Question

I just asked a question about Regex, and received a great answer: JavaScript Split without losing character

Now, I have another question.

My current Regex looks like this:

var split = text.split(/(?=\w*\d*\d:\d\d)/);

Basically, I’m trying to split using the timestamps (eg – 9:30 or 10:30, the difference between them is the extra digit in the latter). How do I go about this?

Currently, if I have these two:

9:30 pm
The user did action A.

10:30 pm
Welcome, user John Doe.

The splits are :

9:30 pm
The user did action A.
----
1
----
0:30 pm
Welcome, user John Doe.

How do I add an optional check for the first character in the timestamp?

Thanks!

Answer 1

See my answer to your other question, I fixed this problem in the regex by adding a word boundary:

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

Updated it with \s* to strip out any unnecessary whitespace (but not the line breaks) too. Result:

["9:30 pm    
The user did action A.", "10:30 pm  
Welcome, user John Doe.", "11:30 am
Messaged user John Doe"]
