以下是用 JavaScript 实现您的要求的代码:
```javascript
const scores = [
{ number: 'N10471', chinese: 95, math: 79, english: 98 },
{ number: 'N1176', chinese: 84, math: 72, english: 76 },
{ number: 'N1087', chinese: 77, math: 89, english: 70 },
{ number: 'N18081', chinese: 93, math: 79, english: 71 },
{ number: 'N1365', chinese: 90, math: 91, english: 91 },
{ number: 'N1416', chinese: 74, math: 89, english: 85 },
{ number: 'N1048', chinese: 74, math: 82, english: 85 },
{ number: 'N1126', chinese: 77, math: 77, english: 85 },
{ number: 'N13861', chinese: 90, math: 74, english: 99 },
{ number: 'N1869', chinese: 90, math: 74, english: 99 },
];
// 计算每个人的总分,并按总分排名输出学号和总分
const totalScores = scores.map((student) => {
const total = student.chinese + student.math + student.english;
return { number: student.number, total };
}).sort((a, b) => b.total - a.total);
console.log('按总分排名输出学号和总分:');
totalScores.forEach((student, index) => {
console.log(`${index + 1}. 学号: ${student.number}, 总分: ${student.total}`);
});
// 统计各单科成绩的前三名,并输出对应的学号和成绩
const topChinese = scores.sort((a, b) => b.chinese - a.chinese).slice(0, 3);
console.log('语文前三名:');
topChinese.forEach((student) => {
console.log(`学号: ${student.number}, 成绩: ${student.chinese}`);
});
const topMath = scores.sort((a, b) => b.math - a.math).slice(0, 3);
console.log('数学前三名:');
topMath.forEach((student) => {
console.log(`学号: ${student.number}, 成绩: ${student.math}`);
});
const topEnglish = scores.sort((a, b) => b.english - a.english).slice(0, 3);
console.log('英语前三名:');
topEnglish.forEach((student) => {
console.log(`学号: ${student.number}, 成绩: ${student.english}`);
});
```
以上代码会先计算每个人的总分,并按总分排名输出学号和总分,然后统计各单科成绩的前三名,并输出对应的学号和成绩。
