JavaScript 来自 DropDownList 选择的属性值

Question

我有一个 DropDownList，其中包含从 SQL 服务器数据库填充的文本字段和值字段。我希望获得用户选择的值字段并输入到 JavaScript 中 "term: request term" 下面的 "country: "。感谢这里的每一位成员的帮助。

下拉列表：

<asp:DropDownList ID="CountryDDL" runat="server" Height="100%"></asp:DropDownList>

JavaScript:

<script>
    $(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: 
                    },
                    success: function (data) {
                        response(data);
                    }
                });
            },
            minLength: 3,
        });
    });
</script>

如果您不想通过 .net 收集数据但 ajax，您可以这样做：

下拉列表:

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

JavaScript:

<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>
