如果你不需要通过.net但是ajax收集数据，你可以这样做：

的DropDownList：

<asp:DropDownList ID="CountryDDL" runat="server" Height="100%" onchange="requestfunc(this.options[this.selectedIndex].value)"></asp:DropDownList>

JavaScript的：

<script>
    function requestfunc(val){
    $(function () {
        $("[id$=OriginLocationTextBox]").autocomplete({
            source: function (request, response) {
                $.ajax({
                    url: "https://api.sandbox.amadeus.com/v1.2/airports/autocomplete",
                    dataType: "json",
                    data: {
                        apikey: "API KEY",
                        term: request.term,
                        country: val
                    },
                    success: function (data) {
                        response(data);
                    }
                });
            },
            minLength: 3,
        });
    });
    }
</script>
