Split string with multiple separators

Question

I have a string where I need to separate it by +-*/ and put it into array.

I've tried this code that I also found here, but it doesn't seem to be working. It gives me the error "Invalid regular expression: /+|-|*|//: Nothing to repeat."

var separators = ['+', '-', '*', '/'];
var numbers = x.split(new RegExp(separators.join('|'), ''));

Any advice on how should I do this?

the problem is that some of those characters have special meanings in a RegExp ... so you need to escape them with more \\ than you think — Jaromanda X

+ and * have special significance in regex. Try string.split(/[\+-\*\/]/g) — Rajesh Dixit

@Harsha No. There's no special characters other than the four — AyakoS

Try this.

var str = "i-have_six*apples+doyou/know.doe";
console.log(str.split(/[.\*+-/_]/));

Here is your answer,

x = "This+is*test/the*theunder-Yes";
var separators = ['\\\+', '-', '\\*', '/'];

var numbers = x.split(new RegExp(separators.join('|'),'g'));
console.log(numbers);

It is because, your +,* are regex related wild card characters. You can't use as is.

use regex split

    var tempvar = (X).split(/[+-/*]+/);

This should return as array split. eg : X = 1+2-3/4

alert(x) would return as 

    1,2,3,4
