Adding local json data without ajax request

I need to include a json file from a local directory while ajax requests did not work in some browsers (due to cross domain security issues). The final solution turned out to be quite simple, just adding a variable definition before the xml code:

var json = 
[
 {
    "id":"0",
    ...
  }
];
var json = JSON.parse(json);

and including it as as the first script being loaded

<script src="js/json.js"></script>

The json var can then be processed in all other scripts.
