只是想知道,是否有一种方法可以向.includes方法添加多个条件,例如:
var value = str.includes("hello", "hi", "howdy");
想象一下逗号表示“或”。
它现在询问字符串是否包含hello, hi或howdy。所以只有当其中一个条件为真。
有什么方法可以做到吗?

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

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(' ')))
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"]
这是一个有争议的选择:
String.prototype.includesOneOf = function(arrayOfStrings) {
if(!Array.isArray(arrayOfStrings)) {
throw new Error('includesOneOf only accepts an array')
}
return arrayOfStrings.some(str => this.includes(str))
}
允许你做以下事情:
'Hi, hope you like this option'.toLowerCase().includesOneOf(["hello", "hi", "howdy"]) // True
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);
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
