Best way to remove these chars from javascript string

Question

I'm looking for a way to remove these characters from a string in javascript (and spaces).

?[]/\=<>:;,'\"&$#*()|~`!{}

I am unsure how to construct this:

"mystring is - ?[] hello ".replace(regex, "");

Some elements need escaping, some do not?

Inside a character class [], most don't need escaping:

var pattern = /[?\[\]/\\=<>:;,'"&$#*()|~`!{}]/g; "mystring is - ?[] hello ".replace(pattern, "");

The g flag is added for global replacement.

alert("mystring is -<> ;:,'\"&%^=!{} ?[] hello ".replace(pattern, "")); // Prints: mystring is - %^ hello
