原生JS与CSS实现软件卸载对话框功能

aiguangyuan 人气:0

今天给大家分享一个特别有意思的软件卸载对话框，鼠标在整个对话框里移动时，中间的人脸会作出不同的变化，当鼠标悬停到“保留”按钮上时，人脸的表情会变得开心，当鼠标悬停到“卸载”按钮上面时，人脸的表情会变得不开心。

实现效果如下：

实现代码如下，首先是HTML：

<!DOCTYPE html>
<html lang="en">

    }
    boi.style.setProperty(`--${prop}`, current[prop]);
  }
  requestAnimationFrame(update);
}
 
update();
