Debugging JavaScript This document is intended to help developers writing JavaScript code in Mozilla, mainly for Mozilla itself, but it may also be useful for web developers. It should give pointers to tools, aids and tricks which make debugging your code easier. Web Console This is the first place to go when you're debugging a web page; open the Web console using the Web Console option in the Web Developer menu. This shows any JavaScript errors in your app, as well as any logging calls from the console API. Browser Console The Browser Console lets you see all JavaScript errors and logging in the browser, including from Firefox code. You can also start the Browser Console when you launch Firefox, by launching Firefox from the command line and passing --jsconsole as a flag: /path/to/firefox --jsconsole Log to the Browser Console using the standard console API after importing Console.jsm: let console = (Cu.import(" {})).console; console.log("Hello from Firefox code");
Responsive Multi-Level Menu A responsive multi-level menu that shows its submenus in their own context, allowing for a space-saving presentation and usage. View demo Download source Today we want to share an experimental drop-down menu with you. The main idea is to save space for menus that have a lot of content and sub-levels. Each sub-level in this menu will be shown in its own context, making the “parent” level disappear. This is done with subtle animations that are defined in separate animation classes. Please note: this only works as intended in browsers that support the respective CSS properties. The structure of the menu contains an unordered list that can have an arbitrary number of sub-lists: Animations are defined in animation classes: And the plugin is called as following: We hope you like this little experiment and find it inspiring!
Tutorial: Debugging This tutorial introduces you to using Google Chrome's built-in Developer Tools to interactively debug an extension. To follow this tutorial, you need the Hello World extension that was featured in Getting Started. In this section, you'll load the extension and take a look at its information in the Extensions page. Load the Hello World extension if it isn't already running. If the extension is running, you'll see the Hello World icon to the right of your browser's address bar. If the Hello World extension isn't already running, find the extension files and load them. As long as your browser is in Developer mode, it's easy to inspect popups. Go to the Extensions page ( and make sure Developer mode is still enabled. The popup remains open as long as the Developer Tools window does. In this section, you'll follow the execution of the popup page as it adds images to itself. Use the buttons next to the play/pause button to step over, into, and out of function calls.
Responsive Web Design: Using Fonts Responsively Typography is one of the most important aspects of responsive web design, and optimizing your fonts for mobile devices is an absolute necessity if you want your content to be palatable across all screen sizes. Fortunately, the process of building flexible fonts is not very difficult. When we talk about flexibility (which is the guiding principle in this case), we cannot overlook the specified size of the font we’ve chosen to adapt for our responsive website. We may use different metrics for this purpose, including pixels, ems, rems, or percentages. Choosing the right metric is critical for designing a malleable, responsive interface. In this continuation on responsive web design, I’ll explain how to manage dynamic fonts responsively, and I’ll analyze all of the aforementioned metrics, comparing the strength and weaknesses of each choice. Pixels For a long time, pixels have been the unit preferred of web designer due to its inherent precision and accuracy. Ems Percentages Rems Conclusions
JavaScript JavaScript (JS) es un lenguaje de programación ligero, interpretado, o compilado justo-a-tiempo (just-in-time) con funciones de primera clase. Si bien es más conocido como un lenguaje de scripting (secuencias de comandos) para páginas web, y es usado en muchos entornos fuera del navegador, tal como Node.js, Apache CouchDB y Adobe Acrobat JavaScript es un lenguaje de programación basada en prototipos, multiparadigma, de un solo hilo, dinámico, con soporte para programación orientada a objetos, imperativa y declarativa (por ejemplo programación funcional). Lee más en acerca de JavaScript. Esta sección está dedicada al lenguaje JavaScript en sí, y no a las partes que son específicas de las páginas web u otros entornos host. Para información acerca de APIs específicas para páginas Web, consulta APIs Web y DOM. El estándar para JavaScript es ECMAScript (ECMA-262) y la especificación de la API para la Internacionalización de ECMAScript (ECMA-402). Empieza aquí Tutoriales JavaScript asíncrono
