For example, using JavaScript, you can make an image that changes colors when you hover your mouse over it or create a calculator that takes input from the user and returns a result (converts miles into kilometers for example). The actual JavaScript coding is placed on the same page as the HTML code; or, using the <SRC> tag, it can be placed in another file that is referenced from your HTML page. Java is a full-featured programming language whereas JavaScript is more of a collection of functions that can be used to add interactivity to a web page. This means that the items you reference (a window, image, form, etc) or new items that you create yourself are considered objects and JavaScript addresses objects in a manner that is not all that different then how you treat objects in the real world. First, an object should be given a name thatIn order to provide meaningful information to corporate intranet users and to attract more customers globally via World Wide Web, companies must build attractive Web sites that are responsive. JavaScript, a scripting language developed by Netscape, provides a powerful tool for rapidly building interactive, high-performance Web documents. This course covers all the major elements of JavaScript, taking the delegate from first principles through to competence in the language. Throughout this course, extensive hands-on exercises, performed under the expert tuition of an experienced instructor, provide delegates with practical experience of using JavaScript as well as providing tips and techniques so that delegates are equipped to use JavaScript immediately once they return to their place of work. Recommended for This course is valuable for those involved in establishing, developing or maintaining a Web site either on the Internet or on corporate JavaScriptOverview: JavaScript programming is useful for creating dynamic Web pages. It is used to detect and react to user initiated events, such as when the user moves his mouse over a link or image, or presses on a button or key. JavaScript can also improve a Web site with navigational aids, scrolling messages, rollovers, dialog boxes, dynamic images, shopping carts, etc. It has built-in objects that can be used to perform arithmetic calculations, string operations, manipulate the date and time, and validate form input such as e-mail addresses, zip codes, credit cards, etc. Benefits: Upon completion of this course, students will be able to: use the navigator and document object models to manipulate, navigate and program windows, frames, forms, images, etc. use JavaScript event handlers to respond to user initiated events use regular expressions to validate form data debug scripts Intended Audience: JavaScript Programming is an introductory course recommended for people developingJavaScript The JavaScript For Developers Part 1 training course from LearnKey starts with core concepts and takes you step-by-step through the process of creating richer, more dynamic client-side Web pages using JavaScript.

JavaScript For Developers Part 2 - Questions Section D: JavaScript Libraries Javascript - Introduction Duration: 3 days This course teaches developers to use JavaScript 1.5 for client-side scripting in web sites. It introduces JavaScript, explains its uses, and teaches the basics of scripting needed for the most common tasks used in web sites, taking students through these tasks step-by-step. Requirements: No prior scripting experience is required, although a good knowledge of HTML and general web development techniques is expected. Outline What is JavaScript Origins and JavaScript's original purpose Comparison to other common web programming languages Where can it be used The different versions of JavaScript Future directions for JavaScript Language structure Using JavaScript in HTML pages Embedding code v importing file Basic language syntax Variables Assignment operators Primitive data types Basic math and string operators Language blocks Block syntax Loops Comparison operators Conditional branches Arrays Defining and calling functions, parametersJavascript outlineJavaScript is a scripting language developed by Netscape that allows you to create dynamic web pages. JavaScript is not Java. It is a scripting language, very similar to C, that is parsed and then executed by the parser. This class provides you with the concepts and skills to use JavaScript effectively. You get hands-on practice working with basic through advanced techniques to get the most out of your experience. Prerequisites While we will make every reasonable effort to help, students with insufficient skills may be required to observe the class lessons or do their best to keep up without slowing down the rest of the class. Those wishing to familiarize themselves with JavaScript in order to add functionality to Websites, as well as to learn JavaScript for other applications. Class time is 9:00 a.m.- 4:00/4:30 p.m. Breaks are scheduled throughout the day and lunch is typically scheduled 12-1.This paper describes the new and improved editors of MyEclipse for JavaScript and CSS files. The JavaScript editor is available in HTML files and in separate JS files. The new and improved JavaScript Editor has a content assistant as you probably know from normal Java classes. It's available for all JavaScript document objects. The JavaScript Editor also supports syntax check and color coding. A new nice Outline View supports JavaScript methods and variables. You can test your javascripts without using a external browser. JavaScript options You can customize the JavaScript options within the preferences of MyEclipse. JavaScript is a programming language that you can use to add interactivity (tricks) to your Web pages. The JavaScript language needs to be placed within the HTML coding indicating that it is JavaScript. You should also note that only the newer versions of Browsers (MSIE 3+, Netscape 2+) can display JavaScript. Changing an image when a mouse pointer is moved over it. Have you ever wanted to have an image change to another image when you move your mouse pointer over it, and change back once you move your mouse pointer off it? This can be accomplished rather easily with JavaScript. First, you need to create two images then page is loaded I used the regular old HTML code to load the image: decide which image you want to load when the <img name="button" src="graphx/redbutton.gif" width="200" height="50" alt="a button" border="0"> Notice that I've given the image a name. This is very important, because it lets me identify the image on the page. Using JavaScript Java (developed by Sun Microsystems) is a powerful and very complex programming language - in the same category of languages like C and C++. JavaScript gives HTML designers a programming tool - HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! However, semicolons are required if you want to put more than one statement on a single line. Browsers that do not support scripts will display the script as page content. Scripts in a page will be executed immediately while the page loads into the browser. JavaScript also contains a conditional operator that assigns a value to a variable based on some condition. Perl is the programming language from which JavaScript modeled its regular expressions. The following JavaScript example creates a 5x5 matrix of rows and columns, similar to a game board. You can use this property to work with cookies in JavaScript.

Using JavaScript Browsers have a JavaScript interpreter built-in - not a plug-in JavaScript can bring pages alive without the overhead of large downloads (c.f. applets, Flash etc) Good security model - cannot read/write to the local disk.Each object has certain attributes. Some are like adjectives: properties. For example, an object might have a name, a size, and a text value. Some are like verbs: methods. JavaScript and VBScript are two of the most common scripting languages in use today. What is the Difference between Java and JavaScript? With JavaScript, you can write a script with a text editor (Notepad, SimpleText, etc.). JavaScript contains pre-defined objects, and you can create your own: - Within an anchor tag to call a JavaScript function.JavaScript This course teaches you to interact with web pages and Java Applets, input and show text as well as play sounds and display images or communicate with a plug-in response.
