> $(".highlight").removeClass;
The selector $('.highlight') is choosing all your objects that have
the class 'highligh'. removeClass still needs to know what class to
remove (ie, the method removeClass doesn't know how or why you
selected those particular elements). It takes the class name as an
argument, so to remove 'highlight' from everything that has the class
'highlight' you do this:
$('.highlight').removeCalss('highlight');
> $("this:even").addClass("shaded");
Note that 'this' is within quotation marks, so you're not actually
using the 'this' keyword. What $('this:even') means is: "Find every
even object of type 'this'". Of course, in html there is no 'this'
element.
To use it correctly, you'd use it like this: $(this) - note there are
no quotes. Think of it as referring to the 'subject' of a particular
function.
Eg, in the following piece of code:
$('#someDiv).click(function(){
$(this).hide();
});
$(this) refers to the the object that was clicked.
Eg2, in the following code:
$('h1').each(function(){
$(this).css('color': 'red');
});
$(this) refers to the particular 'h1' element that is being iterated
over.
Using ':even' narrows a selection of objects to only even ones. You
don't use it with 'this' (it doesn't really mean anything in that
context), but, for example you can do:
$('div:even').hide();
This would hide every second div element.
Hope this helps.
