【问题描述】：

我有字符串 "America" 我想将此字符串与可用字符串进行比较，即

"Depot Meridian - Turkey","IMP Logistics - Ukraine","Cryosite Depot - Australia","Thermo Fisher Scientific - Colombia","Fisher Singapore - Singapore","Fisher - Brazil - Brazil","Fisher Russia - Russia","Depot Meridian - Turkey","IMP Logistics - Ukraine","Cryosite Depot - Australia","Thermo Fisher Scientific - Colombia","Fisher Singapore - Singapore","Fisher - Brazil - Brazil","Fisher Russia - Russia"

这里每个字符串都由, 分隔，所以如果字符串“America”等于给定的字符串，我想返回 true 如何在 javascript 中执行此操作？

【问题讨论】：

将字符串存储在数组中，然后使用arr.some((str) => str.includes(word));
每个字符串都由, 分隔...当然，但是这些字符串在哪里？
这里没有具体的 React - 您还想获得“Bla bla - America”的正面评价还是只有“America”在列表中？
所以这是一个带有双引号和逗号的字符串？
这个sn-p是字符串数组还是单个字符串？

【解决方案1】：

你需要去掉双引号，然后用,分割并使用includes方法在数组内部搜索。

let string = '"Depot Meridian - Turkey","IMP Logistics - Ukraine","Cryosite Depot - Australia","Thermo Fisher Scientific - Colombia","Fisher Singapore - Singapore","Fisher - Brazil - Brazil","Fisher Russia - Russia","Depot Meridian - Turkey","IMP Logistics - Ukraine","Cryosite Depot - Australia","Thermo Fisher Scientific - Colombia","Fisher Singapore - Singapore","Fisher - Brazil - Brazil","Fisher Russia - Russia"'

let arr = string.replaceAll('"', '').split(',')

console.log(arr.includes('America'));
console.log(arr.includes('Thermo Fisher Scientific - Colombia'));
