Javascript Php无法检索动态生成的文本字段

我无法检索使用javascript创建的动态生成的文本字段和单选按钮，但能够检索使用html手动添加到表单中的文本字段和单选按钮

以前，我使用样式来隐藏和显示我的所有文本字段，而不是动态创建的文本字段，因此我获取所有文本字段没有问题，并且可以安全地假设我的PHP处理没有任何问题

我的HTML/界面编码

<?php
for ($x = 1; $x <= 5; $x++)
{
    $inputAreaID = "inputArea".$x;// Creating all dynamic options and etc in this div using javascript 
    $typeID = "type".$x; //for select type id
    $opt2ID = "ans".$x; 
    $optID = "opt".$x; 
    $comID = "com".$x; 
    $qnName = "qn".$x // for qn textfield name?>
<table>
    <tr>
        <td>Question <?php echo $x ?></td>
        <td><input type="text" name='<?php echo $qnName ?>' required></td>
    </tr>

    <tr>
        <td>Question Type</td>
        <td>
        <select id="<?php echo $typeID ?>" name="<?php echo $typeID ?>" onclick="showQuestionSelect('<?php echo $x ?>', '<?php echo $typeID ?>', '<?php echo $inputAreaID ?>')">
        <option value="">Please select one option </option>                 
            <option value="Yes,No">Yes/No </option>
            <option value="True,False">True/False</option>
            <option value="3">A. B. C. D.</option>
        </select>
        </td>
    </tr>
 </table>   
        <div id='<?php echo $inputAreaID ?>' style="margin-bottom: 1px;margin-top:1px;"></div>

问题:
首先，您应该检查服务器是否已获得这些生成的文本字段的值。尝试显示
$\u POST[]
的所有成员

我猜你被困在参数的名称中了
我已经回显了我的$\u帖子[]；但是我没有把它放在上面的代码里。我已经使用这个名称进行了测试，通过硬编码我的html名称并创建“testtextfield”来硬编码gui文件中动态生成的测试的名称。结果能够通过我的处理php代码得到检索。我正在使用innerhtml生成文本字段。这是否会影响我是否能够检索动态生成的文本字段？
function showQuestionSelect(questionNo, typeID, inputArea) 
{
var s = String(typeID);
var i = String(inputArea);
var e = document.getElementById(s);
var selectedOpt = e.options[e.selectedIndex].value;

ansID = questionNo + "_ans";
comID = questionNo + "_com";
optA = questionNo + "_optA";
optB = questionNo + "_optB";
optC = questionNo + "_optC";
optD = questionNo + "_optD";

var msg = "";


if (selectedOpt == "True,False")
{
    msg ="<div style='margin-bottom: 10px;margin-top:10px;'><input type='radio' name='"+ ansID + "' value='True'> Submit True as Answer<input type='radio' name='" +ansID +"' value='False'> Submit False as Answer</div>";     
    msg +="<div style='margin-bottom: 10px;margin-top:10px;'>Reason for the answer: <input type='text' name='" + comID + "' value='' /></div>"
}
else if (selectedOpt == 3)
{
    msg = "<div style='margin-bottom: 10px;margin-top:10px;'>";
    msg += "Option A: <input type='text' name='" + optA + "' value='' /> <input type='radio' name='" + ansID + "' value='" + optA + "'> Submit as Answer  <br><br>";
