1、给渲染的数据加上滚动加载 和 uni-load-more 组件
- <scroll-view class="list" scroll-y="true">
-
- </scroll-view>
-
- <uni-load-more :status="status" :content-text="contentText" />
2、引入组件 和 数据初始化
- import uniLoadMore from "@/uni_modules/uni-load-more/components/uni-load-more/uni-load-more.vue"
- export default {
- components: {
- uniLoadMore
- },
- data() {
- return {
- searchValue: '',
- universityList: [],
- page: 1,
- limit: 10,
- status: 'more',
- contentText: {
- contentdown: '查看更多',
- contentrefresh: '加载中',
- contentnomore: '没有更多'
- },
- }
- },
3、加上下拉刷新和上拉加载
下拉刷新的时候将 页码重置为1
上拉加载的时候 如果没有更多则不加载数据 否则 page ++ 然后获取第二页的数据
- //下拉刷新
- onPullDownRefresh() {
- this.page = 1;
- uni.stopPullDownRefresh();
- this.universityList = [];
- this.getUniversityList()
- },
- //上拉加载
- onReachBottom() {
- if (this.status == 'noMore') {
- return;
- }
- this.page++;
- this.getUniversityList();
- },
4、接收数据 如果页码为1 则直接赋值 否则 加上之前的数据
判断数据的长度是否小于 我们需要的长度 如果小于 那就是没有更多数据
- if (this.page === 1) {
- this.universityList = res.data;
- } else {
- this.universityList = this.universityList.concat(res.data);
- }
- // 判断是否还有更多数据
- if (res.data.length < this.limit) {
- this.status = 'noMore'; // 没有更多数据
- } else {
- this.status = 'more'; // 还有更多数据
- }
