使用正则表达式拆分 javascript 字符串以将数字与其他字符分开

Question

so for example:

"10.cm" ...becomes... [10,".cm"] or ["10",".cm"] , either will do as I can work with a string once it's split up.

i tried

"10.cm".split(/[0-9]/|/[abc]/)

but it seems that i don't have such a great understanding of using regexp's

thanks

Answer 1

You may tokenize the string into digits and non-digits with /\\d+|\\D+/g regex:

 var s = "10.cm"; console.log(s.match(/\\d+|\\D+/g)); 

Details :

• \\d+ - matches 1 or more digits
• | - or
• \\D+ - matches 1 or more characters other than digits.

Answer 2

/\W/ Matches any non-word character. This includes spaces and punctuation, but not underscores. In this solution can be used /\W/ with split and join methods. You can separate numbers from other characters.

let s = "10.cm";
console.log(s.split(/\W/).join(" "));

output = 10 cm
