Curso de jQuery (2): Selectores, Primera Parte Por un selector entendemos en jQuery lo mismo que en CSS: una forma de permitirnos elegir un elemento (o varios) entre todos los que tenemos en nuestro documento HTML. ¿Para qué? Para luego poder aplicar sobre los elementos seleccionados diversas funciones. Es decir, jQuery utiliza el poder de los selectores para acceder de una manera rápida y sencilla a un elemento o grupo de elementos del DOM (Document Object Model) y luego poder aplicar sobre los mismos cualquier tipo de instrucción, evento, animación, etc…. Pero vamos a empezar desde el principio. Antes de nada es importante saber que el DOM (Document Object Model, el esqueleto de nuestra página web) utiliza una estructura de árbol para definir las relaciones entre sus elementos, en la que tenemos padres, hijos, etc… Por ejemplo: $(‘selector’) No importa qué tipo de selector usemos en jQuery: siempre comenzaremos con $(). Selectores CSS Selectores propios de jQuery Vamos a distinguir entre ellos: Otros capítulos del curso

browserify D3.js - Data-Driven Documents Dan Grossman | A date range picker for Twitter Bootstrap While developing Improvely, having all the components of Twitter Bootstrap at hand pre-styled was a great time saver. I was in need of a dropdown menu to choose date ranges for reports, and wanted something that would match the existing dropdown and button styles of Bootstrap: thus came about this date range picker component. Download it at GitHub. For basic use cases like collecting event or reservation dates, you can attach it to a text input to pop up two clickable calendars to choose dates from. For more advanced use cases, you can attach a date range picker to any element, pre-define your own date ranges for the user to choose from, and set a custom callback function to receive the chosen dates. In 2013, the Date Range Picker was updated with many new options, including a time picker, min/max dates and max range, localization of all buttons/labels, dropdowns to jump between months/years and more. Usage: The examples below show how to use the (optional) options and callback parameters.

arbor.js 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. 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! If you want to use some of the more advanced features of Keypress, you can use the register_combo API and supply an object with any number of options described below. listener.unregister_combo("shift s"); listener.unregister_many(my_registered_combos); listener.reset();
