您好我正在尝试将参数传递给 javascript 函数getConfirmation()，我的代码如下。根本不执行对函数的调用。所以我想我打电话给它会出错。请帮忙。

<html>
<head>
<script type="text/javascript">
<!--
function getConfirmation(var value1)
{

   var retVal = confirm("Pop Code:" + value1 + "\n" + "Amount:" + "" + "\n" + "Updated Balance:" + "" + "\nPlease confirm!");
   if( retVal == true )
   {
      alert("User wants to continue!");
      return true;
   }else{
      alert("User does not want to continue!");
      return false;
   }
}
//-->
</script>
<body>
<div align="center" style="width:100%; margin: 0px auto;">

<div align="center" style="width:100%; margin: 0px auto; background-color:f0f0f0">
<div id="child" style="  align="center" style="width:100%; margin:0px auto;" >
<div style=" right:5%; top:5%; z-index: 100; position:absolute;">

</div>
<img src = "images/header.png" width ="100%"  />

</div>
</div>
<div align="center">
<?php
require 'config.php';
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die('Cannot select database');
$query = "SELECT * FROM cust_info;";
$result = mysql_query($query) or die(mysql_error());

echo "</br>";
echo "<table border='1'>
<tr>
<th>Pop Code</th>
<th>Open_Date</th>
<th>Maturity_Date</th>
<th>Amount</th>
<th>Balance</th>
<th>Col Amount</th>
</tr>";

while($row1 = mysql_fetch_array($result))
  {
  if ($row1['status'] == 'DONE')
  {
  continue;
  }
  echo "<div class=\"addform\"><form method='post' action=\"txn.php\">\n";
  echo "<tr>";
  echo "<td><input type='hidden' name='pop_code' value='".$row1['pop_code']."'>" . $row1['pop_code'] . "</td>";
  echo "<td><input type='hidden' name='open_date' value='".$row1['open_date']."'>" . $row1['open_date'] . "</td>";
  echo "<td><input type='hidden' name='mat_date' value='".$row1['mat_date']."'>" . $row1['mat_date'] . "</td>";

  echo "<td>" . "   <input type=\"text\" name=\"amount\"/>\n" . "</td>";
  //echo "<td>" . "<input type=\"button\" value=\"Make Entry\" onclick=\"getConfirmation();\"" . "</td>";
  echo "<td>" . "   <input type=\"image\" src=\"images/update.png\" onclick=\"getConfirmation(".$row1['pop_code'].");\" alt=\"Update Row\" class=\"update\" title=\"Update Row\">\n" . "</td>";
  echo "</tr>";
  echo "</form></div>";
  }
echo "</table>";
?>
<div align="center" style="width:100%; margin: 0px auto;">
<img src="images/footer.png" style="width:100%;"/>

它应该是：

function getConfirmation(value1){

和形式：

echo "<div class=\"addform\"><form method='post' action=\"txn.php\" onsubmit=\"return getConfirmation('".$row1['pop_code']."');\">";

并且您可以不理会提交图像而无需任何 javascript 调用。

最终代码：

  echo "<div class=\"addform\"><form method='post' action=\"txn.php\" onsubmit=\"return getConfirmation('".$row1['pop_code']."',this,'".$row1['balance']."');\">\n";
  echo "<tr>";
  echo "<td><input type='hidden' name='pop_code' value='".$row1['pop_code']."'>" . $row1['pop_code'] . "</td>";
  echo "<td><input type='hidden' name='open_date' value='".$row1['open_date']."'>" . $row1['open_date'] . "</td>";
  echo "<td><input type='hidden' name='mat_date' value='".$row1['mat_date']."'>" . $row1['mat_date'] . "</td>";
  echo "<td><input type='hidden' name='depoamt' value='".$row1['depoamt']."'>" . $row1['depoamt'] . "</td>";
  echo "<td><input type='hidden' name='balance' value='".$row1['balance']."'>" . $row1['balance'] . "</td>";
  echo "<td><input type=\"text\" name=\"amount\"/>\n</td>";
  echo "<td><input type=\"image\" src=\"images/update.png\" alt=\"Update Row\" class=\"update\" title=\"Update Row\">\n</td>";
  echo "</tr>";
  echo "</form></div>";

和 javascript：

<script type="text/javascript">
<!--
function getConfirmation(value1,form,balance)
{

   var retVal = confirm("Pop Code:" + value1 + "\n" + "Amount:" + form.amount.value + "\n" + "Updated Balance:" + balance + "\nPlease confirm!");
   if( retVal == true )
   {
      alert("User wants to continue!");
      return true;
   }else{
      alert("User does not want to continue!");
      return false;
   }
}
//-->
</script>

first call the function from your button code just like this

echo "<td><input type="image" src="images/update.png" onclick="getConfirmation('".$row1['pop_code']."');" alt="Update Row" class="update" title="Update Row"></td>";

when we define the function parameter the there is no need to declare variable as using var keyword so after that replace your javascript function declaration

<script type="text/javascript">
function getConfirmation(value1)
{

   var retVal = confirm("Pop Code:" + value1 + "\n" + "Amount:" + "" + "\n" + "Updated Balance:" + "" + "\nPlease confirm!");
   if( retVal == true )
   {
      alert("User wants to continue!");
      return true;
   }else{
      alert("User does not want to continue!");
      return false;
   }
}

</script>

我认为代码有两个问题。

  1. var从函数中删除
    function getConfirmation(value1)

  2. 该代码onclick=\"getConfirmation(".$row1['pop_code'].");\"将在 $row1['pop_code') 的整数值上创建正确的代码，即 getConfirmation(10)，但是当代码是文本时，它将是不正确的 getConfirmation(test)。所以你必须添加引用值。
    IEonclick=\"getConfirmation('".$row1['pop_code']."');\"

尝试改变

function getConfirmation(var value1)

至

function getConfirmation(value1)

您不能将var关键字用作函数参数。

尝试这个

function getConfirmation(value1){

  //Your function

}
