The concept, behind the concept, behind jQuery

While selecting something and doing something is the core concept behind jQuery, I would like

to extend this concept to include creating something as well. Therefore, the concept behind

jQuery could be extended to include first creating something new, selecting it, and then doing

something with it. We could call this the concept, behind the concept, behind jQuery.

What I am trying to make obvious is that you are not stuck with only selecting something that is

already in the DOM. It is additionally important to grok that jQuery can be used to create new

DOM elements and then do something with these elements.

In the code example below, we create a new <a> element that is not in the DOM. Once

created, it is selected and then manipulated.

Sample: sample2.html

<!DOCTYPE html>

<body>

></script>

jQuery('<a>jQuery</a>').attr('href', 'http://www.jquery.com').appendTo('b

ody');

</script>

</body>

</html>

The key concept to pick up here is that we are creating the <a> element on the fly and then

operating on it as if it was already in the DOM.

jQuery requires HTML to run in standards mode or almost-standards

mode

There are known issues with jQuery methods not working correctly when a browser renders an

HTML page in quirks mode. Make sure when you are using jQuery that the browser interprets

the HTML in standards mode or almost standards mode by using a valid doctype.

To ensure proper functionality, code examples in this book use the HTML 5 doctype.

<!DOCTYPE html>

Google hosts several versions of the jQuery source code with the intent of it being used by

anyone. This is actually very handy. In the code example below I am using a <script> element

to include a minified version of jQuery that is hosted by Google.

Google also hosts several previous versions of the jQuery source code, and for each version,

minified and non-minified variants are provided. I recommend using the non-minified variant

during development, as debugging errors is always easier when you are dealing with non-

minified code.

A benefit of using a Google hosted version of jQuery is that it is reliable, fast, and potentially

cached.

Executing jQuery code when DOM is parsed without using ready()

The custom ready() event is not entirely needed. If your JavaScript code does not affect the

DOM, you can include it anywhere in the HTML document. This means you can avoid the

ready() event altogether if your JavaScript code is not dependent on the DOM being intact.

Most JavaScript nowadays, especially jQuery code, will involve manipulating the DOM. This

means the DOM has to be fully parsed by the browser in order for you to operate on it. This fact

is why developers have been stuck on the window.onload roller coaster ride for a couple of

years now.

To avoid using the ready() event for code that operates on the DOM, you can simply place

your code in an HTML document before the closing </body> element. Doing so ensures the

DOM is completely loaded, simply because the browser will parse the document from top to

bottom. If you place your JavaScript code in the document after the DOM elements it

manipulates, there is no need to use the ready() event.

In the example below, I have forgone the use of ready() by simply placing my script before the

document body closes. This is the technique I use throughout this book and on the majority of

sites I build.

Sample: sample5.html

<!DOCTYPE html>

<body>
