微信小程式基本組件和API已擼完,總歸要回到正題的,花了大半天時間做了個精簡版的百思不得姐,包括段子,圖片,音頻,視頻,四個模組。這篇就帶著大家簡述下這個小小的APP,原始碼會放到GitHub上歡迎start。
計畫中我能學到什麼?
tabbar使用方式
網路呼叫真實介面
loading使用
scroll-view實現下拉刷新上拉加載
image組件對圖片的處理,
音樂和視頻組件的使用
image組件對圖片的處理,音樂和視頻組件的使用image組件對圖片的處理,
音樂和視頻組件的使用
image組件對圖片的處理,音樂和視頻組件的使用
等等等。 。 。 。 app.json全域設定檔{ "pages":[ "pages/word/word", "pages/image/image", "pages/voice/voice", "pages/video/video", "pages/detail/detail" ], "tabBar": { "color": "#a9b7b7", "selectedColor": "#eb4f38", "borderStyle": "white", "backgroundColor": "#ffffff", "list": [ { "pagePath": "pages/word/word", "text": "段子", "iconPath": "image/wordN.png", "selectedIconPath": "image/wordS.png" }, { "pagePath": "pages/image/image", "text": "图片", "iconPath": "image/imageN.png", "selectedIconPath": "image/imageS.png" }, { "pagePath": "pages/voice/voice", "text": "声音", "iconPath": "image/voiceN.png", "selectedIconPath": "image/voiceS.png" }, { "pagePath": "pages/video/video", "text": "视频", "iconPath": "image/videoN.png", "selectedIconPath": "image/videoS.png" } ] }, "window":{ "backgroundTextStyle":"light", "navigationBarBackgroundColor": "#eb4f38", "navigationBarTextStyle":"white" } }
/*整体view样式*/ .containsView{ padding: 15rpx 15rpx 15rpx 15rpx; margin-top: 15rpx; margin-bottom: 15rpx; background-color: white; } /*头部整体样式*/ .topContainsView{ display: flex; flex-direction: row; align-items: center; margin-bottom: 18rpx; } /** * 头像样式 */ .profileImage{ width: 60rpx; height: 60rpx; border-radius: 30rpx; } /*头部显示名字和时间整体样式*/ .topRightView{ margin-left: 15rpx; display: flex; flex-direction: column; } /*用户名称样式*/ .topRightName{ font-size: 18rpx; } /*时间样式*/ .topRightTime{ font-size: 14rpx; color: #b8b2b2; margin-top: 10rpx; } /*因为中间部分不一样不放在整体样式中*/ /*底部view整体样式*/ .bottomView{ display: flex; flex-direction: row; justify-content: space-between; align-items: center; } /*每个Item样式*/ .bottomItemView{ display: flex; flex-direction: row; align-items: center; justify-content: center; margin-top: 18rpx; padding-left: 10rpx; padding-right: 10rpx; } /*Item样式中的图标样式 顶 踩 分享 评论*/ .bottomItemImage{ width: 45rpx; height: 45rpx; } /*Item中的文字样式 顶 踩 分享 评论*/ .bottomItemText{ font-size: 15rpx; color: #b8b2b2; margin-left: 10rpx; margin-top: 8rpx; } /*分割线样式*/ .divLine{ background: #f3f3f3; width: 100%; height: 15rpx; }
app.wxss我將四個模組分為三個部分頭部,內容區域, 底部因為每個頁面頭部,底部樣式都一樣而中間部分不一樣所以我把1,3抽到全局中,註解比較清晰
段子模組
word.wxml<loading hidden="{{loadingHidden}}">正在加载...</loading> <scroll-view scroll-y="true" bindscrolltoupper="bindscrolltoupper" bindscrolltolower="bindscrolltolower" style="height: 100%"> <block wx:for-items="{{list}}"> <!-- 分割线 --> <view class="divLine"></view> <!-- 整体item样式 --> <view class="containsView"> <view class="topContainsView"> <image class="profileImage" src="{{item.profile_image}}" /> <view class="topRightView"> <text class="topRightName">{{item.name}}</text> <text class="topRightTime">{{item.passtime}}</text> </view> </view> <!-- 中间内容 --> <text class="centerContent">{{item.text}}</text> <!-- 底部view样式 --> <view class="bottomView"> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/ding.png" /> <text class="bottomItemText">{{item.ding}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/cai.png" /> <text class="bottomItemText">{{item.cai}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/share.png" /> <text class="bottomItemText">{{item.repost}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/comment.png" /> <text class="bottomItemText">{{item.comment}}</text> </view> </view> </view> </block> </scroll-view>
