检查字符串数组是否包含子字符串 [英] Check if an array of strings contains a substring

问题描述

我有一个像这样的数组:

I have an array like this:

array = ["123", "456", "#123"]

我想找到包含子字符串#" 的元素.我尝试了 array.includes(#")和 array.indexOf(#"")，但这没有用.

I want to find the element which contains the substring "#". I tried array.includes("#") and array.indexOf("#") but it didn't work.

如何检查此数组中的任何字符串是否包含子字符串#"" ?

How can I check if any of the strings in this array contain the substring "#"?

推荐答案

因为include会将'#'与每个数组元素进行比较.

Because includes will compare '#' with each array element.

让我们尝试使用一些或查找如果要查找是否要精确获取元素

Let's try with some or find if you want to find if you want to get exactly element

var array = ["123", "456", "#123"];

var el = array.find(a =>a.includes("#"));

console.log(el)
