No more initialize call needed for optimizing your page

In a previous post, we’ve seen that calling Sys.Application.notifyScriptLoaded is no longer needed. Another good news is that the Sys.Application.initialize call you could used to force Sys.Application to do its work is no longer needed because the library has changed and now initialization will be done during the DOMContentLoaded event (for standard compat browsers).

For IE, a trick is needed: a dumb element is created and the doScroll method is called successively until it doesn’t throw (throwing means that DOM still hasn’t been loaded). Not pretty, but it works.

Bottom line: MS AJAX has been improved and now the client code will be run as soon as possible (but not sooner than it should).

And that’s it. Stay tuned for more on MS AJAX.
