<h3>Setting Up the Query</h3> |
|
|
84 |
<p>The easiest way to build a YQL query is by visiting the <a href="http://developer.yahoo.com/yql/console/">YQL Console</a>. In this example we will be using the <code><a href="http://developer.yahoo.com/yql/console/#h=select%20*%20from%20flickr.photos.recent">flickr.photos.recent</a></code> table. The <code>YQL</code> statement that we are using looks like this:</p> |
|
|
85 |
|
|
|
86 |
<pre class="code prettyprint">select * from flickr.photos.recent where (api_key = "1895311ec0d2e23431a6407f3e8dffcc")</pre> |
|
|
87 |
|
|
|
88 |
|
|
|
89 |
<h3>Setting Up the YUI Instance</h3> |
|
|
90 |
<p>Now we need to create our YUI instance and tell it to load the <code>yql</code> and <code>node</code> modules.</p> |
|
|
91 |
|
|
|
92 |
<pre class="code prettyprint">YUI().use('node', 'yql');</pre> |
|
|
93 |
|
|
|
94 |
|
|
|
95 |
<h3>Making the Query</h3> |
|
|
96 |
<p>Now that we have a YUI instance with the <code>yql</code> module, we can now make a query.</p> |
|
|
97 |
|
|
|
98 |
<pre class="code prettyprint">YUI().use('node', 'yql', function(Y) { |
|
|
99 |
|
|
|
100 |
var res = Y.one('#res'), count = 0, |
|
|
101 |
url = '<a href="http://flickr.com/photos/{owner}/{id}"><img src="http://static.flickr.com/{server}/{id}_{secret}_t.jpg"></a>'; |
|
|
102 |
|
|
|
103 |
var q = Y.YQL('select * from flickr.photos.recent where (api_key = "1895311ec0d2e23431a6407f3e8dffcc")', { |
|
|
104 |
//Tell JSONP to not cache this request so we get new images on each request |
|
|
105 |
allowCache: false, |
|
|
106 |
on: { |
|
|
107 |
success: function(r) { |
|
|
108 |
if (r.query && r.query.results) { |
|
|
109 |
count++; |
|
|
110 |
res.setHTML('<h2>Recent Flickr Photos <em>(query #' + count + ')</em></h2>'); |
|
|
111 |
Y.each(r.query.results.photo, function(v) { |
|
|
112 |
res.append(Y.Lang.sub(url, v)); |
|
|
113 |
}); |
|
|
114 |
} |
