如何獲取輸入值

我有一個問題，我不知道如何<select><option> </option></select>從這里的單選按鈕中讀取存盤的值，我的代碼包含 js 和 html

        function inport(){
            var name = document.getElementById("name").value;
            var index = document.getElementById("index").value;
            var phone = document.getElementById("phone").value;
            var grade = document.getElementById("grade").value;
            var session = document.getElementById("session").value;
            console.log(name);
            console.log(index);
            console.log(phone);
            console.log(grade);
            console.log(session);

        }


    

    <form>
    <div>
        <h1>Details</h1>
    <div>
        <label>Name</label>
        <input type="text" id="name">

            <option value="checkbox">April</option>
            <option value="checkbox">March</option>
            <option value="checkbox">February</option>
            <option value="checkbox">January</option>
        </select>

    </div>
    <div>
        <input type="button" value="Input student"id="import" onclick="inport();">

在輸入中添加名稱屬性。

JS代碼

document.getElementById("show_radio").onclick = function () {
        var radio = document.getElementsByName("gender");
        
        var radio_selected;
        
        for (var a = 0;  a < radio.length; a  ) {
            if (radio[a].checked) {
                radio_selected = radio[a].value;
            }
        }
        
        document.getElementById("selected_radio").innerHTML = radio_selected;
        
        }

<form>

                    <input type="radio" name="gender" value="Male" checked=""> Male<br>
                    <input type="radio" name="gender" value="Female"> Female<br>
                    <input type="radio" name="gender" value="I'd rather not inform"> I'd rather not inform
                    
                </form>
                
 <button id="show_radio">Show</button>
 
    <p id="selected_radio"></p>
