如何在字符串中查找字符串数组？

I'd like to search a string for multiple strings, and return true if it finds any of them in there, false otherwise, something like this:

我想在一个字符串中搜索多个字符串，如果在那里找到任何字符串则返回true，否则返回false，如下所示：

var s = "thing1 thing2"
s.contains(["thing1","thing44444"]) // true
s.contains("1") // true
s.contains("x") // false

Here's what I have so far, but it's getting messier and doesn't really work:

这是我到目前为止所拥有的，但它变得更加混乱，并没有真正起作用：

String.prototype.contains = function(xv) {
    var t = this
    if(xv.isString()){ // isString/isArray are functions I made elsewhere in my code, they work.
        if(t.indexOf(xv) > -1)
            return true;
    } else if(xv.isArray()) {
        if(xv.contains(t)){
            return true
        }
        for(v in xv){
            if(t.indexOf(xv[v]) > -1){
                return true
            }
        }
    } else {
        return false
    }
}

As of now, it will return undefined if it makes it through the for loop without finding anything. I had return false after the for loop, but it would run before the for finished.

截至目前，它将返回undefined，如果它通过for循环而没有找到任何东西。我在for循环后返回false，但它会在for完成之前运行。

I feel like there's gotta be an easier way to do this.

我觉得必须有一个更简单的方法来做到这一点。

I've already tried How do you search multiple strings with the .search() Method? but I couldn't send an array to .search().

我已经尝试过如何使用.search（）方法搜索多个字符串？但我无法将数组发送到.search（）。

Frameworks I'm using: angular 1.5.8, jquery 1.11.1

You can use Array.some and String.indexOf or String.includes

您可以使用Array.some和String.indexOf或String.includes

var s1 = "thing1 thing2";
var s2 = "Hello Kitty";

var r1 = ["thing1","thing44444"].some( x => s1.includes(x));
var r2 = ["Travis","Heeeeeeter"].some( x => s2.includes(x));

console.log(r1, r2); // true, false
