donabrams / jquery.deferredStack.js
Created October 21, 2011 13:34
Deferred Stack with functions all taking the same arguments (interceptor stack really).
define(["jquery/1.5.1/jquery"], function($) {
//
// This function executes a list of promise returning functions all given the same args
// If you specify a scope, the list may contain string names instead of function references.
// It returns a Promise
//
var executeDeferredStack = $.executeDeferredStack = function(functionStack, args, scope) {
var dfd = $.Deferred();
var lastFunc = function() {
dfd.resolve(arguments);

donabrams / jquery.templater.js
Created October 21, 2011 14:04
Deferred template class with optional caching and url fetching. Uses jqote2 (but easily changed).
define(["jquery", "jquery.jqote2", "jquery.deferredPipeline", "jquery.cache"],
function($, jqote2, deferredPipeline, cache) {
//
// This is a wrapper around the jqote2 template library.

// applyTemplate(data/{}, target/DOMNode, keepPreviousTemplate/boolean)
//
var templateCache = null;

donabrams / jquery.statesfulWidget.js
Created October 21, 2011 15:31
Deferred Widget solution with templates, states, and stores. Not really complete at this time.
define(["jquery/1.5.1/jquery", "Class", "jquery.store", "jquery.executeDeferredStack", "jquery.templater"],
function($, Class, Store, executeDeferredStack, Templater) {
//TODO: somehow let widget state be exposed without depending on widget internals
//
// This is a widget state implementation.
//
// args:
// Recommended:
// templateName/String - should map to a widget.templates[templateName]
// actions/{} - map of action String to either a String or function()->String.

donabrams / jquery.enumeratedFunction.js
Created October 26, 2011 17:30
Enumerated Function
var exampleFunction = function(a, b, c) {
$(a).append("<p>" + b + "->" + c + "</p>");
};
exampleFunction("#a", "example", 1);
//
// This function goes through each entry in the array values
// and if it is an array, Calls func once per value in the array.
//
// The real use of this function is to easily allow functions that normally take
// single values to be expanded without any real work. See Ruleset.addValidator
