Add space in the string before and after certain characters

Question

I want to add space in the string before and after certain characters.

var x = "asdasdasdasd+adasdasdasd/asdasdasdasd*asdasdasd-asdasdasd:asdasdasdadasdasd?";

I want to add space before and after

var separators = ['+', '-', '(', ')', '*', '/', ':', '?'];

So the output will be like

asdasdasdasd + adasdasdasd / asdasdasdasd * asdasdasd - as ( dasd ) asd : asdasdasdadasdasd ?

Answer 1

You can use a Regex for that.

for (var i = 0; i < separators.length; i++) { 
      var rg = new RegExp("\\" + separators[i], "g"); 
      x = x.replace(rg, " " + separators[i] + " "); 
}

Answer 2

You may use something like that:

var str = x.replace(new RegExp('\\' + separators.join('|\\'), 'g'), ' $& ')
