Complete Reference/ JavaScript: TCR / Powell & Schneider / 9127-9 / Chapter 1 J avaScript is the premier client-side scripting language used today on the Web. Its use is widespread in tasks ranging from the validation of form data to the creation of complex user interfaces. Yet the language has capabilities that many of its users have yet to discover. Soon JavaScript will be increasingly used to manipulate the very HTML and even XML documents in which it is contained. When it finally achieves this role, it will become a first class client-side Web technology, ranking alongside HTML, CSS, and, eventually, XML. As such, it will be a language that any Web designer would be remiss not to master. This chapter serves as a brief introduction to the language and how it is included in Web pages.A First Look at JavaScript
Our first look at JavaScript is the ever-popular "Hello World" example. In this version we will use JavaScript to write the string "Hello World from JavaScript!" into the HTML document to be displayed:First JavaScript
Notice how the script is intermixed into the HTML document using the Doing so would probably throw an error in our browser window as shown in Figure 1-2. The reason for this is thattags are part of HTML, not JavaScript. Because the browser treats everything enclosed in In this case the tag surrounds the output from the JavaScript, which is displayed as boldface text by the browser. This example suggests the importance of understanding the intersection of HTML and JavaScript. In fact, before learning JavaScript, readers should fully understand the subtleties of correct HTML markup, especially given that most scripts will be used to produce HTML markup. Any JavaScript used within malformed HTML documents may act unpredictably, particularly if the script tries to manipulate HTML that is not well formed. A firm understanding of HTML is essential to writing effective scripts. Readers looking for more information on correct HTML usage should consult the companion book,HTML: The Complete Reference,3 rd
