I'm working with Google Feed API for RSS feeds and need to add the values of the fetched RSS feed item array to create another array (that is used to create a javascript bar graph of the data).

The array would be this:

arrayOfData = new Array(
     [THE_FEED_ITEM_CONTENT, THE_FEED_ITEM_TITLE,'#cccccc']
);

I'm using jqBarGraph for the graph.

For context, this is the part of the code that displays the feed and subsequently grabs that values that I need to create the array mentioned. It is currently a part of creating a table of the of the data coming through the feed:

function displayfeed(result){

if (!result.error){
var thefeeds=result.feed.entries
for (var i=0; i<thefeeds.length; i++) {
xlabel+="<td>" +  thefeeds[i].title + "</td>";
xdata+="<td>" + thefeeds[i].content + "</td>";
}
rssoutput+=xlabel + "</tr></thead>" + xdata + "</tr></tbody></table>"
feedcontainer.innerHTML=rssoutput
}
else
alert("Error fetching feeds!")
}

window.onload=function(){
rssfeedsetup()
}

Here is an example of the array used to create the javascript graphs (with absolute values):

arrayOfData = new Array(
     [10.3,'Jan','#cccccc'],
     [15.2,'Feb','#cccccc'],
     [13.1,'Mar','#cccccc'],
);

Now, I need that array to be filled with:

arrayOfData = new Array(
     [thefeeds[i].content, thefeeds[i].title,'#cccccc']
);

The idea, of course, is to fill the array above with each item on the RSS feed. One line filled out with thefeeds[i].content & [thefeeds[i].title and so and so forth.

Thank you in advance for any advice.

Answer 1

var thefeeds=result.feed.entries;
var arrayOfData = new Array();
for (var i=0; i<thefeeds.length; i++) {
  arrayOfData.push([thefeeds[i].content,thefeeds[i].title,'#cccccc']) 
}

Answer 2

Loop through the array. This is not combining as it is usually defined (done with Array.concat in javascript)

var arrayOfData = new Array();
for(var feed in thefeeds) {
    arrayOfData.push(feed.content, feed.title, '#cccccc');
}
