How to extract url data from Reddit API using JSON

问题

I'm trying to extract the image post URLs from a subreddit feed, and render <img> elements on my page.

Been trying to hack together the .getJSON() Flickr example from the jQuery Docs for a while now and I'm not getting anywhere.

Code in question:

$.getJSON('http://www.reddit.com/r/pics.json', function (data) {
  $.each(data.children, function (i, item) {
    $('<img/>').attr("src", url).appendTo("#images");
  });
});

In the body, I have the element: div#images

I understand that I need to use JSONP, but not sure how. Can somebody point me in the right direction?

回答1:

You are using the wrong url. Use this:

$.getJSON("http://www.reddit.com/r/pics/.json?jsonp=?", function(data) { 
    // Do whatever you want with it.. 
});

EDIT : Working example based on your fiddle in the comments.

$.getJSON("http://www.reddit.com/r/pics/.json?jsonp=?", function(data) { 
    $.each(data.data.children, function(i,item){
        $("<img/>").attr("src", item.data.url).appendTo("#images");
    });
});

You should use data.data.children and not data.children
