我有一个像下面这样的字符串。
const a = "The school is big."
我想进行搜索。
function searching(q){
...
}
// searching(the) -> true
// searching(e s) -> true
// searching(oolis) -> true
// searching(the big) -> false
您能为这种情况推荐一些解决方案吗？

如果使用.replace()从输入字符串和搜索字符串中删除空格，并使用toLowerCase()将其都转换为小写，则可以使用.includes()方法检查是否您的搜索字符串在输入字符串之内：
const a = "The school is big.";
function searching(str,q) {
const str_no_space = str.replace(/\s+/g,'').toLowerCase();
const q_no_space = q.replace(/\s+/g,'').toLowerCase();
return str_no_space.includes(q_no_space);
}
console.log(searching(a,"the")); // -> true
console.log(searching(a,"e s")); // -> true
console.log(searching(a,"oolis")); // -> true
console.log(searching(a,"the big")); // -> false,
使用includes()和toUpperCase()进行不区分大小写的字符串比较。
const a = "The school is big."
function searching(q){
return a.toUpperCase().includes(q.toUpperCase());
}
console.log(searching('the'));
console.log(searching('e s'));
console.log(searching('oolis'));
console.log(searching('the big'));
