Hi there from a newbie,
I am pretty new to perl. I have recently read the following item from the monks:
Link to Javascript::SpiderMonkey Sample
I applaud the author for their work. Thanks. I understand learning more about this was left by the author of the write, as an exercise, but I am still confused. The main part for confusion is the section that has the following:
$js->property_by_path("document.location.href");
$js->property_by_path("window");
$js->property_by_path("navigator.userAgent");
$js->property_by_path("navigator.appVersion");
$js->function_set("toLowerCase", sub {return lc($_[0]); });
$js->function_set("javaEnabled", sub {undef});
I don't understand how one is suppose to figure out what to use here for a given script that I am trying to process. Is there anyone out there that can explain this in a little more detail, please?
Also, the author creates the evaluated response content from the headers of the returned information, plus the content of a page. Can someone explain the reason for including the header information?
I mainly just want to read in a file that is .js and identify links created by the script. Is there a generic way to define the
$js->property_by_path.....
$js->function_set.....
in a generic manner that should work for most scripts?
Thank you for your patience with this beginner.
