll

npm install--save better-scroll

2.新建公共组件scroll

<template>
  <div ref="wrapper">
    <slot></slot>
  </div>
</template>

<script type="text/ecmascript-6">
import BScroll from 'better-scroll';

export default {
  name: 'scrollComm',
  props: {
    probeType: {
      type: Number,
      default: 1
    },
    click: {
      type: Boolean,
      default: true
    },
    //scroll 通常会有循环的数组对象
    data: { 
      type: Array,
      default: null
    },
    // 监听
    listenScroll: {
      type: Boolean,
      default: false
    },
    // 是否需要上啦刷新
    pullup: {
      type: Boolean,
      default: false
    },
    // 处理移动端 input输入时在滚动列表 键盘不回收起问题
    beforeScroll: {
      type: Boolean,
      default: false
    },
    refreshDelay: {
      type: Number,
      default: 20
    }
  },
  mounted() {
    setTimeout(() => {
      // eslint-disable-next-line
      this._initScroll();
    }, 20);
  },
  methods: {
    _initScroll() {
      if (!this.$refs.wrapper) {
        return;
      }
      this.scroll = new BScroll(this.$refs.wrapper, {
        probeType: this.probeType,
        click: this.click,
        bounce: false
      });
      if (this.listenScroll) {
        const me = this;
        this.scroll.on('scroll', (pos) => {
          me.$emit('scroll', pos);
        });
      }
      if (this.pullup) {
        // scrollEnd表示scroll停止了，scrollToEnd表示滚动到底部了
        this.scroll.on('scrollEnd', () => {
          if (this.scroll.y <= (this.scroll.maxScrollY + 50)) {
            this.$emit('scrollToEnd');
          }
        });
      }

      if (this.beforeScroll) {
        this.scroll.on('beforeScrollStart', () => {
          this.$emit('beforeScroll');
        });
      }
    },
    disable() {
      this.scroll && this.scroll.disable();
    },
    enable() {
      this.scroll && this.scroll.enable();
    },
    refresh() {
      this.scroll && this.scroll.refresh();
    },
    scrollTo() {
      // eslint-disable-next-line
      this.scroll && this.scroll.scrollTo.apply(this.scroll, arguments);
    },
    scrollToElement() {
      // eslint-disable-next-line
      this.scroll && this.scroll.scrollToElement.apply(this.scroll, arguments);
    },
    finishPullUp() {
      this.scroll && this.scroll.finishPullUp();
    }
  },
  watch: {
    data() {
      setTimeout(() => {
        this.refresh();
      }, this.refreshDelay);
    }
  }
};
</script>

ToT这样一个组件就写好辣。。。
