小程序根據分值顯示進度（餅圖和進度條）

 

wxml:

  <view class="score">
        <!-- 餅圖 -->
        <view class="s_cookies">
          <canvas canvas-id="ringCanvas" class="canvas" bindtouchstart="touchHandler"></canvas>
          <image src="{{radarImg}}" style="width: 260rpx; height: 270rpx;" class="lucky-index-img" />
        </view>
        <!-- 進度條 -->
        <view class="s_progress">
          <view wx:for="{{series}}" wx:key="item.name">
            <text style="width:35%;">{{item.name}}</text>
            <progress class="s_prg" percent="{{item.data}}" border-radius="10" stroke-width="12" active-color="{{item.color}}" active/>
            <text>+{{item.data}}分</text>
          </view>
        </view>
      </view>

wxss:

.score{
    display: flex;
    justify-content: space-between;
}
.canvas{
   border:1rpx solid #f2f2f2;
    display: block;
    position: fixed;
    left: 9999rpx;
    z-index: 0;
     width: 260rpx;
    height: 270rpx; 
     padding: 0; 
}
.s_progress{
    margin-top: 80rpx;
    margin-right: 4%;
}
.s_progress text{
    width: 20%;
    font-size: 25rpx;
}
.s_progress view{
    display: flex;
}
.s_progress view:nth-child(4){
    display: none;
}
.s_prg{
    width: 170rpx;
    overflow: hidden;
    border-radius: 100px;

總結：留下一個記錄.........

1.分值餅圖使用了基於canvas的圖表插件wxCharts

 2.將傳過來的數據處理放進進度條對應的分值里面去
