javascript - 正则表达式需要匹配字符串中的第一个路径而不是后续

Question

我正在寻找匹配第一行但不匹配第二行的正则表达式。这就是我的/^github.com\/[^\\\n]+$/

github.com/reggi
github.com/reggi/example

https://regexr.com/3ld7o

var patternA = /^github.com\/[^\\\n]+$/
var patternB = /^github\.com\/.+/
var patternC = /^github.com\/[^\/\n]+$/

var examples = function (pattern) {
  return [
    !!'github.com/reggi/genesis/soup'.match(pattern),
    !!'github.com/reggi/genesis'.match(pattern),
    !!'github.com/reggi'.match(pattern),
  ]
}

console.log(examples(patternA))
console.log(examples(patternB))
console.log(examples(patternC))

^github.com\/[^\/\n]+$

我认为您只是转义了错误类型的斜杠。
