Answer 1

$('input[name=service]').val();

服务不是输入，而是选择。改为

$('select[name="service"]').val()

Answer 2

select元素没有价值，这就是为什么你必须获得所选选项的价值的原因。所以你得到这样的价值：

修改

正如 Todilo 注意到的那样，您正在尝试使用input代码获取元素，而select元素不是input。

$('select[name="service"] option:selected').val();

实施例

＆＃13;

console.log($('select option:selected').val());

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select>
<option>Option 1</option>
<option selected>Option 2</option>
</select>

＆＃13;

表单中的标记不起作用
