這兩個範例使用 global 方法, google.feeds.findFeeds 與 google.feeds.lookupFeed.
首先使用 google.feeds.findFeeds 來搜尋將結果動態的顯示在 FeedControl.
Code:
<![CDATA[
<html>
<head>
<script type="text/javascript" src="http://www.google.com/jsapi?key=YOUR-KEY"></script>
<script type="text/javascript">
google.load("feeds", "1");
var defaultQuery = 'Official Google Blogs';
function findFeeds(query) {
google.feeds.findFeeds(query, feedSearchDone);
}
function feedSearchDone(result) {
var el = document.getElementById('feedControl');
if (result.error || result.entries.length <= 0) {
el.innerHTML = 'No Results Found';
return;
}
// Create a feed control
var feedControl = new google.feeds.FeedControl();
// Grab top 4..
for (var i = 0; i < 4; i++) {
feedControl.addFeed(result.entries[i].url, result.entries[i].title);
}
feedControl.setLinkTarget(google.feeds.LINK_TARGET_BLANK);
feedControl.setNumEntries(2);
feedControl.draw(el);
}
google.setOnLoadCallback(function() {findFeeds(defaultQuery)});
</script>
</head>
<body>
<div id="feedControl">Loading</div>
</body>
</html>
]]>

第二個範例使用
google.feeds.lookupFeed, 輸入 Flickr 帳號, 然後動態的展示該帳號的照片.
Code:
<![CDATA[
<html>
<head>
<script type="text/javascript" src="http://www.google.com/jsapi?key=YOUR-KEY"></script>
<script src="http://www.google.com/uds/solutions/slideshow/gfslideshow.js" type="text/javascript"></script>
<script type="text/javascript">
google.load("feeds", "1");
var defaultUser = 'dlc0421';
function newSlideShow(user) {
showStatus('Resolving feed for ' + user);
var url = 'http://www.flickr.com/photos/' + user;
google.feeds.lookupFeed(url, lookupDone);
}
function lookupDone(result) {
if (result.error || result.url == null) {
showStatus('Could not locate feed for user');
return;
}
showStatus('Found Photo Feed');
// We need to switch over from Atom to RSS to get Yahoo Media for slideshow..
var url = result.url.replace('format=atom', 'format=rss_200');
showSlideShow(url);
}
function showSlideShow(url) {
var options = {
displayTime: 2500,
transistionTime: 800,
scaleImages: true,
thumbnailTag: 'content',
linkTarget : google.feeds.LINK_TARGET_BLANK
};
new GFslideShow(url, "slideshow", options);
}
function showStatus(msg) {
var ss = document.getElementById("feeds-5-div-2");
ss.innerHTML = '<div class=\"feed-loading\">' + msg + '</div>';
}
google.setOnLoadCallback(function() {newSlideShow(defaultUser)});
</script>
</head>
<body>
<div id="slideshow">Loading</div>
</body>
</html>
]]>
