Read JSON from URL

Question

I ran into a problem that should be really easy to solve, but I'm lost at the moment.

I have a url: http://search.twitter.com/search.json?q=bacon

Using JavaScript (not JQuery or PHP, just JavaScript), I want to read this JSON string and parse it. What is it.

Thanks!

You will be limited to SOP ( XMLHttpRequest can only be done in a URI in the same domain; JSON can only be retrieved using this method). To get around this, you will have to use JSONP instead ( another explanation * ).

The endpoint seems to support JSONP , so you can do:

 function foo(response) { // response is already a JavaScript object } var script = document.createElement("script"); script.src = "http://search.twitter.com/search.json?q=bacon&callback=foo"; document.body.appendChild(script);
