本次只分享小程序端的代码实现，后端每个人都有自己的实现方法，就不写在此。

好了，先看实现样式：

本次投票实现需要一个页面和一个弹窗实现，我们做的是淘汰赛部分，在此，黄啊码将淘汰赛部分直接选用选择队伍投票方式，比分这块实现方式其实也类似：

 那就先走第一个图吧，wxml如下：

<view  class="contain item">
    <view wx:for="{{all_list}}" wx:key="index"  wx:for-item="item" style="border-bottom: 1px solid #36a2e6;">
      <view class="date">
        <view class="game-type">
        <text>淘汰赛</text>
        </view>
        <text>2022-12-15</text>
        <view>猜中积分<text style="color: rgb(255, 26, 26);font-weight: bold;">+500}</text></view>
      </view>
      <view class="guess_item">
        <view class="time">
          <text space="nbsp">12月15日 03:00半决赛</text>
        </view>
        <view class="country">
          <view class="country-item">
            <text space="emsp">法国 </text>
            <image src="{{img_url+item.country_flag1}}" />
          </view>
          <view class="vs">VS</view>
          <view class="country-item diff">
            <image src="{{img_url+item.country_flag2}}" />
            <text space="emsp">摩洛哥</text>
          </view>
        </view>
        <view class="btn_box">
          <button>参与竞猜</button>
        </view>
        
        <view class="result">
          <view class="pre-item">
            <span>我的预测</span>
            <view>
              <text space="ensp" style="color: #3c3c3c;">---</text>
            </view>
          </view>
          <view class="line"></view>
          <view class="pre-item">
            <view>未参与竞猜</view>
          </view>
        </view>
      </view>
    </view>
    </view>
</view>

wxss如下： 【对应颜色有做调整，别顾着照抄哦】

  transform: translateX(-50%);
  text-align: center;
  font-size: 28rpx;
  color: rgb(255, 26, 26);
}

接下来是弹出窗体的wxml代码和wxss代码

<view class="choose_box">

    <view bindtap="chooseFn" class="left {{is_choose1?'choose_color':''}}" data-id="1">猜TA胜</view>

    <view bindtap="chooseFn" class="{{is_choose2?'choose_color':''}}" data-id="2">平局</view>

    <view bindtap="chooseFn" class="right {{is_choose3?'choose_color':''}}"  data-id="3" >猜TA胜</view>

  </view>

.choose_box {

  display: flex;

  justify-content: center;

}

.choose_box view {

  width: 178rpx;

  height: 74rpx;

  line-height: 74rpx;

  background-color: #fff;

  margin: 0 1rpx;

  text-align: center;

  border:2rpx solid #36a2e6;

  color: #36a2e6;

}

.choose_box .choose_color {

  background-color: #36a2e6;

  color: #fff;

}

.choose_box .left{

 border-top-left-radius: 22rpx;

 border-bottom-left-radius: 22rpx;

}

.choose_box .right{

  border-top-right-radius: 22rpx;

  border-bottom-right-radius: 22rpx;

}

最后实现的时候别忘了把点击事件加上

这里的dataset.id表示的是你选中的国家id，我在上边代码就直接省略了，毕竟每个认对于变量的命名都有所不同。

chooseFn(e) {
    if(e.currentTarget.dataset.id=="1") {
      this.setData({
        is_choose1:true,
        is_choose2:false,
        is_choose3:false,
       })
    }
    else if(e.currentTarget.dataset.id=="2") {
      this.setData({  
        is_choose1:false,
        is_choose2:true,
        is_choose3:false,
      })
    }
    else if(e.currentTarget.dataset.id=="3") {
      this.setData({  
        is_choose1:false,
        is_choose2:false,
        is_choose3:true,
      })
    }
    },

至于如何弹窗和关闭事件这个部分，我相信大多数只要入门过小程序的都知道，我就不一一阐述了，如果再不懂直接扣我也行。

好了，今天的分享就这里，有问题的留个言，别忘了一键三连，下次我们还会再见！

我是黄啊码，码字的码，退。。。退。。。退。。。朝！
