{"product_id":"9780132704953","title":"ppk on JavaScript","description":"\u003cp\u003eWhether 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.\u003c\/p\u003e  \u003cp\u003eOther 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.\u003c\/p\u003e  \u003cp\u003eThe 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.\u003c\/p\u003e    \u003cp\u003eAfter 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.\u003c\/p\u003e","brand":"Pearson Education","offers":[{"title":"Default Title","offer_id":47147789713648,"sku":"9780132704953","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780132704953_p0.jpg?v=1763640479","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780132704953","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
