ClickTagger Breakdown
Okay, are you ready to break this down? Because based on the rest
of this chapter, it
s start out by taking a
look at Table 12.7 and the variables that are instantiated at the top
of the class.
And now let
'
s time for that step, so let
'
s jump right into the ClickTagger constructor,
which requires only one parameter of type LoaderInfo, which is
very creatively named
loaderInfo
. The LoaderInfo class provides
plenty of information about our .swf including the parameters that
have been passed in to it like flashvars with clickTags. To get to
those parameters, we need not look any further than, you guessed
it, the
parameters
property of our
loaderInfo
to get the object that
contains all the name-value pairs that have been sent in to the
banner. Once we have those name-value pairs, we
'
re going to run
through them, convert them to lowercase, and test them against
our
_tagName
of
'
“
clicktag.
”
If we catch one that matches, we check
