這篇文章主要為大家詳細(xì)介紹了vue實(shí)現(xiàn)頁面滾動到底部刷新，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了vue實(shí)現(xiàn)頁面滾動到底部刷新的具體代碼，供大家參考，具體內(nèi)容如下

h5頁面

 <script>
    var app = new Vue({
      el: '#app',
      data: {
        swiper: null,
        carousel: [],
        promotion: [],
        cates: [],
        //設(shè)置size初始為10
        size:10,
      },
      mounted: function () {
        //定義that用that.size獲取size的值
        var that=this;
        getPromotion();
        //秒表每秒請求一次
        setInterval(function(){
          //content是div類名
          const el = document.querySelector('.content');
          const offsetHeight = el.offsetHeight;
          el.onscroll = () => {
            const scrollTop = el.scrollTop;
            const scrollHeight = el.scrollHeight;
            if ((offsetHeight + scrollTop) - scrollHeight >= -1) {
              //每次滾動到底部size+10
              that.size+=10;
            }
          }
          $.ajax({
            type: "post",
            url: "/news/search",
            data: {intro: 'best', page: 1, size: that.size},
            dataType: 'json',
            success: function (data) {
              $.hideIndicator();
              if (data.errCode === 1) {
                app.promotion = data.data.articleList;
                // console.log(222);
              } else {
                $.toast(data.errMsg);
              }
            }
          });
        },10*60);
        // window.addEventListener('scroll', this.scrollBottom());
      },
      methods: {
        goDetail: function (id) {
          location.href = '/news/newsDetail/' + id;
        },
 
 
      },
 
    });
    //第一次加載先獲取10條
    function getPromotion() {
      $.ajax({
        type: "post",
        url: "/news/search",
        data: {intro: 'best', page: 1, size: 10},
        dataType: 'json',
        success: function (data) {
          $.hideIndicator();
          if (data.errCode === 1) {
            app.promotion = data.data.articleList;
            // console.log(data);
          } else {
            $.toast(data.errMsg);
          }
        }
      });
      $.showIndicator();
    }


</script>

后臺控制器

public function search()
  {
    $parm = array('act' => 'search');
    if (!empty($_POST['catId'])) $parm['catId'] = $_POST['catId'];
    if (!empty($_POST['keyword'])) $parm['keyword'] = $_POST['keyword'];
    if (!empty($_POST['intro'])) $parm['intro'] = $_POST['intro'];
    if (!empty($_POST['order'])) $parm['order'] = $_POST['order'];
    if (!empty($_POST['sort'])) $parm['sort'] = $_POST['sort'];
    if (!empty($_POST['page'])) $parm['page'] =1;
    //獲取前臺傳過來的size值如果不為空就設(shè)置請求接口時(shí)多一個(gè)size參數(shù)
    if (!empty($_POST['size'])) $parm['size'] = $_POST['size'];
    //調(diào)用接口
    $data = $this->http('service/article.php', $parm);
    echo json_encode($data);
  }
