Jquery and JavaScript


This hands on JavaScript training course provides the knowledge necessary to design and develop dynamic Web pages using JavaScript. It introduces students to client-side JavaScript and how the language can be used to turn static HTML pages into dynamic, interactive Web pages. Students will learn the syntax of the JavaScript language and how client-side scripts interact with server-side programs. JavaScript topics include adding JavaScript to a Webpage, use of dialogs to interact with the user and JavaScript intrinsic objects such as Date, Array and Math. Students will also be introduced to the Document Object Model (DOM), creation of functions, event handling, form validation, JSON and Ajax. Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency
