Web Animation using JavaScript: Develop & Design
We’ve come a long way since the days of flashing banner ads and scrolling news tickers. Today, the stunning motion design of iOS and Android dramatically improves a user’s experience — instead of detracting from it. The best sites and apps of today leverage animation to improve the feel and intuitiveness of their interfaces. Sites without animation are starting to feel antiquated.This book provides you with a technical foundation to implement animation in a way that’s both visually stunning and programmatically maintainable. Throughout, we consider the balance between enriching a page with motion design while avoiding unnecessary flourishesReaders will learn how to design loading sequences that ensure users stay fully engaged instead of tuning out, how to leverage simple physics principles to make apps respond naturally to users’ input (just like motion behaves in the real world), how to exploit CSS transforms to create rich depth in animations, and how to fully leverage JavaScript animation libraries like Velocity.js to streamline animation programming. From animation performance to theory, we cover everything needed to become a professional web animator. Whether you're a novice or professional web developer, this book is for everyone.Why is all of this so important? Why is it worth your time to become a professional motion designer? For the same reason that designers spend hours perfecting their pages’ font and color combinations, motion designers perfect their animations’ transition and easing combinations: Refined products feel superior. They leave users whispering to themselves, “Wow, this is cool”, right before they turn to a friend and exclaim, “You gotta try this.”

Effective JavaScript
“It’s uncommon to have a programming language wonk who can speak in such comfortable and friendly language as David does. His walk through the syntax and semantics of JavaScript is both charming and hugely insightful; reminders of gotchas complement realistic use cases, paced at a comfortable curve. You’ll find when you finish the book that you’ve gained a strong and comprehensive sense of mastery.” —Paul Irish, developer advocate, Google Chrome “This is not a book for those looking for shortcuts; rather it is hard-won experience distilled into a guided tour. It’s one of the few books on JS that I’ll recommend without hesitation.” —Alex Russell, TC39 member, software engineer, Google In order to truly master JavaScript, you need to learn how to work effectively with the language’s flexible, expressive features and how to avoid its pitfalls. No matter how long you’ve been writing JavaScript code, Effective JavaScript will help deepen your understanding of this powerful language, so you can build more predictable, reliable, and maintainable programs. Author David Herman, with his years of experience on Ecma’s JavaScript standardization committee, illuminates the language’s inner workings as never before—helping you take full advantage of JavaScript’s expressiveness. Reflecting the latest versions of the JavaScript standard, the book offers well-proven techniques and best practices you’ll rely on for years to come. Effective JavaScript is organized around 68 proven approaches for writing better JavaScript, backed by concrete examples. You’ll learn how to choose the right programming style for each project, manage unanticipated problems, and work more successfully with every facet of JavaScript programming from data structures to concurrency. Key features include Better ways to use prototype-based object-oriented programming Subtleties and solutions for working with arrays and dictionary objects Precise and practical explanations of JavaScript’s functions and variable scoping semantics Useful JavaScript programming patterns and idioms, such as options objects and method chaining In-depth guidance on using JavaScript’s unique “run-to-completion” approach to concurrency

Wie kann man JavaScript speichern?
JavaScript-Code kann in verschiedenen Dateiformaten gespeichert werden, wie z.B. .js, .html oder .txt. Man kann den Code einfach in einem Texteditor öffnen und als Datei mit der entsprechenden Dateiendung speichern. Alternativ kann man den Code auch in einem Code-Editor speichern, der speziell für die Entwicklung von JavaScript-Code entwickelt wurde.
-
Wie kann man mit JavaScript einen Text auf einer Website speichern?
Um einen Text auf einer Website mit JavaScript zu speichern, kann man entweder den LocalStorage oder den SessionStorage verwenden. Mit dem LocalStorage kann der Text dauerhaft gespeichert werden, während der SessionStorage nur für die aktuelle Browsersitzung gültig ist. Man kann den Text mit der Methode "setItem" speichern und mit der Methode "getItem" wieder abrufen.

