JavaScript正则表达式拆分数字和字母

Question

I need regex pattern to split a string into numbers and letters. Ie .1abc2.5efg3mno should be split into [".1","abc","2.5","efg","3","mno"] .

The current regex I tried is:

var str = ".1abc2.5efg3mno";
regexStr= str.match(/[a-zA-Z]+|[0-9]+(?:\.[0-9]+|)/g);

Output obtained is:

["1","abc","2.5","efg","3","mno"]

The number .1 is taken as 1 whereas I need it as .1 .

Answer 1

If it's a matter of separating letters from non-letters, then the regex can be made quite simple:

 var str = ".1abc2.5efg3mno"; var regexStr = str.match(/[az]+|[^az]+/gi); console.log(regexStr); 

Ie match a group of letters or a group of non-letters.

Answer 2

 var z = ".1abc2.5efg3mno".match(/[\\d\\.]+|\\D+/g); console.log(z);
