I need regex pattern to split a string into numbers and letters. I.e. .1abc2.5efg3mno should be split into [".1","abc","2.5","efg","3","mno"].
我需要正则表达式模式将字符串拆分为数字和字母。即.1abc2.5efg3mno应分为[“。1”,“abc”,“2.5”,“efg”,“3”,“mno”]。
The current regex I tried is:
我试过的当前正则表达式是:
var str = ".1abc2.5efg3mno";
regexStr= str.match(/[a-zA-Z]+|[0-9]+(?:\.[0-9]+|)/g);
Output obtained is:
获得的输出是:
["1","abc","2.5","efg","3","mno"]
The number .1 is taken as 1 whereas I need it as .1.
数字.1被视为1而我需要它为.1。

If it's a matter of separating letters from non-letters, then the regex can be made quite simple:
如果是将字母与非字母分开,则可以使正则表达式变得非常简单:
var str = ".1abc2.5efg3mno";
var regexStr = str.match(/[a-z]+|[^a-z]+/gi);
console.log(regexStr);I.e. match a group of letters or a group of non-letters.
即匹配一组字母或一组非字母。
