非常直截了当。在javascript中，我需要检查字符串是否包含数组中持有的任何子字符串。
当前回答
var str = "A for apple" var subString = ["apple"] console.log (str.includes (subString))

你可以这样检查:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var list = ["bad", "words", "include"]
var sentence = $("#comments_text").val()
$.each(list, function( index, value ) {
if (sentence.indexOf(value) > -1) {
console.log(value)
}
});
});
</script>
</head>
<body>
<input id="comments_text" value="This is a bad, with include test">
</body>
</html>
var yourstring = 'tasty food'; // the string to check against
var substrings = ['foo','bar'],
length = substrings.length;
while(length--) {
if (yourstring.indexOf(substrings[length])!=-1) {
// one of the substrings is in yourstring
}
}
const str = '此字符串是否包含下面数组中的一个或多个字符串?'; Const arr = ['one'， 'two'， 'three']; Const包含= arr。Some (element => { If (str.includes(element)) { 返回true; ｝ 返回错误; })； console.log(包含);/ /正确的
var str = "A for apple" var subString = ["apple"] console.log (str.includes (subString))
这太迟了，但我刚刚遇到了一个问题。在我自己的项目中，我使用以下方法来检查字符串是否在数组中:
["a","b"].includes('a') // true
["a","b"].includes('b') // true
["a","b"].includes('c') // false
通过这种方式，你可以获取一个预定义数组并检查它是否包含字符串:
var parameters = ['a','b']
parameters.includes('a') // true
