如何檢查字符串是否包含JavaScript中預定義數組中存在的子字符串？

Question

找出JavaScript數組是否包含給定字符串的子字符串的最有效方法是什么？

例如，如果我有一個JavaScript數組

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

我需要將上述數組與字符串進行比較時返回true的條件：

"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

對於ES6：

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

Answer 3

萬一您不能使用ES6：

 let arr = ["John","Jerry","Ted"]; let str = "John Elton"; var match = arr.some(function (name) { return str.indexOf(name) > -1; }); console.log(match);
