title: Basic how-to for cross domain jsonp
body: <p>I looked everywhere here for this. I need just a simple "how-to" pull jsonp cross domain. I'm using jQuery 1.5.1.</p>
  
  <p>I tried the following in a program on another site:</p>
  
  <pre><code>$.getJSON("http://www.mydomain.com/testjson.json?jsoncallback=?", function(data) {
      alert("I'm hitting this.");
  }
  </code></pre>
  
  <p>This doesn't work at all.</p>
  
  <p>Is there a way of just doing a simple cross domain jquery JSONP call?</p>
  
  <p>Thanks</p>
