基於vue2.0以及better-scroll實現scroll滑動元件及所實現元件的應用例子

直接上原始碼:

元件:scroll.vue,需要先npm install better-scroll

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

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

  const DIRECTION_H = 'horizontal'
  const DIRECTION_V = 'vertical'

  export default {
    props: {
      probeType: {
        type: Number,
        default: 1
      },
      click: {
        type: Boolean,
        default: false
      },
      listenScroll: {
        type: Boolean,
        default: false
      },
      data: {
        type: Array,
        default: null
      },
      pullup: {
        type: Boolean,
        default: false
      },
      beforeScroll: {
        type: Boolean,
        default: false
      },
      refreshDelay: {
        type: Number,
        default: 20
      },
      direction: {
        type: String,
        default: DIRECTION_V
      }
    },
    mounted() {
      setTimeout(() => {
        this._initScroll()
      }, 20)
    },
    methods: {
      _initScroll() {
        if (!this.$refs.wrapper) {
          return
        }
        this.scroll = new BScroll(this.$refs.wrapper, {
          probeType: this.probeType,
          click: this.click,
          eventPassthrough: this.direction === DIRECTION_V ? DIRECTION_H : DIRECTION_V
        })

        if (this.listenScroll) {
          this.scroll.on('scroll', (pos) => {
            this.$emit('scroll', pos)
          })
        }
        if (this.pullup) {
          this.scroll.on('scrollEnd', () => {
            if (this.scroll.y <= (this.scroll.maxScrollY + 50)) {
              this.$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() {
        this.scroll && this.scroll.scrollTo.apply(this.scroll, arguments)
      },
      scrollToElement() {
        this.scroll && this.scroll.scrollToElement.apply(this.scroll, arguments)
      }
    },
    watch: {
      data() {
        setTimeout(() => {
          this.refresh()
        }, this.refreshDelay)
      }
    }
  }
</script>

<style scoped lang="stylus" rel="stylesheet/stylus">

</style>

應用方法:

引入並註冊元件:

  import Scroll from 'base/scroll/scroll'
  export default {
    components: {
      Scroll
    }
  }

template結構以及style:


效果:圖中輪播圖+列表為滾動區域(recommend-content),即需要滾動的內容;對應的class:slider為輪播圖,recommend-list為列表。由於輪播圖資料以及list資料為動態獲取,實際使用請填充你的資料,以上只給出關鍵結構。


已實現滾動:
