DOM Storage and Microformats

Category: Firefox

John Resig has been writing about the bleeding edge features that will hopefully hit us around the Firefox 3 timeframe: DOM Storage and Microformat integration.

DOM Storage

John wanted to delve into DOM Storage and answered some of the questions posed such as:

• What’s to stop a script from filling an entire storage area with random data?
• Storing data to globalStorage[’localdomain’] (intranet global storage baybee)
• What’s with the name “DOM Storage”? (It is bad isn't it)
• The storage event
• Server-side Data

Microformats

Michael has already started developing the solid Microformat Parser, with Andy Mitchell, that will go into Firefox 3. And since this is part of the overall Firefox 3 Content Handling Requirements, it's a big priority for inclusion.

So, what could this content-handling API mean for you, the Firefox extension developer? It means that you would be able to write quick-and-dirty JavaScript to handle matched Microformats - and it'd be blazingly fast.

For example, here's some pseudo-code (any final result will, most likely, be very very different):

PLAIN TEXT

JAVASCRIPT:

1.  
2. Microformats.addHandler("hcard", function(card){
3.    var img = document.createElement("img");
4.    img.src = "hcard.gif";
5.    img.title = card.data.name + "'s Personal Information";
6.    card.container.appendChild( img );
7. });
8.  

It is fun to hear about the new features. Thanks to John for getting the word out.
