Javascript正则表达式每两组数字匹配一次>字母和数字？

Question

Trying to create a regex to:

• To get any number or multiple numbers first provided there's no spacing

• Then select a group of letters and numbers after any space. (Numbers optional)

This is currently working only when the groups of letters and numbers ends in a number

This is my regex - /(\b\d+\s+([a-z+d])+\d+\b)|(\b\d+\s+([a-z+d])+\b)/ig

This is my test string:

5 CF377A 
4
0 0CF377

At the moment its just currently selecting

0 0CF377

The result I need is

5 CF377A 
0 CF377

Link to my regular expression - Regex expression

Any help please ?

This captures the visible use-cases you've provided, but I'm not sure it passes all the requirements of your written description:

(^\d+ +[a-z0-9]+)
