Replace multiple strings of unknown content, length

Question

I am trying to replace multiple delimiters within a single string with a break tag, but the delimiters are not always the exact same or of the same length. The delimiters do follow this pattern when within the string: #[some number];#

For example, I want

49;#Simpson, Homer;#45;#Simpson, Bart

to become

Simpson, Homer
Simpson, Bart

And I want

49;#Simpson, Homer;#45;#Simpson, Bart;#101;#Simpson, Lisa

to become

Simpson, Homer
Simpson, Bart
Simpson, Lisa

I was using the following to remove the first [number];# from the string, but I'm not sure how to replace the rest.

peopleString = peopleString.substring(peopleString.indexOf(";#") + 2);

Thanks!

The numbers are the ID of the person, but I don't care about them for this example. They can be be any number of digits 1, 2, 3, etc. — user31619

Here's a solution that uses regex after your initial replacement of the first [number];#,

Some more info about regular expressions: https://stackoverflow.com/tags/regex/info

var replacement = '<br>';
var doReplace = function(str) {
  str = str.substring(str.indexOf(";#") + 2);
  return str.replace(/;#[0-9]+;#/g, replacement);
}

document.write(doReplace('49;#Simpson, Homer;#45;#Simpson, Bart'));
document.write('<br>---<br>')
document.write(doReplace('49;#Simpson, Homer;#45;#Simpson, Bart;#101;#Simpson, Lisa'));

This is an excellent candidate for the Regular Expression replace function:

https://developer.mozilla.org/en/docs/Web/JavaScript/Guide/Regular_Expressions

Look into using the replace function and the Global flag to replace all instances of your delimiter

You could use Regular Expressions to do that.

you could try with sample

var string = '49;#Simpson, Homer;#45;#Simpson, Bart;#101;#Simpson, Lisa'
string.replace('/;*#*\d+;#*/g','');
console.log('result',string);
