测试字符串是否与正则表达式匹配？

Question

我需要检查字符串是否与正则表达式匹配。

function isEqual(str)
{
  var re = /\/users\/(.+)/;
  
  // code
}

// Some examples of requests

console.log(isEqual('/users/1'));
console.log(isEqual('/users/1/Nikita'));
console.log(isEqual('/users'));

Answer 1

您可以使用 test 方法来获取布尔值

function isEqual(str)
{
  return /\/users\/(.+)/.test(str);
  
  // code
}

// Some examples of requests

console.log(isEqual('/users/1'));
console.log(isEqual('/users/1/Nikita'));
console.log(isEqual('/users'));

Answer 2

我认为此正则表达式有效

function isEqual(str)
{
  return /\/users((\/\d+){1}(\/[A-Za-z0-9]+){0,1}){0,1}/.test(str);

  // code
}

// Some examples of requests

console.log(isEqual('/users/1'));
console.log(isEqual('/users/1/Nikita'));
console.log(isEqual('/users'));
