Question

比方说，我们要检查speech是否包含特定句子（reference）但在其末尾：

这里是reference：

let reference = "have you ever look at someone";

基于此reference，我们想比较speech并返回匹配或不匹配：

let speech = "blaaaah have you ever look at someone"; // Match because 'have you ever look at someone' is at the end of speech
let speech = "have you ever look at someone blaaaah"; // No match because something else came after 'have you ever look at someone'

问题是我无法区分上述语音示例，并且代码始终返回Match：

//let speech = "blaaaah have you ever look at someone"; // matched
let speech = "have you ever look at someone blaaaah"; // No match 

let reference = "have you ever look at someone";

if(new RegExp("\\b"+reference+"\\b").test(speech)){
  console.log("Finally Matched!")
} else {
  console.log("No Match At Last!")
}

Answer 1

这是您要找的吗？

//let speech = "blaaaah have you ever look at someone"; // matched
let speech = "have you ever look at someone blaaaah"; // No match 

let reference = "have you ever look at someone";

if(new RegExp("\\b"+reference+"\\b$").test(speech)){
  console.log("Finally Matched!")
} else {
  console.log("No Match At Last!")
}

Answer 2

您可以使用"s3://my-bucket/veryCoolFile.img"进行以下验证，

endsWith

以您的情况

var str = "Hello world, welcome to the universe.";
var n = str.endsWith("universe.");

仅在字符串末尾匹配整个句子
