JavaScript 在 AJAX 响应中不起作用

Question

下面的代码是对另一个页面的 AJAX 响应。我已将 onclick 事件添加到表行并编写 JavaScript 代码来处理它。但是javascript代码不起作用。这是编码方式错误还是代码有问题。建议我一个简单的解决方案

<?php

echo '<script type=\"text/javascript\">
    function clicked(){
      alert("I am an alert box!");
    }
    </script>';
$q = $_GET['q'];
include 'db_connect.php';
$sql="SELECT name,address,mobile,email,pan,tan FROM client WHERE name = '$q'";
$sql_bill="SELECT clientname,financialyear,receiptno,amount,ddate,type,chequeno,category FROM billing WHERE clientname = '$q'";
$sql_total="SELECT SUM(amount) AS TotalAmount FROM billing";
$result = mysql_query($sql);

$result_bill = mysql_query($sql_bill);
$result_total = mysql_query($sql_total);
$total= mysql_fetch_array($result_total);
echo "<h4><b>Client details</b></h4><table align='center' border='2'>
    <tr>
        <th>Name</th>
        <th>Address</th>
        <th>Mobile</th>
        <th>Email</th>
        <th>PAN</th>
        <th>VAT TIN</th>
    </tr>";

while($row = mysql_fetch_array($result))
{
  echo "<tr>";
  echo "<td>" . $row['name'] . "</td>";
  echo "<td>" . $row['address'] . "</td>";
  echo "<td>" . $row['mobile'] . "</td>";
  echo "<td>" . $row['email'] . "</td>";
  echo "<td>" . $row['pan'] . "</td>";
  echo "<td>" . $row['tan'] . "</td>";
  echo "</tr>";
}
echo "</table>";
echo "<h4><b>Payment received details</b></h4><table align='center' border='2'>
    <tr>
        <th>Client Name</th>
        <th>Financial Year</th>
        <th>Receipt No</th>
        <th>Date</th>
        <th>Type</th>
        <th>Chequeno</th>
        <th>Category</th>
        <th>Amount</th>
    </tr>";

while($row = mysql_fetch_array($result_bill))
{
  echo "<tr onclick=\"clicked()\">";
  echo "<td>" . $row['clientname'] . "</td>";
  echo "<td>" . $row['financialyear'] . "</td>";
  echo "<td>" . $row['receiptno'] . "</td>";
  echo "<td>" . $row['ddate'] . "</td>";
  echo "<td>" . $row['type'] . "</td>";
  echo "<td>" . $row['chequeno'] . "</td>";
  echo "<td>" . $row['category'] . "</td>";
  echo "<td>" . $row['amount'] . "</td>";
  echo "</tr>";
}

echo "<tr>";
echo "<td colspan=7>Total</td>";
echo "<td>".$total['TotalAmount'].  "</td>";
echo "</tr>";

echo "</table>";

?>

试试这个而不是你的脚本代码:

echo <<<EOD
  <script type="text/javascript">
    function clicked(){
      alert("I am an alert box!");
    }
  </script>
EOD;
