 Select elements typically have two values that you want to access. First there's the value to be sent to the server, which is easy:

 A jQuery object is an array-like wrapper around one or more DOM elements. To get a reference to the actual DOM elements (instead of the jQuery object), you have two options. The first (and fastest) method is to use array notation:

 Either the `:eq()` selector or the `.eq()` method will allow you to select the proper item. However, to replace the text, you must get the value before you set it:

 }</script>
 
 Because jQuery uses CSS syntax for selecting elements, some characters are interpreted as CSS notation. For example, ID attributes, after an initial letter (a-z or A-Z), may also use periods and colons, in addition to letters, numbers, hyphens, and underscores (see [W3C Basic HTML Data Types](http://www.w3.org/TR/html4/types.html#type-id)). The colon (":") and period (".") are problematic within the context of a jQuery selector because they indicate a pseudo-class and class, respectively.

 This code selects an element with an ID of "myDivId". Since IDs are unique, this expression always selects either zero or one elements depending upon whether or not an element with the specified ID exists.

 If you have a variable containing a DOM element, and want to select elements related to that DOM element, simply wrap it in a jQuery object.
