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;
}
