正则表达式 - 匹配除其他 numbers/letters 以外的任何字符之间的数字
Regex - match a number in-between any character except other numbers/letters
我正在努力寻找正则表达式...
所以我有一个产品 ID 9984
我正在尝试创建一个正则表达式 (Javascript)。
以下示例应该匹配：
9984
"9984"
'9984'
9984 //i.e. spaces are OK
以下示例 不应 匹配（即 9984 两边有数字或字母 [a-zA-Z0-9]）：
a9984
9984x
z9984B
199841
299842
99843
499844
Q9984c
etc.
我正在尝试正则表达式 /[^0-9]?9984?[^0-9]+/ 在：

\b9984\b

There are three different positions that qualify as word boundaries:
Before the first character in the string, if the first character is a word character.
After the last character in the string, if the last character is a word character.
Between two characters in the string, where one is a word character and the other is not a word character.
