Question

Activity Level<br>
        <input type = "radio" id="activitylevel" value="sedentary">Sedentary - Little or no exercise, desk job</option><br>
        <input type = "radio" id="activitylevel" value="lightly">Lightly active - Light exercise or sports 1-3 days/wk</option><br>
        <input type = "radio" id="activitylevel" value="moderately">Moderately active  Moderate exercise or sports 3-5 days/wk</option><br>
        <input type = "radio" id="activitylevel" value="very">Very active - Hard exercise or sports 6-7 days/wk</option><br>
        <input type = "radio" id="activitylevel" value="extremely">Extremely Active - Hard daily exercise or sports & physical labor job or 2 X day training, football camp, etc.</option><br>

这有什么问题吗？我花了一个小时看着我的其余代码，弄清楚为什么我不能拉出这个表单上发送的值，我开始认为这个代码有问题。有任何想法吗？我在网上看了一些例子，他们不使用'id'？

谢谢，一个非常noobie的问题，但任何指针或帮助表示赞赏。

Answer 1

我认为，您忘记写名称）所有无线电输入的名称必须相同，例如name="radio_name"。写如下。但是html中的id必须不一样。为什么你使用我无法理解。

<input type="radio" name="activitylevel" id="activitylevel_1"  value="sedentary">Sedentary - Little or no exercise, desk job<br>
<input type = "radio" name="activitylevel" id="activitylevel_2" value="lightly">Lightly active - Light exercise or sports 1-3 days/wk<br>
<input type = "radio" name="activitylevel" id="activitylevel_3" value="moderately">Moderately active  Moderate exercise or sports 3-5 days/wk<br>
<input type = "radio" name="activitylevel" id="activitylevel_4" value="very">Very active - Hard exercise or sports 6-7 days/wk<br>
<input type = "radio" name="activitylevel" id="activitylevel_5" value="extremely">Extremely Active - Hard daily exercise or sports & physical labor job or 2 X day training, football camp, etc.<br>

Answer 2

您必须为单选按钮定义名称

像这样

<input type = "radio" id="activitylevel" name="activitylevel" value="sedentary">

Answer 3

您需要设置每个输入字段名称，然后在尝试检索值时引用该名称。例如：

<input type = "radio" name="activitylevel">Sedentary - Little or no exercise, desk job</option><br>

Answer 4

提交表单时，不会提交没有姓名的输入。因此，您需要为输入添加名称。似乎也存在一些语法错误。更正后的代码如下所示：`

<input type = "radio" id="activitylevel1" value="sedentary" name="activitylevel">Sedentary - Little or no exercise, desk job</input>
        <input type = "radio" id="activitylevel2" value="lightly" name="activitylevel">Lightly active - Light exercise or sports 1-3 days/wk</input>
        <input type = "radio" id="activitylevel3" value="moderately" name="activitylevel">Moderately active  Moderate exercise or sports 3-5 days/wk</input>
        <input type = "radio" id="activitylevel4" value="very" name="activitylevel">Very active - Hard exercise or sports 6-7 days/wk</input>
        <input type = "radio" id="activitylevel5" value="extremely" name="activitylevel">Extremely Active - Hard daily exercise or sports & physical labor job or 2 X day training, football camp, etc.</input>`
