var bmi = weight/(height*height); if(bmi <= 18.5){ console.log("过轻"); } else if(bmi >18.5 && bmi < 25){ console.log("正常"); } else if(bmi >= 25 && bmi < 28){ console.log("过重"); } else if(bmi >= 28 && bmi < 32){ console.log("肥胖"); } else{ console.log("过于肥胖"); }

var height=1.75; var weight=80.5; var bmi = weight/(height*height); if (bmi>32){ console.log('严重肥胖'); }else if(bmi>28){ console.log('肥胖'); }else if（bmi>25){ console.log('过重'）; }else if(bmi>18.5){ console.log('正常'); }else{ console.log('过轻') } 这么写哪里有问题？怎么报错啊？

}else if（bmi>25){ //半括号格式问题报错 console.log("过重"）; //半括号格式问题报错

括号用的中文的（）所以报错，应该用英文的();

切换大写输入比切换输入法更快，哈哈，看来笔记本要默认英文用来学习，输入法都不装了。
