Question

I use jQuery to get php-script result with ajax-function. Problem is php-script is on the another domain, so I should use “jsonp” as returned dataType, BUT php-script returns json, not jsonp (maybe script is not correct) and I get syntax error. How can I handle it? I suppose, that I can somehow get json string before ajax-function handles it and rises error, is it possible?

This is my ajax function:

$.ajax(
    {
        type: "POST",
        dataType: "jsonp",
        url: "http://www.pecom.ru/bitrix/components/pecom/calc/ajax.php",
        data: res,
        error: function (xhr, ajaxOptions, thrownError) {
            alert("error: " + xhr.status);
        },
        success: function (data) {
            alert("Data Loaded: " + data)
        }
    }
)

Thank you!

The short answer is that you can’t.

The longer one is that you have to set up some sort of proxying: make the request on the server side from a machine you control, transform the results to proper JSONP there, and connect to that server via AJAX.
(Or, in the very unlikely event that the target server supports CORS, you can use that instead of JSONP.)
