POSplicing YouTube feed JSON result
text
Body
copied!<p>Say I have the following (phoney) feed result from YouTube using the Google Feed API.</p> <pre><code>{ "feed" : { "author" : "YouTube", "description" : "", "entries" : [ { "author" : "Foo", "categories" : [ "http://gdata.youtube.com/schemas/2007#video", "Entertainment", "golf", "resort" ], "content" : "Four friends are playing golf. Originally aired on 3/22/2011.", "contentSnippet" : "Four friends are still playing golf. Originally aired on ...", "link" : "http://www.linktoyoutubevid.com", "publishedDate" : "Thu, 24 Mar 2011 07:07:13 -0700", "title" : "Foobar" }, .....more feed entries here..... ], "feedUrl" : "http://www.myyoutubefeed.com", "link" : "http://www.youtube.com", "title" : "YouTube Videos", "type" : "atom10" }, "m" : "json", "status" : { "code" : 200 } } </code></pre> <p>I want to save this feed result (keeping the JSON format) to a variable, but I first want to strip out elements like categories, content, and contentSnippet. I tried using .splice but kept getting this error: Error: <code>feedResult.feed.entries[0].splice is not a function</code></p> <p>Here's part of my feed call:</p> <pre><code>feedUrl: opts.sourceUrl, type: "video", numEntries: 3, onFeedLoad: function(feedResult) { //alert(feedResult); formatVids(feedResult); var test = feedResult.feed.entries[0].splice(1,3); //alert(test); </code></pre> <p>What's the correct way to use .splice in this scenario? I could be getting confused as to whether I need to be splicing a JSON string or the JSON object. Is there a better solution?</p> <p>Thanks!</p>
