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

Lets keep it simple: (add a "[ ]+" to your RegEx means "1 or more")

This means "+" and "{1,}" are the same.

var words = text.split(/[ .:;?!~,`"&|()<>{}\[\]\r\n/\\]+/); // note ' and - are kept

Answer 2

Perhaps you should do some sort of string replace to turn one separator into the other separator so you then only have one separator to deal with in your split.

Answer 3

a = "a=b,c:d"

array = ['=',',',':'];

for(i=0; i< array.length; i++){ a= a.split(array[i]).join(); }

this will return the string without a special charecter.

Answer 4

Hi for example if you have split and replace in String 07:05:45PM

var hour = time.replace("PM", "").split(":");

Result

[ '07', '05', '45' ]

Answer 5

For fun, I solved this with reduce and filter. In real life I would probably use Aarons answere here. Nevertheless I think my version isn't totally unreadable or inefficient:

[' ','_','-','.',',',':','@'].reduce(
(segs, sep) => segs.reduce(
(out, seg) => out.concat(seg.split(sep)), []), 
['E-mail Address: user@domain.com, Phone Number: +1-800-555-0011']
).filter(x => x)

Or as a function:

function msplit(str, seps) {
  return seps.reduce((segs, sep) => segs.reduce(
    (out, seg) => out.concat(seg.split(sep)), []
  ), [str]).filter(x => x);
}

This will output:

['E','mail','Address','user','domain','com','0','Phone','Number','+1','800','555','0011']

Without the filter at the end you would get empty strings in the array where two different separators are next to each other.

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 += "<br>" + [].slice.call(arguments).join();
}

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

  for (i = 0; i < u.length; ++i) {
    for (j = 0; j < v.length; ++j) {
      console.logg("Processing: <code>[\x22" + u.slice(i, i + v[j].length) + "\x22, \x22" + v[j] + "\x22]</code>");
      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: <code>" + JSON.stringify(w) + "</code>");
};

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"]
