在删除数据之前弹出消息窗口

Question

我正在尝试在用户删除数据之前，在此代码中放置弹出消息。这是我的代码。

while ($test = mysql_fetch_array($result))
{
    $id = $test['FailID'];

    echo "<tr align='center'>"; 
    echo"<td><font color='black'>" .$test['FailID']."</font></td>";
    echo"<td><font color='black'>" .$test['TajukFail']."</font></td>";
    echo"<td><font color='black'>". $test['JilidFail']. "</font></td>";
    echo"<td><font color='black'>". $test['StatusFail']. "</font></td>";    
    echo"<td> <a href ='daftarkemaskini.php?FailID=$id'>Edit</a>";
    echo"<td> <a href ='padamfail.php?FailID=$id'><center>Delete</center></a>";

    echo "</tr>";
}

但是当我把它放在那里时，它根本不能工作。

echo"<td> <a href ='padamfail.php?FailID=$id' onClick="return confirm('are you sure you want to delete??');"><center>Delete</center></";>"

有人能帮我解决这个问题吗？

Answer 1

你需要转义双引号。你的代码还有一个语法错误在结尾处。

echo "<td> <a href='padamfail.php?FailID=$id' onClick=\"return 
confirm('are you sure you want to delete??');\"><center>Delete</center></a>";

Answer 2

您正在将JavaScript onclick代码放在双引号中，而这些双引号被用于终止echo。请转义这些双引号：

echo"<td> <a href ='padamfail.php?FailID=$id' onClick=\"return confirm('are you sure you want to delete??');\"><center>Delete</center></a>"

你可以试试这个 -

echo "<td> <a href ='padamfail.php?FailID=$id' onClick=return confirm('are you sure you want to delete??');><center>Delete</center></;>";

请将该行更改为：

 echo"<td> <a href ='padamfail.php?FailID=$id' onClick="return confirm('are you sure you want to delete??');"><center>Delete</center></";>"

到

echo "<td> <a href ='padamfail.php?FailID=$id' onClick='return confirm('are you sure you want to delete??');' ><center>Delete</center></a>";

<div class="third">
<input type="button" value="Remove" class="remve" name="<?php echo $row['choice_id']; ?>" onClick="deleteImage(<?php echo $row['choice_id']; ?>)"style="cursor:pointer;">
</div>


<script type="text/javascript">
function deleteImage(x){
var conf = confirm("Are you sure you want to delete this choice?");
if(conf == true){
window.location = "addnewentry/choiceRemove.php?id="+x;
}
}
</script>

尝试转义字符串：

echo "<td> <a href ='padamfail.php?FailID=$id' onClick=\"return confirm('are you sure you want to delete??');\"><center>Delete</center></";>"

Answer 7

echo"<td><a href='delete.php?id={$row['id']}' onclick='return confirm_alert(this);' >Delete</a></td>"; **你应该尝试这段代码，它一定会起作用的**

=

<script>

//alert on delete

function confirm_alert(node) {

    return confirm("You are about to permanently delete a product. Click OK to continue or CANCEL to quit.");

}

</script>

<script>

//alert on delete

function confirm_alert(node) {

    return confirm("You are about to permanently delete a product. Click OK to continue or CANCEL to quit.");

}

</script>

希望这能对你有所帮助
