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
   }
}

基于t。j。克劳德的答案

使用转义的RegExp测试至少一个子字符串的“至少一次”出现。

函数buildSearch(substrings) { 返回新的RegExp( 子字符串 . map(函数(s) {s.replace返回 (/[.*+?^${}()|[\]\\]/ g , '\\$&');}) .join('{1，}|') + '{1，}' ）; ｝ var pattern = buildSearch(['hello'，'world']); console.log(模式。测试('你好')); console.log(模式。Test ('what a wonderful world')); console.log(模式。Test ('my name is…'));

单线解决方案

substringsArray.some(substring=>yourBigString.includes(substring))

如果子字符串存在\不存在，则返回true\false

需要ES6支持

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
   }
}

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()))

substringsArray.every(substring=>yourBigString.indexOf(substring) === -1)

全力支持;)
