    Thanks, i also found out that this was invalid json after checking with: JSONLint - The JSON Validator.

    Once correctly formatted, the response went into page. I like to keep square bracket as in this case i know there will be more objects entered.


    Correct format - tour.json:

    [
    {
    "description": "Paris, France Tour",
    "price": 2499.0,
    "nights": 7,
    "confirmation": "ef63kd"
    }
    ]

    Please "Wrap" code in code tags.
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
