The document discusses the Frost AJAX library designed for constrained browsers, emphasizing its cross-browser functionality and lightweight codebase. It offers features for basic AJAX requests and user extensibility while supporting a wide range of mobile browsers. The roadmap includes testing, community engagement, and enhancing the library based on user feedback.

Ajax library for constrained browsers

PavingWays

2. Motivation
●
Ajax works in many mobile browsers
●
JavaScript/DOM implementations vary
●
existing libraries don't work in many cases

3. Approach
●
cross-browser Ajax for mobile web apps
●
support weakest browser capable of Ajax
●
small codebase (core < 3k)
●
limited functionality in core
●
extensible by users
●
use only basic JavaScript (no prototyping)
●
fall-back mechanisms
●
task-oriented

4. What can it do?
●
browser-dependent output
●
debug output
●
basic Ajax requests
●
callbacks handling returned data
●
timeouts if offline
●
putting data somewhere
●
basic page manipulations

5. Supported Browsers
●
all ...
●
that know the XHR object
●
...or that know an ActiveX

6. How does it work?
●
testing -> browser capabilities DB
●
browser detection
●
capability-based output
●
...or universal version
●
server and client components (PHP, Rails)
●
write markup
●
load or include lib
●
execute f('name', [args])
