Internet Explorer 5.5 introduced four new methods to encode strings to URIs as well as to decode URIs to strings. The first method, encodeURI(string), encodes a string as a full URI. Let's take an example. The following line:

encodeURI("My phone # is 123-456-7890")); 

should generate the following string:

My%20phone%20#%20is%20123-456-7890

The other three methods are encodeURIComponent(), decodeURI(), and decodeURIComponent(). Read all about them in Column 59, IE 5.5: Formatting, URIs, and Stack Operations.
