please help me use prototype to populate the 'title' div with the data inside this JSON.
      
JSON:
{
    "blogPosts" : [
        {
"postTitle" : "My Blog post title",
            "content" : "my main content",
            "image" : "th-4.jpg",
            }
    ]
}

html: <div id="title"></div>

Thanks!

That didn't work. btw I needed this to be done using prototype not jQuery.

I think in prototype it should look like this, but it's still not working, not sure what I'm doing wrong:
$('title').innerHTML = JSON.blogPosts.postTitle;

The path to get the title is :
myJson["blogPosts"][0].postTitle
or :
myJson.blogPosts[0].postTitle

To set the innerHTML you should use update : http://www.prototypejs.org/api/element/update
$('title').update(json.blogPosts.postTitle);
