Question

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

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

9:30 pm
The user did action A.

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

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

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

30 pm
    The user did action A.

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

Thanks!

Answer 1

Use a lookahead:

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