Question

我有一个看起来像这样的数组：

var things = ["33bn", "2x", "Apple123"];

如何将该数组转换为：

var things = ["33", "bn", "2", "x", "Apple", "123"];

是否可以使用split和RegExp执行此操作？

我不知道该如何做到这一点，也许我可以循环遍历数组并使用RegExp拆分每个项目，然后将新数组的每个项目推入旧数组？

Answer 1

使用arrow-function ready browsers：

things.map(t => t.match(/\d+|[A-Za-z]+/g))
    .reduce((x, y) => x.concat(y));

＆＃13;

var things = ["33bn", "2x", "Apple123"];

var result = things.map(t => t.match(/\d+|[A-Za-z]+/g))
  .reduce((x, y) => x.concat(y));

console.log(result);

传播算子，箭头功能：

driver = GraphDatabase.driver("bolt://localhost",
                                 auth=basic_auth('neo4j', 'password'),
                                 encrypted=True,
                                 trust=TRUST_ON_FIRST_USE)
session = driver.session()

Answer 3

您可以像这样使用.reduce：

var things = ["33bn", "2x", "Apple123"];

things.reduce(function(item, i){
  return item.concat(i.match(/\d+|[A-Za-z]+/g));
}, []);

Answer 4

您可以使用forEach循环并将带有展开运算符...的项目附加到新列表中。

＆＃13;

var things = ["33bn", "2x", "Apple123"],
    other = [];
things.forEach(el=>other.push(...el.match(/\d+|[a-z]+/gi)));
console.log(other);

Answer 5

这将是我的解决方案

var things = ["33bn", "2x", "Apple123"];
things = things.reduce((p,c) => p.concat(c.match(/\d+|[a-z]+/ig)),[]);
console.log(things);
