与数组数据/的精确匹配

const dataArray = ["amoos"， "rifat"， "hello"]; const findId = (data, id) => { 让res = data。Find (el => el == id) 返回res ?真:假; ｝ console.log(findId(dataArray， 'Hi')) // false console.log(findId(dataArray， 'amoos')) // true

这可以通过使用Array和RegEx的一些/每个方法来完成。

检查list(array)中的所有单词是否存在于字符串中:

const multiSearchAnd = (text, searchWords) => (
  searchWords.every((el) => {
    return text.match(new RegExp(el,"i"))
  })
)

multiSearchAnd("Chelsey Dietrich Engineer 2018-12-11 Hire", ["cle", "hire"]) //returns false
multiSearchAnd("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "hire"]) //returns true

检查list(array)中的任何单词是否存在于字符串中:

const multiSearchOr = (text, searchWords) => (
  searchWords.some((el) => {
    return text.match(new RegExp(el,"i"))
  })
)

multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "hire"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["aaa", "hire"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["che", "zzzz"]) //returns true
multiSearchOr("Chelsey Dietrich Engineer 2018-12-11 Hire", ["aaa", "1111"]) //returns false

你也可以这样做:

Const STR = "hi, there" Const res = str.includes("hello") || str.includes("hi") || str.includes('howdy'); console.log (res);

只要其中一个include返回真值，value就为真，否则，它就为假。这在ES6中工作得非常好。

不是最好的答案，也不是最干净的答案，但我认为它更宽容。 比如，如果你想对所有的支票使用相同的过滤器。 实际上.filter()与数组一起工作并返回一个过滤后的数组(我发现这也更容易使用)。

var str1 = 'hi, how do you do?';
var str2 = 'regular string';
var conditions = ["hello", "hi", "howdy"];

// Solve the problem
var res1 = [str1].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));
var res2 = [str2].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));

console.log(res1); // ["hi, how do you do?"]
console.log(res2); // []


// More useful in this case
var text = [str1, str2, "hello world"];

// Apply some filters on data
var res3 = text.filter(data => data.includes(conditions[0]) && data.includes(conditions[2]));
// You may use again the same filters for a different check
var res4 = text.filter(data => data.includes(conditions[0]) || data.includes(conditions[1]));

console.log(res3); // []
console.log(res4); // ["hi, how do you do?", "hello world"]

扩展字符串本机原型:

if (!String.prototype.contains) {
    Object.defineProperty(String.prototype, 'contains', {
        value(patterns) {
            if (!Array.isArray(patterns)) {
                return false;
            }

            let value = 0;
            for (let i = 0; i < patterns.length; i++) {
                const pattern = patterns[i];
                value = value + this.includes(pattern);
            }
            return (value === 1);
        }
    });
}

允许你做以下事情:

console.log('Hi, hope you like this option'.toLowerCase().contains(["hello", "hi", "howdy"])); // True

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));
