    copied!<p>I have a problem with putting a variable into my array. Here is my code:</p> <pre><code>var info = new Array(); google.load("feeds", "1"); function initialize() { var feed = new google.feeds.Feed("http://www.ntvmsnbc.com/id/24927681/device/rss/rss.xml"); feed.setNumEntries(6); feed.load(function(result) { if (!result.error) { var container = document.getElementById("feed"); var html = ''; for (var i = 0; i &lt; result.feed.entries.length; i++) { var entry = result.feed.entries[i]; var a = " " ; a += entry.title; info[i] = a html += '&lt;p&gt;' + entry.publishedDate + '&amp;nbsp' + entry.title; } container.innerHTML = html; } alert(info[0]); }); //alert(info[0]); } //alert(info[0]); google.setOnLoadCallback(initialize); </code></pre> <p>You see an array called info. I'm trying to add entry.title into it. You can see some places are commented out. There my info[0] is empty. I can display my result only in function(result), except that it doesn't display anything like I never put anything inside my array. I didn't understand why. </p> <p>Updated:</p> <pre><code> var info = new Array(); google.load("feeds", "1"); function initialize(cb) { var feed = new google.feeds.Feed("http://www.ntvmsnbc.com/id/24927681/device/rss/rss.xml"); feed.setNumEntries(6); feed.load(function(result) { if (!result.error) { var container = document.getElementById("feed"); var html = ''; for (var i = 0; i &lt; result.feed.entries.length; i++) { var entry = result.feed.entries[i]; html += '&lt;p&gt;' + entry.publishedDate + '&amp;nbsp' + entry.title; cb(entry.title); } container.innerHTML = html; } }); } google.setOnLoadCallback(function(){ initizalize(processInfo);} ); function processInfo(information){ info[info.length] = information; alert(info[info.length]); } </code></pre> <p>Last Version</p> <pre><code> var info = new Array(); google.load("feeds", "1"); function initialize(cb) { var feed = new google.feeds.Feed("http://www.ntvmsnbc.com/id/24927681/device/rss/rss.xml"); feed.setNumEntries(6); feed.load(function(result) { if (!result.error) { var container = document.getElementById("feed"); var html = ''; for (var i = 0; i &lt; result.feed.entries.length; i++) { var entry = result.feed.entries[i]; var a= " "; a += entry.title; info[i] = a; html += '&lt;p&gt;' + entry.publishedDate + '&amp;nbsp' + entry.title; } container.innerHTML = html; } cb(info); }); } google.setOnLoadCallback(function(){ initizalize(processInfo);} ); function processInfo(info){ alert(info[0]); } </code></pre>
