Budding my newest JSON-based widgets was done with loads of trial and error, lacking a good understanding of
the JSON-format and lacking knowledge of how to admission the feed and retrieve
the data. So yesterday I did some investigate and developed a small javascript
program to examine the feeds. It is tech material, so don't be anxious if you
don't understand it.
I establish some
documentation on the blogger JSON feed format, based on Google Calendar. A little later
I discovered a simple tutorial on how to browse through JSON objects.
I tainted this into a
recursive javascript function, that browses the complete SON-feed-tree, and
displays all keys and all values. You can use is to research any J SON-feed.
Create a simple
HTML-page, using the following code.
<html>
<head>
<script
type='text/javascript'>
function
listkeys(feedobj,depth) {
for (key in feedobj) {
for (var i=0; i<depth;
i++) document.write('- ');
document.write(key+' =
'+feedobj[key]+'<br/>');
listkeys(feedobj[key],depth+1);}
}
function
showfeedcontent(json) {
listkeys(json,0);
}</script>
</head>
<body>
JSON FEED PARSER
<br/><br/>
<script
src="http://blognucleus.com/feeds/posts/default?alt=json-in-
script&callback=showfeedcontent"></script>
</body>
</html>
In this code restore the blognucleus.com
feed reference to your own blog's feed.
