微信小程序分页和下拉刷新

news 来源：原创 2025/4/29 7:05:34

在page.json中配置下拉刷新和底部距顶部的距离：

{"path": "school-detail","style": {"navigationStyle": "custom","navigationBarTextStyle": "black","enablePullDownRefresh": true, //下拉刷新"onReachBottomDistance":100  //底部距顶部的距离}},

如下页面接口，需要分页的页面，在后端接口中都需要page_size(一次加载的数据条数）

//推免信息
export const getExemption = async (id: number,pageSize: number): Promise<exemption> => {try {const res = await http<exemption>({method: 'POST',url: '/universityselectionserver/postgraduate-exemption',data: {token: memberStore.profile?.token,user_id: memberStore.profile?.user_id,college_code: 10486,last_id: 0,page_size: 10}});return res.data;} catch (error) {console.error("Failed to fetch major score:", error);return {} as exemption;}
}

下面是在相应页面的页面刷新和分页的代码

const currentPage_exemption = ref(1);
const pageSize_exemption = ref(10);
const hasMore_exemption = ref(true);
//推免数据的分页加载和下拉刷新
const fetchExemption = async () => {if(loading.value) return;loading.value = true;try {const response = await getExemption(currentPage_exemption.value,pageSize_exemption.value);console.log('推免数据:', response);if(currentPage_exemption.value === 1) {exemptionList.value = props.infoList;}else {exemptionList.value = [...exemptionList.value,...props.infoList];}hasMore_exemption.value = props.infoList.length >= pageSize_exemption.value;}catch (error) {console.error('获取推免数据失败', error);}finally {loading.value = false;uni.stopPullDownRefresh();};
}
onMounted(() => {fetchNotice();fetchExemption();
});
onPullDownRefresh(() => {currentPage.value = 1;hasMore.value = true;currentPage_exemption.value = 1;hasMore_exemption.value = true;fetchNotice();fetchExemption();
})
onReachBottom(() => {if(hasMore.value) {currentPage.value++;fetchNotice();}if(hasMore_exemption.value) {currentPage_exemption.value++;fetchExemption();}
})
