Question

我遇到警告中显示的问题编号问题。它不是显示问题编号，而是将问题ID显示为问题编号。因此，在警报验证中，它表示例如：

You have errors on question number: 115

例如，应该说You have errors on question number: 3

现在此代码显示问题ID：value="<?php echo$questionId?>"

此代码显示问题编号：echo$searchQuestionNo[array_search($questionId, $searchQuestionId)]

但是当我尝试这样做时：

<input type='hidden' id='num_groups' name='num_groups' value='<?php echo$searchQuestionNo[array_search($questionId, $searchQuestionId)]`?>'>

它不显示jquery警报的问题编号。说实话，发生的事情是验证不起作用，因为它没有出现。然而，如果我将上述代码保留为问题ID的值是什么：

<input type='hidden' id='num_groups' name='num_groups' value='<?php echo$questionId?>'>

然后它会在警报中显示问题ID，警报实际上有效。

所以我的问题是如何在警报中包含问题编号值，同时还能使验证工作，就像对问题一样？

下面是主要代码，以便您可以看到所有内容的来源：

PHP：

    <?

       // This will hold the search results
    $searchQuestionId = array();
    $searchQuestionNo = array();

    // Fetch the results into an array

   // get result and assign variables (prefix with db)
$stmt->bind_result($dbSessionId, $dbSessionName, $dbQuestionId, $dbQuestionNo, $dbQuestionContent, $dbAnswer, $dbAnswerId, $dbQuestionMarks, $dbOptionId, $dbOptionType);


        $searchQuestionId[] = $dbQuestionId;
        $searchQuestionNo[] = $dbQuestionNo;
      } 

?>



</head>

<body>


<form id="PenaltyMarks" action="<?php echo htmlentities($action); ?>" method="post">


<?php

$ques_ans = array();    //to store incorrect answers against ques no.

$q_occ_count = array_count_values($searchQuestionId);
foreach($searchQuestionId as $key => $questionId)
{
.....
}


?>
<table id='penaltytbl'>
<thead>
<tr>
<th class='questionth'>Question No.</th>
<th class='questionth'>Question</th>
</tr>
</thead>
<tbody>
<?php

foreach($ques_ans as $questionId => $inc_ans)
{


?>

<tr class="questiontd">

<td class="questionnumtd q<?php echo$searchQuestionNo[array_search($questionId, $searchQuestionId)]?>_qnum" rowspan="<?php echo$q_row_span?>"><?php echo$searchQuestionNo[array_search($questionId, $searchQuestionId)]?>
<input type="hidden" name="numQuestion" value="<?php echo$questionId?>" />
    </td>


<td class="answermarkstd">
<input class="individualMarks q<?php echo$questionId?>_mark"  q_group="1" name="answerMarks[]" type="text" data-type="qmark" data-qnum="<?php echo$questionId?>" onkeypress="return isNumberKey(event)" maxlength="3" value="0" />
</td>

</tr>
<?php
}

?>
</tbody>
</table>

<p>
<input type='hidden' id='num_groups' name='num_groups' value='<?php echo$questionId?>'>
<input id="submitBtn" name="submitPenalty" type="submit" value="Submit Marks" />
</p>

</form>

Jquery的：

  < script type = "text/javascript" >


    myClickHandler = function (e) {
      var ng = $('#num_groups').val();
      for (var group = 1; group 
           <= ng; group++) {
        if (!validation(group)) return false;
      }

    });


    function validation(group) {
      var msg = [];

      var nb = 0; // Number of blank values
      $("input[data-qnum='" + group + "']").each(function () {
        if ($(this).val() == '') {
          nb++;
          return false;
        }
      });
      if (nb != 0) {
        msg.push("\u2022 You have not entered in a value in all the Penalty Marks textbox \n");
      }

      if (msg.length >
          0) {
        alert("You have errors on Question Number: " + group + "\n\n" + msg.join("\n"));
        return false;
      } else {
        return true;
      }
    }




    < /script>

我认为，正如你所说，这段代码允许解答问题编号：

echo$searchQuestionNo[array_search($questionId, $searchQuestionId)]

在输入元素中添加您的问题编号作为属性q_number：

<input class="individualMarks q<?php echo$questionId?>_mark" q_number="<?php echo $searchQuestionNo[array_search($questionId, $searchQuestionId)]; ?>" q_group="1" name="answerMarks[]" type="text" data-type="qmark" data-qnum="<?php echo$questionId?>" onkeypress="return isNumberKey(event)" maxlength="3" value="0" />

并在validation函数

中使用它

function validation(group) {
  var msg = [];

  var qNumber = null;

  var nb = 0; // Number of blank values
  $("input[data-qnum='" + group + "']").each(function () {

    //Assign the question number
    qNumber = $(this).attr('q_number');

    if ($(this).val() == '') {
      nb++;
      return false;
    }
  });
  if (nb != 0) {
    msg.push("\u2022 You have not entered in a value in all the Penalty Marks textbox \n");
  }

  //Use qNumber instead of the group variable
  if (msg.length > 0) {
    alert("You have errors on Question Number: " + qNumber + "\n\n" + msg.join("\n"));
    return false;
  } else {
    return true;
  }
}
