开发工具:微信开发者工具 0.14.140900

功能:

  • 活动列表

预览

在开发主页的过程中,想要给小程序加个启动页,试着从豆瓣同城的角度想一句Slogan。于是,便有了这张朦胧的雨中街区图片,右上显示Slogan:“在这陌生的城市里,能与你相遇,真好”。

.slogan-wrapper {display: flex;position: fixed;height: 60%;top: 140rpx;width: 100%;padding: 0rpx 30rpx 0rpx 30rpx;flex-direction: row-reverse;box-sizing: border-box;
}.slogan-text {color: #fff;writing-mode: vertical-lr;display: inline-block;font-size: 56rpx;font-weight: 500;margin-left: 12rpx;margin-right: 12rpx;
}

主页从微信用户信息获取用户所在的城市,如果用户所在城市支持同城活动,则分类显示该城市的活动列表,没有则显示深圳的活动列表。

// 获取用户所在的城市uid
if (typeof app.globalData.userInfo.city == "string") {var cityUid = app.globalData.userInfo.city.toLowerCase();app.globalData.cityUid = cityUid;
}/** 处理城市信息 */
processLocationListData(data) {var locs = {};for (let idx in data) {var loc = data[idx];locs[loc.uid] = loc;}// 默认加载当前城市的活动,如果不支持当前城市,则默认加载深圳的活动var cityUid = app.globalData.cityUid;var currentLoc = null;if (!locs[cityUid]) {currentLoc = locs[defaultUid];} else {currentLoc = locs[cityUid];}app.globalData.locId = currentLoc.id;app.globalData.city = currentLoc.name;app.globalData.locs = locs;// 获取当前城市名称,如果当前城市不再列表中,则显示深圳this.setData({ "city": app.globalData.city, "currentLoc": currentLoc });// 获取当前城市的活动列表this.getEventByLocationId(currentLoc.id);
},

城市切换页,用户点击城市后返回主页并且加载该城市的活动列表。城市列表按照首字母分类排序,支持拼音跟中文搜索。

逻辑代码

data: {hotCityUid: ["beijing", "shanghai", "guangzhou", "shenzhen", "chengdu", "nanjing", "wuhan", "hangzhou", "chongqing"],hotCity: [],letterList: [],cityList: {}
},/** 处理城市信息 */
processCityListData: function (locs) {if (locs && typeof locs == "object") {// 提取热门城市var hotCity = this.data.hotCityUid.map(function (item, index, input) {return locs[item];});// 按字母顺序排序var keys = Object.keys(locs);keys.sort();// 提取所有城市并按首字母归类var cityList = {};var letterList = [];for (let idx in keys) {var key = keys[idx];var letter = key.substring(0, 1);var city = locs[key];if (!cityList[letter]) {cityList[letter] = [];letterList.push(letter);}cityList[letter].push(city);}console.log("cityList: " + cityList);this.setData({"hotCity": hotCity, "letterList": letterList, "cityList": cityList});}
},

页面布局代码

<text class="hot-city-title">热门城市</text>
<view class="hot-city"><view class="hot-city-content"><block wx:for="{{hotCity}}" wx:for-item="city"><text class="city-box" data-id="{{city.id}}" data-name="{{city.name}}" data-uid="{{city.uid}}" bindtap="bindCityTap">{{city.name}}</text></block></view>
</view>
<view class="city-list"><block wx:for="{{letterList}}" wx:for-item="letter"><text class="list-title">{{letter}}</text><view class="list-content"><block wx:for="{{cityList[letter]}}" wx:for-item="city"><text class="city-block" data-id="{{city.id}}" data-name="{{city.name}}" data-uid="{{city.uid}}" bindtap="bindCityTap">{{city.name}}</text></block></view></block>
</view>

