Javascript 单仪表板电话号码-正则表达式验证

我需要一个简单的正则表达式来验证形式为x-y的电话号码，其中x和y可以表示任意数量的数字，破折号是可选的，但如果它确实出现，则大多数都在字符串中（破折号必须在其左右两侧有数字）

/^\d+（？：-\d+）$/

应该可以做到这一点。

/^\d+（\d+）$/）似乎有效。它匹配一个或多个前导数字，并带有可选的“连字符后跟一个或多个数字”

给出：

$ ./phone.pl 
"1-2" is a phone number
"-12" is NOT a phone number
"12-" is NOT a phone number
"123-1234" is a phone number
"1-" is NOT a phone number
"-1" is NOT a phone number
"123" is a phone number
"1" is a phone number
"foo-bar" is NOT a phone number
"12foo34" is NOT a phone number
"foo12-34" is NOT a phone number
"12f-o34" is NOT a phone number

可能会发布到目前为止您做了什么？“1foobar”将被匹配，您应该约束字符串的开始和结束^…$@CMS：可能是真的，尽管iulianchira可能希望将其合并到更大的regexp中。调整答案。

$ ./phone.pl 
"1-2" is a phone number
"-12" is NOT a phone number
"12-" is NOT a phone number
"123-1234" is a phone number
"1-" is NOT a phone number
"-1" is NOT a phone number
"123" is a phone number
"1" is a phone number
"foo-bar" is NOT a phone number
"12foo34" is NOT a phone number
"foo12-34" is NOT a phone number
"12f-o34" is NOT a phone number
