[英]How to find an array of strings in a string?
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,如果在其中找到它们中的任何一个,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: 到目前为止,这是我所拥有的,但是它变得越来越杂乱,并不能真正起作用:
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. 到目前为止,如果它通过
for
循环而没有找到任何东西,它将返回undefined
。 I had return false
after the for
loop, but it would run before the for
finished. 我在
for
循环之后return false
,但是它将在for
结束之前运行。
I feel like there's gotta be an easier way to do this. 我觉得有一种更简单的方法可以做到这一点。
I've already tried How do you search multiple strings with the .search() Method? 我已经尝试过如何使用.search()方法搜索多个字符串? but I couldn't send an array to
.search()
. 但我无法将数组发送到
.search()
。
Frameworks I'm using: angular 1.5.8, jquery 1.11.1 我正在使用的框架: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
