vue如何实现的上拉加载更多数据/分页功能示例

本文实例讲述了vue实现的上拉加载更多数据/分页功能。分享给大家供大家参考，具体如下：

加载状态

<div v-if='has_log == 0'>
   <load-more tip="上拉加载" :show-loading="false" background-color="#fbf9fe"></load-more>
  </div>
  <div v-if='has_log == 1'>
   <load-more tip="正在加载" :show-loading="true"></load-more>
  </div>
  <div v-if='has_log == 2'>
    <load-more tip="没有更多数据了" :show-loading="false" background-color="#fbf9fe"></load-more>
  </div>

js

export default {
 name: '',
 data () {
  return {
   list: [],
   now_item: '',
   current_index: 0,
   list_param: {page: 1},
   no_data: false,
   has_log: 0
  }
 },
 components: {
  XInput
 },
 created () {
  this.get('/api/index/index', this.list_param).then((data) => {
   this.list = data.data.data
   this.list_param.page += 1
  })
  window.addEventListener('scroll', this.onScroll)
 },
 methods: {
  onScroll () {
   this.has_log = 1
   let innerHeight = document.querySelector('#app').clientHeight
   let outerHeight = document.documentElement.clientHeight
   let scrollTop = document.documentElement.scrollTop
   // console.log(innerHeight + ' ' + outerHeight + ' ' + scrollTop)
   // console.log(outerHeight + scrollTop - 30)
   // console.log(innerHeight)
   if (outerHeight + scrollTop === innerHeight + 57) {
    if (this.no_data === true) {
     this.has_log = 2
     return false
    }
    this.get('/api/index/index', this.list_param).then((data) => {
     if (data.data.data.length > 0) {
      this.list = [...this.list, ...data.data.data]
      this.list_param.page = this.list_param.page + 1
      this.has_log = 0
     } else {
      this.has_log = 2
      this.no_data = true
     }
    })
   }
  }
 }
}

希望本文所述对大家vue.js程序设计有所帮助。
