Invalid regular expression: /(/: Unterminated group

Question

I want to create a function that removes all unwanted characters from a text. That´s waht I came up with, but it doesn´t work:

var invalid = "^°\"§%()[]{}=\\?´`'#<>|,;.:-+_";

for (var n = 0; n < invalid.length; n++) 
{
   var r = new RegExp(invalid[n],"g");
   toCheck.replace(r,"");
} 

Answer 1

You don't need to loop through invalid characters. Just use regex like this:

var invalid = /[°"§%()\[\]{}=\\?´`'#<>|,;.:+_-]+/g;
var repl = toCheck.replace(invalid, "");
