Keypress: A Javascript library for capturing input The first thing to do is include the JavaScript file in your page. Once you've got that loaded in, you'll want to start by instantiating a listener: var listener = new window.keypress.Listener(); Once you've done that you can register combos with that listener you've created. The simplest way to do that is using the simple_combo API. It takes a space dilineated string or an array of strings of key names that describe your combo. listener.simple_combo("shift s", function() { console.log("You pressed shift and s"); }); listener.counting_combo("tab space", function(e, count) { console.log("You've pressed this " + count + " times."); }); listener.sequence_combo("up up down down left right left right b a enter", function() { lives = 30; }, true); If you only want to use Keypress for some very simple keyboard shortcuts, that's all you need to know! listener.unregister_combo("shift s"); listener.unregister_many(my_registered_combos); listener.reset();
Codeblock.js by Filepicker.io Why? Humans learn better when they can play with what they're working with, when they can poke at it and understand what happens to B when you change A. The browser provides a wonderful place where examples can be interactive, and yet most documentation for javascript APIs doesn't make use of these capabilities. Codeblock.js turns example code into editable, runnable code blocks that visitors can poke at and play with to better understand your API. For example, try playing with the parameters in the example below: Output from the example appears here run Using Codeblock.js Codeblock.js is a jQuery plugin that uses the Ace code editor, and therefore requires including both jQuery and Ace. Once the scripts are imported, you can use the $.codeblock call to transform any piece of text into an editable, runnable code sample. The codeblock.js api is very similar to the api of jQuery UI widgets, so if you are familiar with those the syntax should feel natural. Instantiation Methods Events
