फ़ीड को पार्स करना
(वास्तव में सिफारिश नहीं है कि एक, अन्य विकल्प देखें)
jQuery.getFeed({
url : FEED_URL,
success : function (feed) {
console.log(feed.title);
// do more stuff here
}
});
के साथ jQuery के निर्मित में XML समर्थन
$.get(FEED_URL, function (data) {
$(data).find("entry").each(function () { // or "item" or whatever suits your feed
var el = $(this);
console.log("------------------------");
console.log("title : " + el.find("title").text());
console.log("author : " + el.find("author").text());
console.log("description: " + el.find("description").text());
});
});
$.ajax({
url : document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(FEED_URL),
dataType : 'json',
success : function (data) {
if (data.responseData.feed && data.responseData.feed.entries) {
$.each(data.responseData.feed.entries, function (i, e) {
console.log("------------------------");
console.log("title : " + e.title);
console.log("author : " + e.author);
console.log("description: " + e.description);
});
}
}
});
लेकिन इसका मतलब है कि आप उन पर भरोसा कर रहे हैं जो ऑनलाइन और पहुंच से बाहर हैं।
भवन निर्माण सामग्री
एक बार जब आप सफलतापूर्वक जानकारी आप फ़ीड से जरूरत निकाला है, आप बना सकते हैं DocumentFragmentके साथ ( document.createDocumentFragment()के साथ बनाया तत्वों (युक्त document.createElement()) आप अपने डेटा प्रदर्शित करने के लिए इंजेक्षन करना चाहते हैं।
सामग्री का इंजेक्शन लगाना
उस कंटेनर तत्व का चयन करें जिसे आप पृष्ठ पर चाहते हैं और अपने दस्तावेज़ के टुकड़े उसमें जोड़ दें, और इसकी सामग्री को पूरी तरह से बदलने के लिए इनर HTML का उपयोग करें।
कुछ इस तरह:
$('#rss-viewer').append(aDocumentFragmentEntry);
या:
$('#rss-viewer')[0].innerHTML = aDocumentFragmentOfAllEntries.innerHTML;
परीक्षण डेटा

<summary type="html"><h1>Parsing the Feed</h1>
<h3>With jQuery's jFeed</h3>
<p>Try this, with the <a href="http://plugins.jquery.com/project/jFeed" rel="nofollow">jFeed</a> <a href="http://www.jquery.com/" rel="nofollow">jQuery</a> plug-in</p>
<pre><code>jQuery.getFeed({
url : FEED_URL,
success : function (feed) {
console.log(feed.title);
// do more stuff here
}
});
</code></pre>
<h3>With jQuery's Built-in XML Support</h3>
<pre><code>$.get(FEED_URL, function (data) {
$(data).find("entry").each(function () { // or "item" or whatever suits your feed
var el = $(this);
console.log("------------------------");
console.log("title : " + el.find("title").text());
console.log("author : " + el.find("author").text());
console.log("description: " + el.find("description").text());
});
});
</code></pre>
<h3>With jQuery and the Google AJAX APIs</h3>
<p>Otherwise, <a href="https://developers.google.com/feed/" rel="nofollow">Google's AJAX Feed API</a> allows you to get the feed as a JSON object:</p>
<pre><code>$.ajax({
url : document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&amp;num=10&amp;callback=?&amp;q=' + encodeURIComponent(FEED_URL),
dataType : 'json',
success : function (data) {
if (data.responseData.feed &amp;&amp; data.responseData.feed.entries) {
$.each(data.responseData.feed.entries, function (i, e) {
console.log("------------------------");
console.log("title : " + e.title);
console.log("author : " + e.author);
console.log("description: " + e.description);
});
}
}
});
</code></pre>
<p>But that means you're relient on them being online and reachable.</p>
<hr>
<h1>Building Content</h1>
<p>Once you've successfully extracted the information you need from the feed, you need to create document fragments containing the elements you'll want to inject to display your data.</p>
<hr>
<h1>Injecting the content</h1>
<p>Select the container element that you want on the page and append your document fragments to it, and simply use innerHTML to replace its content entirely.</p>
