uniapp 实战demo

1.uniapp 从列表进入详情页，再返回列表页时回到上次的浏览位置

<script>
export default {
    data() {
        return {
            listData: [],
            scrollTop: 0,//浏览位置
        };
    },
    onShow() {
        this.getShopData();
    },
    onPageScroll: function (e) {
    	// 当页面滚动时保存值
        this.scrollTop = e.scrollTop;
    },
    onBackPress(options) {
        //列表页点击页面左上角的返回按钮时从本地缓存中移除指定的key
        if (options.from === 'backbutton') {
            uni.removeStorage({
                key: 'newsTop'
            });
            uni.navigateBack();
            return true;
        }
    },
    methods: {
        getShopData() {
            getShopList()
                .then((res) => {
                    this.listData = res.data.list.data;
					// 渲染完数据后将页面滚动到目标位置
                    uni.getStorage({
                        key: 'newsTop',
                        success: (res) => {
                            console.log(res);
                            if (res.data) {
                                uni.pageScrollTo({
                                    scrollTop: res.data,
                                    duration: 0,
                                });
                            }
                        },
                    });
                })
                .finally(() => {});
        },
        editShop(storeId = '') {
        	//跳转详情页时将最后的滚动距离存到缓存中
            uni.setStorage({
                key: 'newsTop',
                data: this.scrollTop,
            });
            uni.navigateTo({
                url: '/pages/edit/shop/shop?store_id=' + storeId,
            });
        },
        
    },
};
