uniapp 上拉刷新加载更多数据_uniapp onshow 加载赋值

1. 用到uniapp的组件

<uni-load-more :status="status" :content-text="contentText"></uni-load-more>

2. 定义变量

data() {
    return {
		dataList: [],
		last_id: '',
		reload: true, //判断是否为第一轮加载，以便赋予index值
		time: 1, //该值是为了动态更新向服务器传递的参数值
		index: 0, //为获取的数据进行分段处理，十条数据一加载
		loadingFlag: true, //判断是否继续上拉加载数据
		status: 'more', //加载状态
		contentText: {
		    contentdown: '点击记载更多',
			contentrefresh: '正在加载...',
			contentnomore: '没有更多数据了'
		}
	};
},

3.  增加事件

onShow() {
		this.getDynamicList();
},
// 触底加载更多
onReachBottom() {
	if (this.loadingFlag == true) {
		this.status = 'more';
		this.getDynamicList();
	}
},

4. 调用接口获取数据，每次获取五条数据，没下拉加载一次获取五条数据

getDynamicList() {
	let that = this;
	let params = {
		offset: 0,
		pageSize: 5
	};
	if (that.last_id) {
		that.status = 'loading';
		params.offset = that.time * 5;
		that.time++;
	}
	console.log('params:', params);
	newsList(params).then(res => {
		if (res.statusCode == 200) {
			let data = res.data.rows;
			let list = [];
			let num = params.pageSize - data.length;
			if (that.reload && data.length == 0) {
				return false;
			} else {
			    if (!that.reload) {
				    that.index += 5;
				}
				if (num !== 0) {
					that.status = 'noMore';
					that.loadingFlag = false;
				}
				for (let j = 0; j < data.length; j++) {
					list.push(data[j]);
				}
				that.last_id = list[list.length - 1].id;
				that.dataList = that.reload ? list : that.dataList.concat(list);
				that.reload = false;
			}
		}
	});
},

亲测有效
