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);
}
