- What Ajax allows us to do. I had heard of Ajax before last week, and I could even remember what the acronym stood for (Asynchronous JavaScript and XML) but I didn’t realise what it actually does: allow applications to ‘retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.’ (Wikipedia).
- There’s no point worrying about learning JavaScript from scratch. Frameworks like jQuery are there to do the heavy lifting for you, although understanding the basics of programming (functions, arrays, expressions, operators etc.) is a big help.
- Embrace the DOM. It’s as simple to target elements with a framework like jQuery as it is with CSS.
- jQuery functions toggle! Perhaps the single most useful thing I learnt last week.
- There’s no need to be afraid. I’ve always been a bit intimidated by JavaScript, mainly because it speaks as if it were a programming language. Now though I feel that learning a framework like jQuery shouldn’t be any more difficult than learning CSS. Time to stop being a scaredy-cat and start getting my hands dirty
