JSON - How to get specific value inside array?

Question

Given the below response, how would I get things like title?

jsonFlickrFeed({
    "title": "Thing",
    "link": "http://www.flickr.com/photos/tags/",
    "description": "",
    "items": [
   {
        "title": "Title",
        "link": "http://www.flickr.com/photos/123",
        "media": {"m":"http://farm6.staticflickr.com/123.jpg"},
   },
   {
        "title": "Title2",
        "link": "http://www.flickr.com/photos/1234",
        "media": {"m":"http://farm6.staticflickr.com/1234.jpg"},
   },
})

I want to do something like:

for (var i=0; i<xml.responseText.length;i++) {
    var x = (xml.responseText.items.title[i]);
    document.write(x)
}

What am I doing wrong here?

this is incomplete code. are we to infer that xml.responseText is some result of this mysterious jsonFlickrFeed function? — hubson bropa

@hubsonbropa The jsonFlickrFeed is what I get when I console.log(xml.responseText)... Wondering how to get specific things within jsonFlickrFeed — j_d

I'm not following what you mean by 'within'. I assume this function returns a javascript object and that you want to introspect that object. right? — hubson bropa

assuming xml.responseText is not null and is the defined result of the function in your question... reference the responseText.items length, not responseText. Then move your index from title to items:

for (var i=0; i < xml.responseText.items.length; i++) {
    var x = xml.responseText.items[i].title;
    document.write(x)
}
