uni-app之實現分頁

挑戰者V發表於2020-06-19

一、下載庫

官方文件地址為:
https://ext.dcloud.net.cn/plugin?id=32

點選下載zip壓縮包即可，下載完畢後解壓到放置前端相關元件目錄,即components目錄。

二、使用

1.引入

import uniPagination from '../../components/uni-pagination/uni-pagination/uni-pagination.vue'

2.模板區域使用(在裡)

<uni-pagination @change="handlePage" show-icon="true" :total="postCount" :current="pageNum" :pageSize="pageSize"></uni-pagination>

3.編寫handlePage函式

handlePage(params){
            var pageIndex = params.current;
        
            console.log("this.pageNum:"+pageIndex);
        
            this.getPostListInfo(pageIndex)
        }

4.我的完整程式碼如下

<template>
	<view class="content">
		<!-- 	<image class="logo" src="/static/logo.png"></image> -->
		<view class="text-area">
			<text class="title">{{ title }}</text>
		</view>
		<view class="uni-list">
			<view class="uni-list-cell" hover-class="uni-list-cell-hover" v-for="(item, index) in list" :key="index">
				<!-- 	<view class="uni-list-cell-navigate uni-navigate-right">{{ item.Title }}</view> -->

				<button type="default" @click="getDetail(item.Title, item.Id, item.Url)">{{ item.Title }}</button>
			</view>
			<uni-pagination @change="handlePage" show-icon="true" :total="postCount" :current="pageNum" :pageSize="pageSize"></uni-pagination>
		</view>
	</view>
</template>

<script>
import common from '../../common/common.js';
import uniPagination from '../../components/uni-pagination/uni-pagination/uni-pagination.vue';
export default {
	components: { uniPagination },
	data() {
		return {
			title: '文章列表',
			postCount: 0,
			pageSize: 10,
			pageNum: 1,
			list: []
		};
	},

	onLoad() {
		this.getPostListInfo(this.pageNum);

		this.getPersonalBlogInfo();
	},
	methods: {
		getPostListInfo(pageIndex) {
			console.log('pageIndex:' + pageIndex);
			uni.request({
				url: common.website_url + '/cnblogs/getPersonalBlogPostList/' + pageIndex,
				method: 'POST',
				success: res => {
					console.log('isSuccess');
					console.log('getPostListInfo:' + JSON.stringify(res.data));
					this.list = res.data;
				},
				fail: function(e) {
					console.log('介面呼叫失敗:' + JSON.stringify(e));
				}
			});
		},

		getPersonalBlogInfo() {
			uni.request({
				url: common.website_url + '/cnblogs/getPersonalBlogInfo',
				method: 'POST',
				success: res => {
					//console.log('getPersonalBlogInfo:' + JSON.stringify(res.data));
					this.postCount = res.data.postCount;
					this.pageSize = res.data.pageSize;
				},
				fail: function(e) {
					console.log('介面呼叫失敗:' + JSON.stringify(e));
				}
			});
		},
		getDetail(Title, Id, Url) {
			console.log('Title:' + Title + '  Id:' + Id);

			uni.navigateTo({
				url: '../post/post/post?Title=' + Title + '&Id=' + Id
			});
		},
		handlePage(params) {
			var pageIndex = params.current;

			console.log('this.pageNum:' + pageIndex);

			this.getPostListInfo(pageIndex);
		}
	}
};
