恢复可以用markdown么？

```javascript
/* 生成一个分页数组，以from开始，num个元素 */
function getArrOfNum(num, from) {
from = from || 1;

var arr = new Array(num),
i = from,
len = arr.length + from;

for (; i < len; i++) {
arr[i - from] = i;
};

return arr;
}

/* 当页数改变时，适用于ajax分页 */
function toPage(count/* 总页数 */, current/* 当前页*/, max/* 显示的最多页数 */) {
var pages,//最后得到的分页元素
from = current - Math.floor(max/2),//当前页的前面页数
to = current + Math.floor(max/2) - 1;//当前页的后面页数

if (count > max && from >= 1) {

if (to <= count) {
pages = getArrOfNum(max, from);
} else {
pages = getArrOfNum(max, from - (to - count));
};

} else { // 少于等于max页，直接返回
pages = getArrOfNum(count > max ? max : count);
};
return pages;
}
toPage(15, 7, 5);
```
