RegEx精确匹配字符串的开头和结尾，中间使用通配符

Question

I am searching strings with the following format: ABC-001

I would to construct a RegEx search from a user text input field so that I can search:

ABC* and match ABC-001, ABC-002, and so on...
ABC*2 and match ABC-002 but NOT ABC-012
ABC*12 and match ABC-012

I know I will need do some string manipulation to go from user input to a regular expression, but as an example I construct a regex like so:

^ABC.*2$

Unfortunately, this matches ABC-002 and ABC-012 .

Answer 1

You can do this replace on user input:

var re = new RegExp(input.replace(/\*/g, '-0*'), "gi");

This will convert ABC*2 to /ABC-0*2/gi regex and this will match ABC-002 but won't match ABC-012 .
