即使有且只有一个条件为真，它也能工作:

var str = "bonjour le monde vive le javascript";
var arr = ['bonjour','europe', 'c++'];

function contains(target, pattern){
    var value = 0;
    pattern.forEach(function(word){
      value = value + target.includes(word);
    });
    return (value === 1)
}

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

你可以这样做

["hello", "hi", "howdy"].includes(str)

使用includes()，没有，但你可以通过test()实现REGEX:

var value = /hello|hi|howdy/.test(str);

或者，如果词语来自动态来源:

var words = ['hello', 'hi', 'howdy'];
var value = new RegExp(words.join('|')).test(str);

REGEX方法是一个更好的主意，因为它允许您将单词匹配为实际单词，而不是其他单词的子字符串。你只需要边界标记\b这个词，那么:

var str = 'hilly';
var value = str.includes('hi'); //true, even though the word 'hi' isn't found
var value = /\bhi\b/.test(str); //false - 'hi' appears but not as its own word

const givenArray = ['Hi, how are you'， 'how are you'， 'howdy, how you doing'] const includeValues = ["hello"， "hi"， "howdy"] const filteredStrArray = givenArray。filter(str => includeValues)str.toLowerCase().includes(value))) console.log (filteredStrArray);

也许晚了，但这里是我的解决方案为一个数组和两个或更多的项目 / 1 | 2 /。Test (['one'， 'two'， 'three'， 'four']。加入(' '))

console.log(/ 1 | 2 /。Test (['one'， 'two'， 'three'， 'four']。加入(' ')))

1线路方案:

字符串/ Array.prototype。包括('hello' || 'hi' || 'howdy');

let words = 'cucumber, mercy, introduction, shot, howdy'
words.includes('hi' || 'howdy' || 'hello') // true
words.includes('hi' || 'hello') // false
