switch使用（微信小程序）

switch可以理解为开关的使用，就是打开和闭合。switch开是true，闭是false，也可以绑定函数，在绑定函数中获取当前状态是开还是闭，然后根据自己的逻辑写代码。
wxxml

<view class="section">
    <view class="section-title">灯</view>
      <view class="section-form">
        <view class="form-group">
          <label>灯的控制</label>
          <!--checked默认是true bindchange可以绑定函数-->
          <switch   color="#007aff" checked bindchange="light"  ></switch>
        </view>
      </view>      
</view>

js
对应上面的light函数，通过e.detail.value拿到当前的状态是true还是false然后写逻辑代码，我这是控制灯（树莓派）

  //灯  26  high1 low1
  light(e){
  		//拿到状态
       var status=e.detail.value
       做判断
       if(status==true){
            console.log("开灯")
            //向后台发送请求
            wx.request({
               url: 'http://localhost:8080/lg/sshlinuxController/jqcontrol',
               data: {
                 com: "python high1.py"
               }
             })
       }else{
          console.log("关灯")
          wx.request({
               url: 'http://localhost:8080/lg/sshlinuxController/jqcontrol',
               data: {
                 com: "python low1.py"
               }
             })
       }
  },

wxcss
想用这里的代码我把css也分享给大家
