Question

In JavaScript, is there any class equivalent for

• NSURL class in iOS SDK or
• URL class in Java?

With such class, I want to:

• normalize URL,
• compose a URL from scheme, host, path components, etc…, and
• decompose a URL into its elements.

Answer 1

James Padolsey had tackled this problem.

In a nutshell, you can create an anchor element using document.createElement(), and several of its native properties are then easily accessible, such as protocol, port, and hostname.
