url parsing "plugin" in response to this: https://github.com/websanova/js-url

nickjacob / switchy.js

Created November 6, 2012 07:50

Javascript is the perfect language for dispatch tables

	/* Why would you ever need a switch statement in javascript? */

	var switchy = {
	1: function(x){ return x*x; },
	pizza: function(x){ return xxX }
	};

	var bar = switchy[foo](10);

	// what if you could extend it with regex?

nickjacob / api_wrapper.rb

Last active December 11, 2015 04:28

I know this has been done before, but here's my metaprogramming solution to wrapping a RESTful API.

	###
	# API Client for "MyApi"
	###
	require 'httparty'
	require 'yaml'

	module MyApi

	class Config
	attr_accessor :base_url, :page_size, :key

	function __deep(obj, prop) {
	var parts = prop.split('.'), i = -1, l = parts.length;
	while(++i < l) {

just an idea I wanted to play with; for a searching app, shouldn't the user be able to refresh and get the same parameters in the field/query?

	inputRe = /input\|select\|textarea/i # some browsers do uppercase tagNames; also faster than 3 strcmp

	cache = {}
	elByName = (el) ->
	cache[el.name] ?= document.getElementsByName el.name

	document.addEventListener 'load', (e) ->
	document.addEventListener 'change', (e) ->
	target = e.target

nickjacob / µTpl.coffee

Last active December 14, 2015 06:39

impl of my picotemplate in coffeescript to see what it'd be like

	__deep = (obj, prop) ->
	for p in prop.split '.'
	if not (p in obj and obj = obj[p])
	return undefined
	obj() if typeof obj is 'function' else obj

	getEscape = (tpl) ->
	qq = "\'" if '"' in tpl else "\""
	(str) -> qq + str + qq

nickjacob / script.rb

Created March 25, 2013 21:41

I've been writing a lot of ruby scripts that I want to make more usable/modular, realized I need a common template/api for these things

nickjacob / appending.js

Last active December 16, 2015 12:59

overview of different ways to append to the DOM

	// inefficient because you call append multiple times
	// this causes a reflow on each call (https://developer.mozilla.org/en-US/docs/Notes_on_HTML_Reflow)
	$('#my-el').append('<div>hi</div>').append('<div>two</div>').append('<div>three</div>');

	// you could just make 1 string of HTML
	var to_append = '<div>hi</div><div>two</div><div>three</div>';
	$('#my-el').append(to_append);

	// or you can use documentFragment;
	// documentFragment is a container for DOM elements that, when you eventually attach it to the DOM, disappears so
