Introduction to jQuery
Richard York · 2015
JavaScript frameworks have arisen as necessary and useful companions for client-side web development. jQuery is a phenomenally popular, leading JavaScript framework and application development platform. jQuery wraps around traditional, native JavaScript APIs to help a developer get more done with JavaScript using less code, allowing application development to go more quickly. Getting jQuery is extremely easy—all one has to do is go to www.jquery.com and click the Download jQuery link. With an example, the chapter shows how to install jQuery and execute a remedial “Hello, World” jQuery-based JavaScript application. It talks extensively about how to separate behavior (JavaScript) from presentation (CSS) and structure (XHTML). The chapter provides a generalized overview of programming conventions and good practice that one should follow. One should avoid detecting the user's browser, especially when it may lead to one group or another being locked out from functionality.
