Explode in javascript given a specific pattern

  • 772

Given the following string

var log = `added 20-11-19 10:02 - Lucho Jara : Un golpe de suerte espero despierto. Canción: Luis Jara - Un golpe de suerte
           added 21-12-20 11:52 - baby shark : Baby shark, doo doo doo doo doo doo`;;

The text with which I want to perform the explode is:added 20-11-19 10:02 - Lucho Jara :

The problem is that the date and time 20-11-19 10:02can vary but they will keep the format ( added **-**-** **:** -).

The name of the author after the date mentioned above can also vary (it is the same in length) - Lucho Jara :but the separators - :will always be kept.

Now, if we look at the description that follows, we realize that they could still contain the characters - :for which a traditional explode will not work for us.

Can wildcards be used? Any efficient way to do this?

  1. You could implement the js split method, something like:

    const str = 'tu texto';

    str.split("added").join(', ').split('-')

    and from there moving what needs to be separated

    Or with regular expressions:

        function miFuncion() {
      var str = "added 20-11-19 10:02 - Lucho Jara : Un golpe de suerte espero despierto. Canción: Luis Jara - Un golpe de suerte";
// Lo importante sigue
      var regex = /^added \d{1,2}-\d{2}-\d{2} \d{2}:\d{2} - .+ :/;
// 
      var resulta = str.match(regex);
      alert(resulta);
    }

    (This example returns "added 20-11-19 10:02 - Lucho Jara :")
