vue实现页面滚动到底部刷新

本文实例为大家分享了vue实现页面滚动到底部刷新的具体代码，供大家参考，具体内容如下

h5页面 

 <script>
    var app = new Vue({
      el: '#app',
      data: {
        swiper: null,
        carousel: [],
        promotion: [],
        cates: [],
        //设置size初始为10
        size:10,
      },
      mounted: function () {
        //定义that用that.size获取size的值
        var that=this;
        getPromotion();
        //秒表每秒请求一次
        setInterval(function(){
          //content是div类名
          const el = document.querySelector('.content');
          const offsetHeight = el.offsetHeight;
          el.onscroll = () => {
            const scrollTop = el.scrollTop;
            const scrollHeight = el.scrollHeight;
            if ((offsetHeight + scrollTop) - scrollHeight >= -1) {
              //每次滚动到底部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;
        },
 
 
      },
 
    });
    //第一次加载先获取10条
    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>

后台控制器

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'])) $parm['page'] =1;
    //获取前台传过来的size值如果不为空就设置请求接口时多一个size参数
    if (!empty($_POST['size'])) $parm['size'] = $_POST['size'];
    //调用接口
    $data = $this->http('service/article.php', $parm);
    echo json_encode($data);
  }
