parsererror错误：未使用jsonp调用jQuery

Question

我知道在SO中已经多次询问过，但使用这些答案并没有解决我的问题。

下面的脚本：

$(document).on('submit','.stack_survey_form',function(e) 
    {
        e.preventDefault();    

        var form = $(this);

        setPhoneAndAddress(form);

        if(form.attr('action') != '') {
            $.ajax({
                url: form.attr('action'),
                dataType: 'jsonp',
                contentType: "application/javascript; charset=utf-8",
                data: form.serialize(),
                error: function (jqXHR, text, errorThrown) {
                    console.log(jqXHR + " " + text + " " + errorThrown);
                    form.attr('data-sent','true').data('sent','true');
                },
                success: function(data) {
                    console.log(data);
                    console.log('SUCCESS');
                    form.attr('data-sent','true').data('sent','true');
                    submitForm();
                }
            });
            console.log('SENT');
        }else {
            console.log('SKIP');
        }

});

HTML表单：

<form method="get" name="hostedform" class="stack_survey_form" enctype="text" action="http://myurl.com/sendData/">
 //some content here
</form>

响应：

{"status":"lead_received","message":"Lead received for processing","lead_id":4177110}
