Today's programmatic venting is brought to you by Internet Explorer's implementation of the setTimeout() function under Javascript. What is setTimeout()? setTimeout() schedules an arbitrary function call for some point in future. This is useful when you have functions that do repetitive tasks some milliseconds apartment, but not constantly.

While most of the popular languages (Java, .NET, C++) have elaborate documents on the naming conventions to follow, I couldn't find any such good document for javascript. All I could find was bits and pieces here and there. This is the main reason why I am creating this page listing the javascript naming conventions I follow. This may not be complete but I shall try to make it as comprehensive as possible.

Code Conventions for the JavaScript Programming Language
This is a set of coding conventions and rules for use in JavaScript programming. It is inspired by the Sun document Code Conventions for the Java Programming Language . It is heavily modified of course because JavaScript is not Java . The long-term value of software to an organization is in direct proportion to the quality of the codebase. Over its lifetime, a program will be handled by many pairs of hands and eyes. If a program is able to clearly communicate its structure and characteristics, it is less likely that it will break when modified in the never-too-distant future.

Operation Cleanout - Unobtrusive Javascript
Web development in the last year(s) has undergone a change, we stopped mixing presentation with structure, and thus made it easier to rebrand and change the layout throughout the site simply by changing the style sheet. Further separation is possible by not using any inline styles and classes, but inheritance and contextual selectors. HTML : <table border="0" cellpadding="0" width="100%" cellspacing="5"><tr><td><font face="Arial" size="-2">Lorem Ipsum</font></td></tr></table> became and finally The same evolution can and must happen for Javascript.This section defines a set of objects and interfaces for accessing and manipulating document objects. The functionality specified in this section (the Core functionality) is sufficient to allow software developers and web script authors to access and manipulate parsed HTML and XML content inside conforming products. The DOM Core API also allows creation and population of a Document object using only DOM API calls; loading a Document and saving it persistently is left to the product that implements the DOM API. 1.1.1. The DOM Structure Model The DOM presents documents as a hierarchy of Node objects that also implement other, more specialized interfaces.

Esta es una pequeña recopilación de funciones Javascript que deberíamos tener siempre presente en nuestra mente a la hora de desarrollar una aplicación Javascript . Algunas de estas funciones son muy comunes en otros lenguajes , pero por un motivo o por otro en Javascript no estan tan popularizadas. Trim Trim es posiblemente una de las funciones más útiles que podemos encontrar a la hora de trabajar con cadena pero es una función que echamos de menos en Javascript, simplemente se encarga de eliminar los espacios en blanco del principio y fin de una cadena y en casi cualquier lenguaje de programación hay una función parecida que cumple con esta función, lástima que Javascript no la posee pero con la ayuda de Prototype nos podremos crear nuestra función Trim. Para la creación de esta función nos vamos a aprovechar de la posibilidad que nos da Prototype de modificar un objeto añadiendole atributos o métodos nuevos, esto incluye los objetos nativos de Javascript.

Esta es una lista de las 10 librerías más útiles que he encontrado y que utilizo a menudo, es una manera sencilla de utilizar la últimas tecnologias con un ahorro de tiempo considerable y resultados excelentes. Estas librerías se basan en lenguajes como javascript,php,ajax,css… 1) Moo.fx – Su principal cualidad es que es muy ligera,más bien la podríamos definir como una diminuta libreria de efectos javascript escrita con prototype.js . Es fácil de usar,rápida y nos ofrece controles para modificar atributos como Height, Width, y Opacity con un gran rendimiento.Esta tambien optimizada para que escribas el menor código posible.
