Using regular expression in replace method in javascript [duplicate]

Question

I have a string like %B~7566952, and I want a regular expression that can be applied to replace it to get B7566952, so a regular expression that takes non-alphanumeric characters and deletes them.

The first paragraph of stackoverflow.com/a/9364527/2102532 does what you need, this should be closed as a duplicate. — meskobalazs

var str = "%B~7566952";
document.write(str.replace(/[^a-zA-Z0-9]/g, ""));

str.replace(/\W/g, '') is equivalent (well nearly, as the underscore character is in W but not in your expression)
