I have js only project. i call from my static index.html file the json file content.

I try(not works):

 $.getJSON('/js/test.json&callback=?',
   function() {
    alert('1111111111111111');
 },'jsonp');

Edit get in chrome: XMLHttpRequest cannot load file:///somefolder/test/data.json. Origin null is not allowed by Access-Control-Allow-Origin

Thanks

• javascript
• jquery
• ajax
• json
• jsonp

• why the (&callback=?) looks wrong! – ilyes kooli Commented Apr 27, 2012 at 14:52
• the callback should be used for JSON-P requests – Fabrizio Calderan Commented Apr 27, 2012 at 14:53

You are missing data variable in callback!

$.getJSON('/js/test.json', function(data) {
    console.log('JSON data received:', data);
});

You can retrieve json from a local source, it doesn't need to be jsonp, and even if it did what you are doing is not how you do it.

$.getJSON('http://yours./js/test.json',
   function() {
   alert('1111111111111111');
});
