這篇文章主要介紹微信小程序搜索分頁功能怎么實現,文中介紹的非常詳細,具有一定的參考價值,感興趣的小伙伴們一定要看完!
這里以搜索歌曲為例:
前端:
<view class="search"> <view class="search-bar"> <view class="search-wrap"> <icon type="search" size="16" class="icon-search" /> <input type="text" placeholder="請輸入搜索內容" class="search-input" name="searchKeyword" bindinput="bindKeywordInput" value="{{searchKeyword}}" /> </view> <view class="search-cancel" bindtap="keywordSearch">搜索</view> </view> <view class="search-result"> <scroll-view scroll-y="true" bindscrolltolower="searchScrollLower"> <view class="result-item" wx:for="{{searchSongList}}" wx:key="unique" data-data="{{item}}" > <view class="icon{{item.isonly=='0' ? ' nocopyright' : ''}}"></view> <text class="title">{{item.SongName}}--{{item.SingerName}}</text> <view class="subtitle"> <text>{{item.SingerName}}</text> </view> </view> <view class="loading" hidden="{{!searchLoading}}">正在載入更多...</view> <view class="loading complete" hidden="{{!searchLoadingComplete}}">已加載全部</view> </scroll-view> </view> </view>
樣式:
page{ display: flex; flex-direction: column; height: 100%; } /*搜索*/ .search{ flex: auto; display: flex; flex-direction: column; background: #fff; } .search-bar{ flex: none; display: flex; align-items: center; justify-content: space-between; padding: 20rpx; background: #f4f4f4; } .search-wrap{ position: relative; flex: auto; display: flex; align-items: center; height: 80rpx; padding: 0 20rpx; background: #fff; border-radius: 6rpx; } .search-wrap .icon-search{ margin-right: 10rpx; } .search-wrap .search-input{ flex: auto; font-size: 28rpx; } .search-cancel{ padding: 0 20rpx; font-size: 28rpx; } /*搜索結果*/ .search-result{ flex: auto; position: relative; } .search-result scroll-view{ position: absolute; bottom: 0; left: 0; right: 0; top: 0; } .result-item{ position: relative; display: flex; flex-direction: column; padding: 20rpx 0 20rpx 110rpx; overflow: hidden; border-bottom: 2rpx solid #e5e5e5; } .result-item .media{ position: absolute; left: 16rpx; top: 16rpx; width: 80rpx; height: 80rpx; border-radius: 999rpx; } .result-item .title, .result-item .subtitle{ overflow: hidden; text-overflow: ellipsis; white-space: nowrap; line-height: 36rpx; } .result-item .title{ margin-bottom: 4rpx; color: #000; } .result-item .subtitle{ color: #808080; font-size: 24rpx; } .result-item:first-child .subtitle text{ margin-right: 20rpx; } .result-item:not(:first-child) .subtitle text:not(:first-child):before{ content: '/'; margin: 0 8rpx; } .loading{ padding: 10rpx; text-align: center; } .loading:before{ display: inline-block; margin-right: 5rpx; vertical-align: middle; content: ''; width: 40rpx; height: 40rpx; /* background: url(../../images/icon-loading.png) no-repeat; */ background-size: contain; animation: rotate 1s linear infinite; } .loading.complete:before{ display: none; }
js:
var util = require('../../utils/util.js') Page({ data: { searchKeyword: '', //需要搜索的字符 searchSongList: [], //放置返回數據的數組 isFromSearch: true, // 用于判斷searchSongList數組是不是空數組,默認true,空的數組 searchPageNum: 1, // 設置加載的第幾次,默認是第一次 callbackcount: 15, //返回數據的個數 searchLoading: false, //"上拉加載"的變量,默認false,隱藏 searchLoadingComplete: false //“沒有數據”的變量,默認false,隱藏 }, //輸入框事件,每輸入一個字符,就會觸發一次 bindKeywordInput: function (e) { console.log("輸入框事件") this.setData({ searchKeyword: e.detail.value }) }, //搜索,訪問網絡 fetchSearchList: function () { let that = this; let searchKeyword = that.data.searchKeyword,//輸入框字符串作為參數 searchPageNum = that.data.searchPageNum,//把第幾次加載次數作為參數 callbackcount = that.data.callbackcount; //返回數據的個數 //訪問網絡 util.getSearchMusic(searchKeyword, searchPageNum, callbackcount, function (data) { console.log(data) //判斷是否有數據,有則取數據 if (data.status != 0) { let searchList = []; //如果isFromSearch是true從data中取出數據,否則先從原來的數據繼續添加 that.data.isFromSearch ? searchList = data.data.lists : searchList = that.data.searchSongList.concat(data.data.lists) that.setData({ searchSongList: searchList, //獲取數據數組 //存放歌手屬性的對象 // searchLoading: true //把"上拉加載"的變量設為false,顯示 }); //沒有數據了,把“沒有數據”顯示,把“上拉加載”隱藏 } else { that.setData({ searchLoadingComplete: true, //把“沒有數據”設為true,顯示 searchLoading: false //把"上拉加載"的變量設為false,隱藏 }); } }) }, //點擊搜索按鈕,觸發事件 keywordSearch: function (e) { this.setData({ searchPageNum: 1, //第一次加載,設置1 searchSongList: [], //放置返回數據的數組,設為空 isFromSearch: true, //第一次加載,設置true searchLoading: true, //把"上拉加載"的變量設為true,顯示 searchLoadingComplete: false //把“沒有數據”設為false,隱藏 }) this.fetchSearchList(); }, //滾動到底部觸發事件 searchScrollLower: function () { let that = this; if (that.data.searchLoading && !that.data.searchLoadingComplete) { that.setData({ searchPageNum: that.data.searchPageNum + 1, //每次觸發上拉事件,把searchPageNum+1 isFromSearch: false //觸發到上拉事件,把isFromSearch設為為false }); that.fetchSearchList(); } } })
function getSearchMusic(keyword, pageindex, callbackcount, callback) { wx.request({ url: 'http://songsearch.kugou.com/song_search_v2', data: { keywords:'莊心妍', clientver:'=& platform=WebFilter' }, // method: 'post', header: { 'content-Type': 'application/json' }, success: function (res) { // console.log(res) if (res.statusCode == 200) { callback(res.data); } } } }
