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

问题描述

我对这项任务有些困惑 我有一个像这样的数组: 数组= ["123"，"456"，#123"] 我想找到包含#的元素.我使用了array.includes("#")和array.indexOf("#")，但是没有用 有什么想法吗?

i'm a little bit confused with this task I have an array like this: array = ["123", "456", "#123"] i want to find the element which contains the #. I used array.includes("#") and array.indexOf("#") but it didn't work Any ideas??

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)
