使用Javascript通过数字或alpha字符将字符串拆分为块 [英] Splitting a string into chunks by numeric or alpha char with Javascript
问题描述
所以我有这个:
var str = A123B234C456;
我需要将其拆分为逗号分隔的块以返回如下内容:
I need to split it into comma separated chunks to return something like this:
A,123,B,234,c,456
我认为正则表达式最适合这个,但我一直卡住,基本上我试图做一个字符串替换,但你不能在第二个参数中使用正则表达式
I thought regex would be best for this but i keep getting stuck, essentially I tried to do a string replace but you cannot use regex in the second argument
我希望保持简单和干净并做这样的事情,但它不起作用:
I would love to keep it simple and clean and do something like this but it does not work:
str = str.replace(/[\d]+/, ","+/[\d]+/);
但在现实世界中太简单了。
but in the real world that would be too simple.
有什么想法?提前致谢!
Any thoughts? Thanks in advance!
推荐答案
匹配角色然后加入它们可能更明智:
It may be more sensible to match the characters and then join them:
str = str.match(/(\d+|[^\d]+)/g).join(',');
但是在定义字符串时不要省略引号:
But don't omit the quotes when you define the string:
var str = 'A123B234C456';
