如何检查字符串是否包含JavaScript中预定义数组中存在的子字符串？

Question

找出JavaScript数组是否包含给定字符串的子字符串的最有效方法是什么？

例如，如果我有一个JavaScript数组

var a = ["John","Jerry","Ted"];

在将上述数组与字符串进行比较时，我需要返回true的条件：

"John Elton"

Answer 1

您可以使用.some()和.includes()方法：

let arr = ["John","Jerry","Ted"];
let str = "John Elton";

let checker = (arr, str) => arr.some(s => str.includes(s));

console.log(checker(arr, str));

Answer 2

对于ES6：

var array = ["John","Jerry","Ted"];
var strToMatch = "John Elton"
array.some(el => strToMatch.includes(el))

Answer 3

如果您不能使用ES6：

>>> from itertools import islice
>>> l1=[1,2,3,4,5,7,8,9,23,32,33] 
>>> l2=[5,3,1,2]
>>> it = iter(l1)
>>> [list(islice(it, n)) for n in l2]
[[1, 2, 3, 4, 5], [7, 8, 9], [23], [32, 33]]
