Question

Get the characters from a JavaScript string, but make sure to exclude

There is a text string that I need to work with:

TEST:ABCDEGF:18:32

This text includes letters and numbers, but I want to extract all of them excluding the : character.

Previously, I was using the following code successfully:

lines.split(":");

However, I now have a new requirement where I also need to extract the time in full form like 18:32, which means simply using split won't cut it because it only gives me until 18.

So, how can I modify my approach in order to extract the time as well?

For example:

ABCDED:ERERE:18:32

Desired output:

 temp.fields[0] = ABCDED
 temp.fields[1] = ERERE
 temp.fields[2] = 18:32

Answer №1

If the time is consistently located at the end, you can utilize this method.

function manipulateString(str) {
  var arr = str.split(':');
  var timeSection = arr.splice(-2).join(':'); // remove last 2 elements from array and join them
  arr.push(timeSection);
  return arr;
}

console.log(manipulateString('TEST:ABCDEGF:18:32'));

function manipulateString(str) {
  var arr = str.split(':');
  var timeSection = arr.splice(-2).join(':'); // remove last 2 elements from array and join them
  arr.push(timeSection);
  return arr;
}

console.log(manipulateString('TEST:ABCDEGF:18:32'));

After investigating the issue thoroughly, I was able to find a solution:

let remainder = elements.splice(3).join(':');

I came across this helpful tip on:

Splitting strings with limits, capturing the remaining string

This workaround is exactly what I needed to achieve my desired outcome.

Give this a shot

let str = `ANOTHER EXAMPLE:XYZ123AB:MNO:TUVW:xx:34:EFG:45:56:PPP`;;

let n = str.replace(/(\d\d\:\d\d)|\:/g,"$1 ").replace(/ +/g,' ').split(' ');

console.log(n);

Regexp explanation: "\d\d:\d\d" identifies the time in the first group, ":" matches a colon, then only the first group followed by a space "$1 " is output (colons are omitted and unmatched text remains unchanged), and finally (in the 2nd replace) double spaces are changed to single spaces before being split into an array.

To adjust the delimiter (:) in all instances except when it appears between numbers, you can utilize the replace method. Here is an example of how this can be achieved:

const data = "ABCDED:ERERE:18:32";

const arr = data.replace(/:/g, function(match, pos, str){
  const before = str.substring(pos - 2, pos);
  const after = str.substring(pos + 1, pos + 3);

  if(!isNaN(before) && !isNaN(after)){
    return match;
  }else {
    return "|";
  }
}).split("|");

console.log(arr);

console.log(arr);

After coming across a comment stating that time always appears at the end, I decided to provide a simpler second answer in text format.

temp.fields = [...s.slice(0,-6).split(':'), s.slice(-5)]

let s="ABCDED:ERERE:18:32"

let fields =  [...s.slice(0,-6).split(':'), s.slice(-5)]; 

console.log(fields);
