本文主要分为两个部分，小程序主体部分及小游戏页面部分
一、小程序主体部分
一个小程序主体部分由三个文件组成，必须放在项目的根目录，如下：
1. 小程序逻辑
App({
onLaunch: function() {
// Do something initial when launch. },
onShow: function() { // Do something when show. },
onHide: function() { // Do something when hide. },
globalData: 'I am global data'})2. 小程序公共设置
主要注册一个页面，即2048游戏主页
{
"pages":[
"pages/index/index"
],
"window":{
"navigationBarBackgroundColor":"#ffffff",
"navigationBarTextStyle":"#1AAD16",
"navigationBarTitleText":"2048游戏",
"backgroundColor":"#eeeeee",
"backgroundTextStyle":"light" },
"networkTimeout": {
"request": 10000,
"downloadFile": 10000 },
"debug": false
}二、小游戏页面部分
2048游戏小程序页面主要由以下文件组成。
1. 页面结构
其页面结构代码如下
<view class="container">
<view class="game-body">
<loading hidden="{{hidden}}">
加载中... </loading>
<view class="heading">
<text class="title">2048</text>
<view class="scores-container">
<view class="score-container">{{score}}</view>
<view class="best-container">{{highscore}}</view>
</view>
</view>
<view class="above-game">
<text class="game-intro">你能拿到2048吗？</text>
<text class="restart-button" bindtap="restart">新游戏</text>
</view>
<view class="game-container">
<view class="game-message game-{{over ? (win ? 'won' : 'over') : ''}}">
<text class="over-msg">{{overMsg}}</text>
<view class="lower">
<!-- <text class="keep-playing-button">继续</text> -->
<text class="retry-button" bindtap="restart">再试一次</text>
</view>
</view>
<view class="grid-container" bindtouchstart="touchStart" bindtouchmove="touchMove" bindtouchend="touchEnd">
<view wx:for="{{grids}}" wx:for-index="rowIdx" wx:for-item="row" class="grid-row">
<view wx:for="{{row}}" wx:for-index="colIdx" wx:for-item="cell" class="grid-cell">
<view class="tile tile-{{cell.value}}">
<view wx:if="{{cell}}" class="tile-inner">
{{cell.value}} </view>
</view>
</view>
</view>
</view>
</view>
<!-- <view class="game-explanation">
<view class="important">如何开始：</view> 手指上下左右滑动
</view> --></view></view>2. 样式表
样式代码如下所示
