拆分多个分隔符的字符串

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?

Answer 1

Try this.

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

Answer 2

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.

Answer 3

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
