用于在JavaScript中反转数组的代码失败

Question

var fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits = fruits.sort();
document.write(fruits);
for(var i = 0; i < Math.ceil(fruits.length / 2); i++) {
    var temp = fruits[i];
    fruits[i] = fruits[fruits.length - 1 - i];
    fruits[fruits.length - 1 - i] = temp;
}
document.write(fruits);

I'm trying to make a reverse of the ordered (az) array fruits, in order to make it za in the for loop. Why isn't this working?

Answer 1

只需使用.reverse() 。

fruits.reverse();
