JSON is not a scripting language, so I guess it's not possible this way.pimvdb– pimvdb2012-02-09 10:26:19 +00:00Commented Feb 9, 2012 at 10:26

if you use jquery
<script type="text/javascript">
var json_variable;
$.getJSON('url.json', function(json){
json_variable = json;
});
</script>

Are you aware of the jquery getJSON api? You can use this to download json from an url. Not sure if you can embed some json directly in a script tag, though.

You need to read in the contents from the url using AJAX and then put that into your variable or use the data as soon as you successfully get the data.
See here for non jQuery vanilla javascript methods: reading server file with javascript and also Consuming JSON data without jQuery (sans getJSON)
