Inverse regex javascript

Question

I'm trying to remove everything in a string that does not match 'standard' characters. Heres what I have so far:

var result = myString.replace(/^(?![A-Za-z0-9]+)/g, '');

Which does not work. Can someone point to me what I'm not doing right?

Answer 1

I think you mean this:

var result = myString.replace(/[^a-z0-9]/gi,'');
