JavaScript拆分而不会丢失字符 [英] JavaScript Split without losing character

问题描述

我想使用JavaScript拆分某些文本。文字如下：

I want to split certain text using JavaScript. The text looks like:

9:30 pm
The user did action A.

10:30 pm
Welcome, user John Doe.

11:30 am
Messaged user John Doe

现在，我想把字符串拆分成事件。 ie：

Now, I want to split the string into events. i.e.:

9:30 pm
The user did action A.

将是一个事件。我正在使用RegEx：

would be one event. I'm using RegEx for this:

var split = journals.split(/\d*\d:/);

事实上，前两个字符正在丢失。拆分如下所示：

Thing is, the first two characters are getting lost. The split appears like this:

30 pm
    The user did action A.

如何分割以使分割保持前两个/三个字符（即 9：或 10：）等等？

How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc?

谢谢！

推荐答案

使用前瞻：

var split = journals.split(/(?=\b\d+:)/);
