用于移动号码验证的正则表达式

Question

我想要一个用于手机号码验证的正则表达式.正则表达式应该是这样的,它必须+只在开始时才接受,并且-只有在国家代码之后才允许空格(或)(仅一次).国家代码后只允许10位数字.国家代码应该是可选的.如果是国家代码不存在,它应该只接受10位数字.Regex应该防止任何无效的数字,如(例如:+91 0000000000或0000000000).

正则表达式应该接受像这样的数字

__PRE__

Answer 1

如果您使用下面介绍的技巧,请满足您的所有要求

正则表达式: /^(\+\d{1,3}[- ]?)?\d{10}$/

1. ^ 行的开始
2. A +后跟\d+一个 or -哪个是可选的.
3. 整点二是可选的.
4. 否定前瞻以确保0不遵循.
5. 匹配\d+10次​​.
6. 行结束.

DEMO ^{在演示中添加了multiline标志以检查所有情况}

PS你真的需要指定你使用的语言,以便使用if下面的条件:

// true if above regex is satisfied and (&&) it does not (`!`) match `0`s `5` or more times

if(number.match(/^(\+\d{1,3}[- ]?)?\d{10}$/) && ! (number.match(/0{5,}/)) )

Answer 2

这个正则表达式非常简短而且适合工作。

/^([+]\d{2})?\d{10}$/

例如：+910123456789 或 0123456789

-> /^ and $/ is for starting and ending
-> The ? mark is used for conditional formatting where before question mark is available or not it will work
-> ([+]\d{2}) this indicates that the + sign with two digits '\d{2}' here you can place digit as per country
-> after the ? mark '\d{10}' this says that the digits must be 10 of length change as per your country mobile number length

这就是这个手机号码正则表达式的工作方式。
+ 符号用于数字的全球匹配。

如果你想在中间添加空格，那么你可以使用

[ ]

这里方括号表示字符序列，空格是用于在正则表达式中搜索的字符。
对于空格分隔的数字，您可以使用此正则表达式

/^([+]\d{2}[ ])?\d{10}$/

例如：+91 0123456789

谢谢，如果你有任何问题。

Answer 3

试试这个正则表达式：

^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$

使用Perl的YAPE对正则表达式的解释如下：
