escape() [FF, IE 3]
Formats a string so that it conforms to URL encoding. Generally used for setting cookies (Chapter 12) and sending information to servers (Chapter 15 and Chapter 16).
Example:
var encoded_string = escape("a string safe for cookies");The variable encoded_string now holds a%20string%20safe%20for%20cookies because the escape function replaces spaces with %20. See "unescape() [FF, IE 3]" on page 448 for more information.
