一、项目截图
二、源代码
1.WXML
代码如下(示例):
<view class='container'> <view class='content-bottom' bindtouchmove='touchMove' bindtouchstart='touchStart' bindtouchend='touchEnd'> <view wx:for="{{ground}}" wx:for-item="cols" class='ground-row'> <view wx:for="{{cols}}" class='ground-col'> <view class='block block{{item}}'></view> </view> </view> </view> <view class='content-top'> <view class='top-item top-score'> <view class='score-description'>得分</view> <view class='score-number'>{{score}}</view> </view> <view class='top-item top-start' bindtap='goStart'>START</view> <view class='top-item top-score'> <view class='score-description'>历史最高</view> <view class='score-number'>{{maxScore}}</view> </view> </view> </view>
2.WXSS
代码如下(示例):
/* pages/demo/snake/snake.wxss */ .content-top { display: flex; } .top-item { flex: 1; height: 150rpx; margin: 0 20rpx; line-height: 150rpx; text-align: center; border-radius: 16rpx; } .top-start { font-size: 22px; background: deepskyblue; color: #fff; } .top-score { background: #eee4da; } .score-description { line-height: 70rpx; } .score-number { line-height: 60rpx; } .content-bottom { display: flex; flex-direction: column; width: 660rpx; height: 840rpx; margin: 50rpx auto 0; } .ground-row { display: flex; } .ground-col { flex: 1; width: 30rpx; height: 30rpx; } .block { width: 100%; height: 100%; background: #eee; } .block1 { background: black; border-radius: 5px; } .block2 { background:red; border-radius: 5px; }
3.JS
代码如下(示例):
