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
借鉴T.J. Crowder的解决方案，我创建了一个原型来处理这个问题:
Array.prototype.check = function (s) {
return this.some((v) => {
return s.indexOf(v) >= 0;
});
};
其他回答
let obj = [{name : 'amit'},{name : 'arti'},{name : 'sumit'}];
let input = 'it';
使用滤镜:
obj.filter((n)=> n.name.trim().toLowerCase().includes(input.trim().toLowerCase()))
function containsAny(str, substrings) {
for (var i = 0; i != substrings.length; i++) {
var substring = substrings[i];
if (str.indexOf(substring) != - 1) {
return substring;
}
}
return null;
}
var result = containsAny("defg", ["ab", "cd", "ef"]);
console.log("String was found in substring " + result);
substringsArray.every(substring=>yourBigString.indexOf(substring) === -1)
全力支持;)
Javascript函数使用搜索字符串或搜索字符串数组搜索标签或关键字数组。(使用ES5的一些数组方法和ES6的箭头函数)
// returns true for 1 or more matches, where 'a' is an array and 'b' is a search string or an array of multiple search strings
function contains(a, b) {
// array matches
if (Array.isArray(b)) {
return b.some(x => a.indexOf(x) > -1);
}
// string match
return a.indexOf(b) > -1;
}
使用示例:
var a = ["a","b","c","d","e"];
var b = ["a","b"];
if ( contains(a, b) ) {
// 1 or more matches found
}
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>
