Answer 1

By adding our .cleanup() method to the String object itself, you can then cleanup any string in Javascript simply by calling a local method, like this:

# Attaching our method to the String Object
String.prototype.cleanup = function() {
   return this.toLowerCase().replace(/[^a-zA-Z0-9]+/g, "-");
}

# Using our new .cleanup() method
var clean = "Hello World".cleanup(); // hello-world

Answer 2

Or this if you wanted to put dashes in the place of other chars:

string.replace(/[^a-zA-Z0-9]/g,'-');

Answer 3

Assuming the string is kept in a string called BizName:

BizName.replace(/[^a-zA-Z0-9]/g, '-');

BizName should now only involve the characters requested.