Was ist das Problem mit JavaScript im Web?
JavaScript im Web hat einige Probleme. Zum einen kann es zu Sicherheitslücken führen, da es von bösartigem Code missbraucht werden kann. Zudem kann es zu Performance-Problemen kommen, da JavaScript auf der Client-Seite ausgeführt wird und die Ausführungsgeschwindigkeit vom Endgerät abhängt. Darüber hinaus kann JavaScript auch zu Inkompatibilitäten zwischen verschiedenen Browsern führen, da nicht alle Browser JavaScript gleich interpretieren.
-
Wie kann man Eingaben in JavaScript speichern?
In JavaScript können Eingaben in Variablen gespeichert werden. Dazu kann man den Wert eines Eingabefeldes mit Hilfe der Methode `document.getElementById()` abrufen und in einer Variable speichern. Alternativ kann man auch den Wert eines Eingabefeldes direkt in einer Funktion verwenden, ohne ihn in einer Variable zu speichern.

ppk on JavaScript
Whether you're an old-school scripter who needs to modernize your JavaScripting skills or a standards-aware Web developer who needs best practices and code examples, you'll welcome this guide from a JavaScript master. Other JavaScript books use example scripts that have little bearing on real-world Web development and are useful only in the chapter at hand. In contrast, Peter-Paul Koch's book uses eight real-world scripts he created for real-world clients in order to earn real-world money. That means the scripts are guaranteed to do something useful (and sellable!) that enhances the usability of the page they're used on. The book's example scripts include one that sorts a data table according to the user's search queries, a form validation script, a script that shows form fields only when the user needs them, a drop-down menu, and a data retrieval script that uses simple Ajax and shows the data in an animation. After an overview of JavaScript's purpose, Peter-Paul provides theoretical chapters on the context (jobs for JavaScript, CSS vs. JavaScript), the browsers (debugging, the arcana of the browser string), and script preparation. Then follow practical chapters on Core, BOM, Events, DOM, CSS Modification, and Data Retrieval, all of which are explained through a combination of theoretical instruction and the taking apart of the relevant sections of the example scripts.

Wie kann man Daten dauerhaft mittels JavaScript speichern?
In JavaScript kann man Daten dauerhaft speichern, indem man sie in den Local Storage des Browsers schreibt. Der Local Storage ist ein Speicherbereich, der auch nach dem Schließen des Browsers erhalten bleibt. Man kann Daten als Schlüssel-Wert-Paare speichern und später wieder abrufen.
-
Wie kann man JavaScript von einer Website trennen?
Um JavaScript von einer Website zu trennen, kann man verschiedene Ansätze verfolgen. Eine Möglichkeit ist es, das JavaScript in eine separate Datei auszulagern und diese dann in die Website einzubinden. Dadurch wird der HTML-Code übersichtlicher und das JavaScript kann leichter gewartet werden. Eine andere Möglichkeit ist es, das JavaScript nur bei Bedarf zu laden, zum Beispiel durch die Verwendung von Lazy Loading oder das Einbinden des Scripts erst nach dem vollständigen Laden der Website. Dadurch kann die Ladezeit der Seite optimiert werden.
-
Welche Website macht mein JavaScript unbrauchbar für andere?
Es gibt keine spezifische Website, die JavaScript unbrauchbar für andere macht. Allerdings kann schlecht geschriebener oder fehlerhafter JavaScript-Code dazu führen, dass eine Website nicht ordnungsgemäß funktioniert oder inkompatibel mit bestimmten Browsern oder Geräten ist. Es ist wichtig, sauberen und gut getesteten Code zu schreiben, um sicherzustellen, dass die Website für alle Benutzer funktioniert.
-
Wie kann ich JavaScript auf einer Website ändern?
Um JavaScript auf einer Website zu ändern, musst du den entsprechenden HTML-Code öffnen und den JavaScript-Code bearbeiten. Dies kann entweder direkt im HTML-Editor der Website oder in einem separaten Texteditor erfolgen. Nachdem du die gewünschten Änderungen vorgenommen hast, musst du die Datei speichern und die Änderungen auf der Website veröffentlichen, damit sie wirksam werden.