Page({ data: { list: [], maxtime: '', loadingHidden: false }, onLoad: function (options) { // 页面初始化 options为页面跳转所带来的参数 //加载最新 this.requestData('newlist'); }, /** * 上拉刷新 */ bindscrolltoupper: function () { //加载最新 // this.requestData('newlist'); }, /** * 加载更多 */ bindscrolltolower: function () { console.log('到底部') //加载更多 this.requestData('list'); }, /** * 请求数据 */ requestData: function (a) { var that = this; console.log(that.data.maxtime) wx.request({ url: 'http://api.budejie.com/api/api_open.php', data: { a: a, c: 'data', maxtime: that.data.maxtime, type: '29', }, method: 'GET', success: function (res) { console.log(res) console.log('上一页', that.data.list) that.setData({ // 拼接数组 list: that.data.list.concat(res.data.list), loadingHidden: true, maxtime: res.data.info.maxtime }) } }) }, onReady: function () { // 页面渲染完成 }, onShow: function () { // 页面显示 }, onHide: function () { // 页面隐藏 }, onUnload: function () { // 页面关闭 } })
圖片模組
image.wxml
<loading hidden="{{loadingHidden}}">正在加载...</loading> <scroll-view scroll-y="true" bindscrolltolower="bindscrolltolower" style="height: 100%"> <block wx:for-items="{{list}}"> <!-- 分割线 --> <view class="divLine"></view> <!-- 整体item样式 --> <view class="containsView"> <view class="topContainsView"> <image class="profileImage" src="{{item.profile_image}}" /> <view class="topRightView"> <text class="topRightName">{{item.name}}</text> <text class="topRightTime">{{item.passtime}}</text> </view> </view> <text style="font-size: 30rpx">{{item.text}}</text> <!-- 当时gif图 --> <view wx:if="{{item.is_gif != 0}}" style="position: relative;"> <image class="centerContent" src="{{item.cdn_img}}" mode="aspectFill" /> </view> <!-- 普通大图 可点击查看全部图片 --> <view data-url="{{item.cdn_img}}" data-height="{{item.height}}" data-width="{{item.width}}" bindtap="lookBigPicture" wx:elif="{{item.is_gif == 0}}" style="position: relative;"> <!-- 图片资源 --> <image class="centerContent" src="{{item.cdn_img}}" mode="aspectFill" /> <!-- 图片上浮动的点击查看详情图片view --> <view class="flexView"> <image src="../../image/seeBigPicture.png" style="width: 60rpx; height: 60rpx;" /> <text class="flexText">点击查看全图</text> </view> </view> <!-- 底部view样式 --> <view class="bottomView"> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/ding.png" /> <text class="bottomItemText">{{item.ding}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/cai.png" /> <text class="bottomItemText">{{item.cai}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/share.png" /> <text class="bottomItemText">{{item.repost}}</text> </view> <view class="bottomItemView"> <image class="bottomItemImage" src="../../image/comment.png" /> <text class="bottomItemText">{{item.comment}}</text> </view> </view> </view> </block> </scroll-view>
這裡主要看中間部分我們透過gif符號,結合介面和image.wxss看
image.wxss
/*中间文字样式*/ .centerContent{ margin-top: 20rpx; width: 100%; height: 600rpx; } /*中间浮动文字样式*/ .flexView{ display: flex; justify-content: center; align-items: center; width: 100%; height: 80rpx; position: absolute; z-index: 2; top: 540rpx; background: #000000; opacity: 0.6 } /*浮动文字*/ .flexText{ color: white; font-size: 35rpx; }
image.js
