joshrhoades / dateHelpers.js

Last active August 29, 2015 14:07

Helper Date Functions, including determining leap year, and how many days in a month

	var isLeapYear = function(year) {
	return year % 4 === 0 && year % 100 !== 0 \|\| year % 400 === 0;
	}
	, getDaysInMonth = function(month, year) {
	return [31, isLeapYear(year) ? 29 : 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
	}
	;

joshrhoades / textContentPolyfill.js

Created February 7, 2014 23:41

IE8 polyfill/shim for supporting textContent (vs innerText) so that textContent is universally accessible. Can be embedded as a standalone script in a `[if lte IE 8]` embed.

	if (Object.defineProperty && Object.getOwnPropertyDescriptor && Object.getOwnPropertyDescriptor(Element.prototype, "textContent") && !Object.getOwnPropertyDescriptor(Element.prototype, "textContent").get) {
	(function() {
	var innerText = Object.getOwnPropertyDescriptor(Element.prototype, "innerText");
	Object.defineProperty(Element.prototype, "textContent",
	{
	get: function() {
	return innerText.get.call(this);
	},
	set: function(s) {
	return innerText.set.call(this, s);

joshrhoades / formatSeconds.js

Created January 27, 2014 21:30

Quick function to format passed in seconds and determine the weeks, days, hours, minutes, and seconds in that time. Returns an object of the values.

	var _formatCount = function(sec) {
	return {
	w: Math.floor(sec / 86400 / 7),//weeks
	d: Math.floor(sec / 86400 % 7),//days
	h: Math.floor(sec / 3600 % 24),//hours
	m: Math.floor(sec % 3600 / 60),//minutes
	s: Math.floor(sec % 3600 % 60)//seconds
	};
	};

joshrhoades / emptySRC.html

Created August 28, 2013 00:22

Set a blank img src for setting a background image since img.src can't be targeted directly. Disables the outline/placeholder of an img element that has no SRC value (which often is a side-effect of styling the parent element of the img with the background-image).

<img src="data:image/png;base64,R0lGODlhFAAUAIAAAP///wAAACH5BAEAAAAALAAAAAAUABQAAAIRhI+py+0Po5y02ouz3rz7rxUAOw==" />

joshrhoades / getFileExtension.js

Created August 8, 2013 00:31

	return theFile.split('.').pop();
	};
	getFileExtension('myfile.js');//returns 'js'

joshrhoades / stripFQDN.js

Last active December 20, 2015 18:39

	//returns '/assets/application-f348fb986aecf8d3b65e959e23f6a29f.css'

joshrhoades / noCallbackInstantExecute.js

Created June 21, 2013 19:53

Make a dynamically injected function always execute, without the delay of callbacks or the evil of `eval`. Amazingly simple solution that works like a charm. I needed this because I wanted to make dynamically precompiled templates instantly available (in PROD mode they are compiled into a JS file, and injected if a module on the page requires it…

	/*
	using jQuery AJAX as an example, though we do not leverage jQuery in our Production app.
	This technique can be used anywhere with injected data/functionality
	*/
	$.ajax({
	url: theTemplate.filePath,
	success: function(data) {
	/*
	Take the raw data of the file, insert it into a new function, and execute it.
	Bypasses need for callbacks, instantly executes it without delay, and does it without using `eval`.

joshrhoades / handlebars.getTemplate.js

Last active December 18, 2015 17:28

Function to expose precompiled handlebars as part of the handlebars object to make it easier to use HB in both DEV (runtime compile) and PROD (build/release-time compile)

	Handlebars.getTemplate = function(name) {
	if (Handlebars.templates === undefined \|\| Handlebars.templates[name] === undefined) {
	$.ajax({
	url : 'templatesfolder/' + name + '.handlebars',
	success : function(data) {
	if (Handlebars.templates === undefined) {
	Handlebars.templates = {};
	}
	Handlebars.templates[name] = Handlebars.compile(data);
	},

joshrhoades / logUncaught.js

Created May 9, 2013 00:28

JS global function to log all uncaught exceptions/errors, with optional method (stub) to fire and log to a server.

	var arrErrors = [];
	window.onerror = function(msg, fileURL, lineNum) {
	arrErrors.push({ msg: msg, file: fileURL, line: lineNum });
	};
	setInterval(function() {
	sendToServer(arrErrors);
	arrErrors = [];
	}, 5000);

	sendToServer(arrErrors) {

joshrhoades / prototypeShims.js

Common and useful Prototype Shims

	/**
	* SHIM to add `Date.now` functionality if it is not available, based off of EcmaScript 5.
