使用 JavaScript 按数字或字母字符将字符串拆分为块 [英] Splitting a string into chunks by numeric or alpha character with JavaScript

问题描述

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 最适合这种情况，但我一直被卡住.本质上，我尝试进行字符串替换，但您不能在第二个参数中使用正则表达式.

I thought a regular expression would be best for this, but I keep getting stuck. Essentially, I tried to do a string replace, but you cannot use a regular expression in the second argument.

我很想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]+/);

但在现实世界中这太简单了.

But in the real world that would be too simple.

有可能吗?

推荐答案

匹配字符然后加入可能更明智:

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';
