How do I split a string with multiple separators in javascript?

Question

How do I split a string with multiple separators in JavaScript? I\'m trying to split on both commas and spaces but, AFAIK, JS\'s split function only supports one separator.

Answer 1

An easy way to do this is to process each character of the string with each delimiter and build an array of the splits:

splix = function ()
{
  u = [].slice.call(arguments); v = u.slice(1); u = u[0]; w = [u]; x = 0;

  for (i = 0; i < u.length; ++i)
  {
    for (j = 0; j < v.length; ++j)
    {
      if (u.slice(i, i + v[j].length) == v[j])
      {
        y = w[x].split(v[j]); w[x] = y[0]; w[++x] = y[1];
      };
    };
  };
  
  return w;
};

console.logg = function ()
{
  document.body.innerHTML += "
" + [].slice.call(arguments).join();
}

splix = function() {
  u = [].slice.call(arguments);
  v = u.slice(1);
  u = u[0];
  w = [u];
  x = 0;
  console.logg("Processing: " + JSON.stringify(w) + "");

  for (i = 0; i < u.length; ++i) {
    for (j = 0; j < v.length; ++j) {
      console.logg("Processing: [\x22" + u.slice(i, i + v[j].length) + "\x22, \x22" + v[j] + "\x22]");
      if (u.slice(i, i + v[j].length) == v[j]) {
        y = w[x].split(v[j]);
        w[x] = y[0];
        w[++x] = y[1];
        console.logg("Currently processed: " + JSON.stringify(w) + "\n");
      };
    };
  };

  console.logg("Return: " + JSON.stringify(w) + "");
};

setTimeout(function() {
  console.clear();
  splix("1.23--4", ".", "--");
}, 250);

@import url("http://fonts.googleapis.com/css?family=Roboto");

body {font: 20px Roboto;}

Usage: splix(string, delimiters...)

Example: splix("1.23--4", ".", "--")

Returns: ["1", "23", "4"]
