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

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.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.
	//
	// The function to notice is:
	// applyTemplate(data/{}, target/DOMNode, keepPreviousTemplate/boolean)
	//
	var templateCache = null;
	$.template = Class.extend({

	this.getput = this.putget;
	},
	contains: function(key) {
	return this.ready[key] !== undefined;

Add Timeout to Deferred

	define(["jquery"],
	function($) {
	var addTimeout = $.addTimeoutToDeferred = function(promise, timeout) {
	if (promise.isResolved() \|\| promise.isRejected())
	return promise;
	var withTimeout = $.Deferred();

	setTimeout(function() {withTimeout.reject();}, maxWait);
	return withTimeout.promise();
	}

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.deferredPipeline.js

Created October 21, 2011 13:33

$.Deferred Pipeline

	define(["jquery"], function($) {
	//
	// Given a list of functions that return a promise or an object,
	// Set them up to execute them in order using those promises.
	// and returns a promise that resolves after the last promises returned by the function pipeline resolves.
	//
	var deferredPipeline = $.deferredPipeline = function(/* [function, ]*/) {
	//reversed pipeline
	var toPipe = Array.prototype.slice.call(arguments).reverse();
	if (toPipe.length == 0) {
