Question

以下是字段值的要求应该是 - 否则它应该生成错误

格式为9个字符，2个字母，后跟6个数字，接着是一个字母

e.g。＆＃39; AB332211C＆＃39;

任何其他值都应使用JavaScript生成错误消息。任何人都可以帮助我为此创建正则表达式。

编辑：直到我完成了这项工作：帮助改进相同

示例：

// Common regexs
  var regexEmail = /^([\w]+)(.[\w]+)*@([\w]+)(.[\w]{2,3}){1,2}$/;
  var regexUrl = /^(http:\/\/www.|https:\/\/www.|ftp:\/\/www.|www.){1}([\w]+)(.[\w]+){1,2}$/;

  var regexIP = /^((25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.){3}(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])$/;
  var regexInteger = /(^-?\d\d*$)/; **

Answer 1

/\b[A-z]{2}[0-9]{6}[A-z]{1}$/.test('AB332211C')

Answer 2

这会有所帮助..

/^[ ]*([a-zA-Z]{2}\d{6}[a-zA-Z])[ ]*$/

[a-zA-Z]{2}匹配两个字母字符

\d{6}匹配后续的6位数字

[a-zA-Z]匹配一个字母字符

Answer 3

/ ^（[A-ZA-Z] {2} \ d {6} [A-ZA-Z]）$ /

1st Capturing group ([a-zA-Z]{2}\d{6}[a-zA-Z])
[a-zA-Z]{2} match a single character present in the list below

Quantifier: {2} Exactly 2 times
a-z a single character in the range between a and z (case sensitive)
A-Z a single character in the range between A and Z (case sensitive)

\d{6} match a digit [0-9]
Quantifier: {6} Exactly 6 times

[a-zA-Z] match a single character present in the list below
a-z a single character in the range between a and z (case sensitive)
A-Z a single character in the range between A and Z (case sensitive)
$ assert position at end of the string
