 You must use a cross domain request.  
 "jsonp": Loaded in JSON block using JSONP. Additional "? Callback =?" Adds a crawling string parameter, "_ = [TIMESTAMP]" to disable the caching until the cache option is set to the right at the end of your url to specify the callback.  
 Try this type  
  $ (document) .ready (function () {var url = "http://developers-blog.org/resources/jquery -ajax / heroes-list.json "; $ .getJSON (url +"? Callback =? ", Work (data) {console.log (data); alert (data); $ .eec (data, function (i, Name) {$ ("div"). Enclosed (name + "");}}}});
