Answer 1

$('<div/>') will not select a div from your html, but create a new one. Also it can be written like $('<div></div>'), first one is just a shorthand for second.

Answer 2

<div /> indicates that the div is a self closing div. It's basically shorthand for $('<div></div>').

Any browser that supports XHTML supports the self-closing syntax on all elements.

Answer 3

It means that the jquery function will not actually query for DIV elements but will create an jquery wrapped element of type <div></div> on which you can work on and append to the DOM eventually.

In your case, the code will create jquery object representing a DIV element, set its innerText to what the message variable contains and prepend it to the element with ID "log".

Answer 4

It means "create a jQuery-wrapped div element on the fly".

See http://api.jquery.com/jQuery/

From the above:

jQuery( html [, ownerDocument] )

Description: Creates DOM elements on the fly from the provided string of raw HTML.

Later...

When the parameter has a single tag, such as $('<img />') or $('<a></a>'), jQuery creates the element using the native JavaScript createElement() function.

So basically, it's like doing:

$(document.createElement("div")).text("blahblah");

Answer 5

It will create a new <div/> element and prepend it to the #log element.

Answer 6

It creates a new div tag and prepends it to log.
