Question

I need to submit a form via ajax (not json) to another domain but keep getting the error

XMLHttpRequest cannot load http://some.other.domain/. Origin http://localhost:8081 is not allowed by Access-Control-Allow-Origin.

Is there a way to “fix” this?

$.ajax({
    type: "POST",
    dataType: "text/html",
    data: $("#surveyForm").serialize(),
    crossDomain: true,
    url: "http://some.other.domain",
    processData: false,
    error: function (jqXHR, textStatus, errorThrown) {
    },
    success: function (response) {
    }
});

Your best option might be to set up a proxy server. You can’t use JSON-P because you are doing a form POST, and you can’t use CORS because you don’t control the headers on the remote domain.
