One of the
most common activities of any JavaScript programmer, is to select elements on a
page, to make some change to it for whatever reason they have. Selecting an
element in JavaScript is not easy to say the least. You have to know the
individual element’s id attribute to be able to select it.
jQuery
selectors make selecting elements very easy. You can select elements using
jQuery based on many different element attributes.
The following
attributes can be used to select one or more elements using just one line of
code:
Id, class,
type, attributes values in attributes. There are many more that you will see as
you move through this tutorial.
The jQuery
object selector method comes in two forms.
First there
is the un-shortened method:
jquery()
Then there is
the shortcut method:
$()
Because it is
easier to use and because you will be using it so often, I suggest that you get
used to using the shortcut method. This method will return any element or
elements from a page that exists based on the selection attributes that you
pass it.
The beauty of
this is that, as you will see as you work through this tutorial, you can affect
one or many elements on a page, based on your selection attributes.
