将以下代码用javascript的方法实现import sys import math STATION_ICON_SIZE = 90 PILE_ICON_SIZE = 40 PILE_X_OFFSET = 200 ROW_RATE = 3 COL_RATE = 10 def matrix(n): if n < (ROW_RATE * COL_RATE): r = math.ceil(n / COL_RATE) else: r = math.floor(ROW_RATE * ((n / (ROW_RATE * COL_RATE)) ** 0.5)) c = math.ceil(n / r) return r, c def station_pos(r): A = (STATION_ICON_SIZE + PILE_ICON_SIZE) // 2 B = (STATION_ICON_SIZE - PILE_ICON_SIZE) // 2 return (0, (r - 1) * A - B) def pile_pos(c, n): A = STATION_ICON_SIZE + PILE_ICON_SIZE lst = [] for i in range(n): x = (i % c) * A + PILE_X_OFFSET y = (i // c) * A lst.append((x, y)) return lst def link(c, n): lst = [] for i in range(n): lst.append(((i - 1) if i % c != 0 else -1, i)) return lst def main(): if len(sys.argv) < 2: print("test.py <n>") return n = int(sys.argv[1]) r, c = matrix(n) print(station_pos(r)) print(pile_pos(c, n)) print(link(c, n)) if __name__ == '__main__': main()

以下是将给定代码用JavaScript实现的示例:
```javascript
const STATION_ICON_SIZE = 90;
const PILE_ICON_SIZE = 40;
const PILE_X_OFFSET = 200;
const ROW_RATE = 3;
const COL_RATE = 10;
function matrix(n) {
if (n < ROW_RATE * COL_RATE) {
r = Math.ceil(n / COL_RATE);
} else {
r = Math.floor(ROW_RATE * Math.pow(n / (ROW_RATE * COL_RATE), 0.5));
}
c = Math.ceil(n / r);
return [r, c];
}
function station_pos(r) {
const A = (STATION_ICON_SIZE + PILE_ICON_SIZE) / 2;
const B = (STATION_ICON_SIZE - PILE_ICON_SIZE) / 2;
return [0, (r - 1) * A - B];
}
function pile_pos(c, n) {
const A = STATION_ICON_SIZE + PILE_ICON_SIZE;
const lst = [];
for (let i = 0; i < n; i++) {
const x = (i % c) * A + PILE_X_OFFSET;
const y = Math.floor(i / c) * A;
lst.push([x, y]);
}
return lst;
}
function link(c, n) {
const lst = [];
for (let i = 0; i < n; i++) {
lst.push([(i - 1) % c !== 0 ? i - 1 : -1, i]);
}
return lst;
}
function main() {
const args = process.argv.slice(2);
if (args.length < 1) {
console.log("test.js <n>");
return;
}
const n = parseInt(args[0]);
const [r, c] = matrix(n);
console.log(station_pos(r));
console.log(pile_pos(c, n));
console.log(link(c, n));
}
main();
```
请注意,由于JavaScript的一些不同之处,我进行了一些更改:
- 在函数定义之前声明了常量和变量。
- 将Python的元组转换为JavaScript数组。
- 将Python的整数除法替换为JavaScript的Math.floor函数。
- 在link函数中使用了JavaScript的三元运算符代替Python的if/else语句。
- 删除了检查sys.argv的代码,改为使用process.argv。
请根据您的具体需求进行调整。
