vue中利用iscroll.js解决pc端滚动问题

setTimeout(() => {
vnode.scroll.refresh()
}, 0)
},
unbind: function (el, binding, vnode, oldVnode) {
// 解除绑定时要把iscroll销毁
vnode.scroll = oldVnode.scroll
vnode.scroll.destroy()
vnode.scroll = null
}
})
}
}
module.exports = VIScroll

这里附上 iscroll.js 5 官方文档地址， iscroll npm 包地址，相关属性和方法自行查看。

2、加载引用指令

首先在 main.js 中加载指令：

import Vue from 'vue'
import App from './App.vue'
import "./assets/reset.css"
// 加载scroll指令
import VIscroll from './directive/vIscroll'
Vue.use(VIscroll)
Vue.config.productionTip = false
new Vue({
 render: h => h(App),
}).$mount('#app')

使用指令，摘自 tabList.vue 组件部分代码如下：

<template>
 <div class="tab-container">
 <div
  class="scroll-container"
  v-iscroll="{
  option: iscrollConf,
  instance: getIscroll
  }"
  ref="scrollContainer"
 >
  <ul
  class="tab-li-container"
  ref="tabLiContainer"
  >
  <li
   class="tab-li-item"
   v-for="(item, index) in list"
   :key="item.id"
   :id="item.id"
   ref="tabItem"
   @click="tabEvent(item, index)"
  >
   <div
   class="item"
   :class="{
    'item-active': currentId == item.id
   }"
   >{{item.num}}</div>
  </li>
  </ul>
 </div>
 <div
  class="tab-left"
  @click="tabBtnEvent('left')"
 ><</div>
 <div
  class="tab-right"
  @click="tabBtnEvent('right')"
 >></div>
 </div>
</template>
<script>
export default {
 props: ['list'],
 data () {
 return {
  iscrollConf: {
  bounce: true,
  mouseWheel: true,
  click: true,
  scrollX: true,
  scrollY: false
  },
  currentId: null,
  currentIndex: 0,
  myScroll: null
 }
 },
 mounted () {
 this.$refs.tabLiContainer.style.width = this.$refs.tabItem[0].offsetWidth * this.list.length + 'px'
 this.$nextTick(() => {
  this.myScroll.refresh()
 })
 },
 methods: {
 tabEvent (item, currentIndex) {
  <!--点击某个li 按钮事件处理逻辑-->
 },
 tabBtnEvent (direction) {
  <!--左右切换逻辑事件-->
 },
 getIscroll (iscroll) {
  this.myScroll = iscroll
 }
 },
 watch: {
 list: {
  handler (l) {
  this.currentId = l[0].id
  },
  immediate: true,
  deep: true
 }
 }
}
</script>
<style scoped>
// 样式
</style>

上述代码中 v-iscroll 指令传入两个字段参数：