分类筛选页,顶部的切换模块花了比较多时间,切换时页面的层级结构,显示隐藏都需要考虑。

逻辑代码

onLoad: function (options) {// 页面初始化 options为页面跳转所带来的参数var locId = options.locId;var eventType = options.type;// 初始化活动类型列表var typeCategory = {"all": { "id": "all", "name": "all", "title": "全部" },"music": { "id": "music", "name": "music", "title": "音乐" },"film": { "id": "film", "name": "film", "title": "电影" },"drama": { "id": "drama", "name": "drama", "title": "戏剧 " },"commonweal": { "id": "commonweal", "name": "commonweal", "title": "公益" },"salon": { "id": "salon", "name": "salon", "title": "讲座 " },"exhibition": { "id": "exhibition", "name": "exhibition", "title": "展览" },"party": { "id": "party", "name": "party", "title": "聚会" },"sports": { "id": "sports", "name": "sports", "title": "运动" },"travel": { "id": "travel", "name": "travel", "title": "旅行" },"course": { "id": "course", "name": "course", "title": "课程" }};// 初始化活动日期类型列表var dateCategory = {"future": { "id": "future", "name": "future", "title": "全部" },"today": { "id": "today", "name": "today", "title": "今天" },"tomorrow": { "id": "tomorrow", "name": "tomorrow", "title": "明天" },"weekend": { "id": "weekend", "name": "weekend", "title": "周末" },"week": { "id": "week", "name": "week", "title": "近期" },};// 全局保存的活动类型信息var g_eventCategory = app.globalData.eventCategory;this.setData({ "locId": locId, "type": eventType, "eventCategory": typeCategory, "current": this.data.type, "typeCategory": typeCategory, "dateCategory": dateCategory, "g_eventCategory": g_eventCategory });// 请求活动列表this.getEventListData();
},/** 选择类型 */
handleType: function (event) {this.setData({ "eventCategory": this.data.typeCategory, "current": this.data.type, "showCategory": true });this.resetMenuTap();this.setData({ "isTypeTap": true });console.log("handleType");
},/** 点击某个子类型 */
handleCategory: function (event) {var id = event.currentTarget.dataset.id;var readyData = { "showCategory": false };this.data.isTypeTap && (readyData["type"] = id);this.data.isDateTap && (readyData["date"] = id);this.setData(readyData);this.getEventListData();this.resetMenuTap();
},

页面布局代码

  <view class="session-header"><text class="type-tab {{type == 'all'?'tab-normal':'tab-HL'}}" bindtap="handleType">{{type == 'all'?'类型':g_eventCategory[type].title }}</text><text class="time-tab {{date == 'future'?'tab-normal':'tab-HL'}}" bindtap="handleTime">{{date == 'future' ? '时间' : dateCategory[date].title}}</text><text class="loc-tab" bindtap="handleLoc">地点</text></view><view wx:if="{{showCategory}}" class="category-session"><view class="type-category-session"><block wx:for="{{eventCategory}}" wx:for-item="category"><text class="category {{current == category.id ? 'category-HL': ''}}" catchtap="handleCategory" data-id="{{category.id}}" data-name="{{category.name}}" data-title="{{category.title}}">{{category.title}}</text></block></view><view class="category-cover" bindtap="handleCoverTap"></view></view>

活动详情页显示的内容比较多,图片下载,查看位置,拨打电话的功能微信小程序原生支持,很快就做出来了。这里要说的是发表评论的左右切换动画效果,活动评论依然不支持上传到服务器。由于微信小程序不支持WebView,活动内容是服务器编译好的静态页面,所以活动详情会出现网页标签。

左右切换动画逻辑

/** 用户点击感兴趣,执行动画 */
handleWish: function (event) {this.setData({ "action": "wish", "beforeAnimation": "left", "value": "" });var animation = wx.createAnimation({duration: 400,timingFunction: 'linear'})animation.translateX(375).step()this.setData({animationData: animation.export()})setTimeout(function () {this.reset();}.bind(this), 400);
},
/** 用户点击要参加,执行动画 */
handleJoin: function (event) {this.setData({ "action": "join", "beforeAnimation": "right", "value": "" });var animation = wx.createAnimation({duration: 400,timingFunction: 'linear'})animation.translateX(-375).step()this.setData({animationData: animation.export()});setTimeout(function () {this.reset();}.bind(this), 400);
},
/** 动画完成后,恢复状态 */
reset: function () {var animation = wx.createAnimation({duration: 0,timingFunction: 'linear'})animation.translateX(0).step();this.setData({ "beforeAnimation": "", animationData: animation.export() });
},

页面布局

<view class="container"><view class="session-header {{action}}-session"><text class="wish" bindtap="handleWish">感兴趣</text><text class="join" bindtap="handleJoin">要参加</text></view><view class="session-content {{beforeAnimation}}" animation="{{animationData}}"><text class="title">{{title}}</text><text class="some-count">{{somecount}}</text><textarea class="textarea" placeholder-class="placeholder" placeholder="写点评论吧..." focus="true" data-action="{{action}}" bindinput="handleInput" value="{{value}}" /><button class="confirm" size="default" type="primary" bindtap="handleComfirm" data-action="{{action}}">确定</button></view>
</view>

用户点击不同的Tab,切换不同的样式

.wish-session .wish {color: #4a4a4a;font-size: 32rpx;font-weight: 600;position: relative;border-bottom: 2px solid #4a4a4a;padding-bottom: 10rpx;left: 50%;margin-left: -50rpx;
}.wish-session .join {font-size: 24rpx;color: #9e9e9e;position: relative;left: 50%;margin-left: 40rpx;
}.join-session .wish {font-size: 24rpx;color: #9e9e9e;position: relative;left: 50%;margin-left: -140rpx;
}.join-session .join {color: #4a4a4a;font-size: 32rpx;font-weight: 600;position: relative;border-bottom: 2px solid #4a4a4a;padding-bottom: 10rpx;left: 50%;margin-left: 20rpx;
}
