反向香草JavaScript中的多个单词

标签: javascript arrays reverse

我有以下列表,并希望颠倒单词的顺序,而不是单词中每个字母的顺序。我目前有这个,但它是反转每个字母,而不是单词的顺序。

JS:

let items = ["Litte Bike, Tall Tree, Toy Car, Fast Car"].toString();
myArray.split("").reverse().join('')

当前输出:

raC tsaF ,raC yoT ,eerT llaT ,ekiB ettiL

所需的输出:

Bike Litte 
Tree Tall 
Car Toy 
Car Fast

您要先用逗号分割,然后再对新项目数组中的每个单词进行分割,然后颠倒这些项目。

您不想颠倒整个过程。

let items = ["Litte Bike, Tall Tree, Toy Car, Fast Car"].toString();

let result = items.split(',').map(item => item.split(' ').reverse().join(' ').trim());

console.log(result);

尝试一下

let items = ["Litte Bike, Tall Tree, Toy Car, Fast Car"];


let revItems = items.map(item => item.split(" ").reverse().join(" "));

console.log(revItems.reverse())

正如其他人所述,您必须先拆分元素,然后再拆分每个元素中的各个空格,然后反向打印。
