New JSON feed of my blog

Some javascript messing about

Oh that'll come in handy for all those mashups based around me you've been planning... Not a straight feed of what I post every day, it searches the content of the site, probably seven or eight years worth of postings now.

JSON is "javascript object notation" btw (if you have no interest in javascript best stop reading now), presenting information in such a format you can slot it straight into a script without any more processing needed. XML is great for passing info around the web, except that AJAX requests specifically block you from fetching XML from another website, but you can call javascript from anywhere happily.

It works in the same way as the xml feeds, construct your call to my JSON API (ooh, get me) like this:

http://www.clarkeology.com/javascript/your_callback_goes_here/squirrel+and+magpie.js

And that'll return something like:

callback_goes_here( [{guid:10701,

Hmm, will reformat that later so it looks nicer here (don't know where all those backslashes came from, they're not there in the real json), and also I should investigate if there is an rss style standard for json blog feed, it's all very well me saying "my blog titles are called mSubject" but if no-one else is using that it's not really going to catch on for blogs... If you don't know what that is, then just come back later, I'm sure to post something about squirrels again soon.

To use these feeds of mine, you want to put some javascript on your page that grabs that feed and does something with it. If you're using the newer version of jquery.com say, you can whack some of my content into your page like this:



// hmm, bah just realised I've done something fundamentally unhelpful, I really do need to have "callback=" in my standard js url to fit in with other people's requirements...

$.getJSON("http://www.clarkeology.com/javascript/callback_goes_here/search.js jsoncallback=?",
function( js ){
for ( var i in js ) {
$('body').append( '<' + 'h2>' + js[i].title + '<' + '/a><' + '/h2><' + 'p>' + js[i].description + '<' + '/p>' ); }
});



I'm doing that on yourfolkestone.com/javascript

Will be extending this to cover other content soon, ie a list of pubs local to a particular postcode or something like that, won't that be nice?
