Some modern browsers have support for parsing JSON into a native object: var var1 = ‘{“cols”: [{“i” ……. 66}]}’; var result = JSON.parse(var1); For the browsers that don’t support it, you can download json2.js from json.org for safe parsing of a JSON object. The script will check for native JSON support and if it doesn’t … Read more
Alright. In case anyone needs to know in the future…In hindsight, the solution probably should have been more obvious than it was, but you need to have the web-response write directly to the response stream. Simply returning a string of JSON doesn’t do it, you need to someone construct it and stream it back. The … Read more

To make JavaScript Fetch/XHR requests to Wikipedia, add origin=* to the URL query params. So the base of the URL in the question should be like this: https://en.wikipedia.org/w/api.php?origin=*&action=query… See the CORS-related docs for the Wikipedia backend: For anonymous requests, origin query string parameter can be set to * which will allow requests from anywhere. 2016-05-09 … Read more
JSONP is not JSON. A JSONP response would consist of a JavaScript script containing only a function call (to a pre-defined function) with one argument (which is a JavaScript object literal conforming to JSON syntax). The response you are getting is JSON, not JSONP so your efforts to handle it as JSONP fail. Change dataType: … Read more

Actually, you just have to add ?callback=?, jQuery does the rest. $(document).ready(function() { $.getJSON(‘http://example.com/api/get_cats?callback=?’, function(fbResults) { document.write(fbResults.cats[0].title); }); });
You need to use JSONP for a cross-domain call to get round the browser restrictions, and to update your web.config with crossDomainScriptAccessEnabled set to true to get round server ones. There’s a good example in the answer here: how to avoid cross domain policy in jquery ajax for consuming wcf service? You may also have … Read more
