软件简介

This plugin is intended to simplify the process of adding Google Analytics
tracking to a page, including the tracking of outbound links, mailtos, and
downloads, which are not otherwise tracked by default. Calling the plugin does
the following:

• Determine whether to include the SSL or non-SSL version of the GA script.
• Include the GA script (currently urchin.js, while ga.js is still in beta testing) from within try/catch to help suppress any issues GA may have from time to time.
• Set the _uacct variable to your GA tracking code.
• Call the urchinTracker() function once for the initial page load.
• Examine all of the links on the page and attach onclick events to external links, mailto links, and downloads.
• Call urchinTracker() when these links are clicked, prefixing them appropriately.

In addition to the tracking code, the prefixes used for each of the link types
above, as well as the extensions considered “downloadable files” are
configurable by the user.

It requires jQuery 1.2 or higher for the cross-domain $.getScript() call.
Usage is simply:

$.gaTracker('UA-XXXXX-XX');

Or you can specify options like so:

$.gaTracker( 'UA-XXXXX-XX', { external: '/external/', [mailto: ](mailto:         "mailto:        ") '/mailto/', download: '/downloads/', extensions: [ 'pdf','doc','xls','csv','jpg','gif', 'mp3', 'swf','txt','ppt','zip','gz','dmg','xml' ] } );
