如何使用JavaScript在数组中查找特定单词？
要查找数组中的特定单词，可以使用include()。我们有以下数组-
var sentence = ["My Name is John Smith. My Favourite Subject is JavaScript. I live in US. I like Hockey"];
现在，下面是一个数组，其中包含我们需要在上述“句子”数组中搜索的单词-
var keywords = ["John", "AUS", "JavaScript", "Hockey"];
示例
以下是代码-
var keywords = ["John", "AUS", "JavaScript", "Hockey"];
var sentence = ["My Name is John Smith. My Favourite Subject is JavaScript. I live in US. I like Hockey"];
const matched = [];
for (var index = 0; index < sentence.length; index++) {
for (var outerIndex = 0; outerIndex < keywords.length; outerIndex++) {
if (sentence[index].includes(keywords[outerIndex])) {
matched.push(keywords[outerIndex]);
}
}
}
console.log("The matched keywords are==");
console.log(matched);要运行上述程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo226.js。
输出结果
输出如下-
PS C:\Users\Amit\JavaScript-code> node demo226.js The matched keywords are== [ 'John', 'JavaScript', 'Hockey' ]
