刪除表中的行之前顯示一個確認框

Question

我有一個表，它的觀點是這樣的

ID NAME LOCATION DELETE 
1 sam US  delete 

我有一個刪除給定行

echo "<td><a href=\"delete_members.php?id=".$row['id']."\">Delete</a></td>"; 

表的語句它重定向到delete_members.php頁面，行被刪除，但我希望顯示一個警告框，以確保用戶想要刪除該行。它我有一個代號爲delete_members.php頁面

<?php 
include('admin_session.php'); 
$con=mysqli_connect("abc.com","abc","abc","abc"); 
// Check connection 
if (mysqli_connect_errno()) { 
echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
} 

$id = $_GET['id']; 

mysqli_query($con,"DELETE FROM members WHERE id='".$id."'"); 
mysqli_close($con); 
header("Location: admin_member_list.php"); 
?> 

然而

<button onclick="myFunction()">Delete</button> 

<script> 
function myFunction() { 
    var x; 
    if (confirm("Press a button!") == true) { 
     window.location="yourphppage.php"; // not sure which link should be placed here 
     return true; 
    } else { 
     window.location="index.php"; 
     return true; 
    } 
    document.getElementById("demo").innerHTML = x; 
} 
</script> 

代碼，我無法以適當的方式與語句中使用的確認腳本。我希望在點擊上面給出的第一個語句中存在的編輯按鈕後彈出警告框（即腳本運行），然後如果用戶確認它應該運行delete_members.php腳本。希望如果有人能指導我

Answer 1

在最簡單的方法：

echo "<a onclick=\"return confirm('Delete this record?')\" href=\"delete_members.php?id=".$row['id']."\">delete</a>"; 

你也可以做到這一點不顯眼的方式，通過一次使用類似添加類的鏈接並選擇他們所有jQuery，然後將確認邏輯綁定到onclick事件。事情是這樣的：

$('a.delete').on('click', function() { 
    var choice = confirm('Do you really want to delete this record?'); 
    if(choice === true) { 
     return true; 
    } 
    return false; 
}); 

Answer 2

echo "<a href='delete_members.php?id={$row['id']}' onclick=\"return confirm('Do you really want to delete this?')\">DELETE</a>"; 

Answer 3

你可以試試這個。希望它能爲你工作..

添加一個'刪除'類到錨標記。

echo "<td><a href=\"delete_members.php?id=".$row['id']."\" class=\"delete\">Delete</a></td>"; 

然後綁定刪除功能：

$('.delete').on('click', myFunction); 

Answer 4

我認爲這將是有用的，請看看這個

的$ id = $行[ '身份證'];

如果你想通過編號可以使用$ ID，否則只是調用功能，無需PARAMS

echo "<a href='#' onclick='deletemember($id)'>Delete</a>"; 

<script> 

    function deletemember(id) 
     { 
       var r = confirm("Are you sure you want to delete"); 
       if(r == true) 
       { 
        $.ajax({ 
           type:"GET", 
           url:"delete_members.php", 
           data: ({id:id}), 
           success: function(data) 
           { 
            window.location="yourphppage.php"; 
           } 
         }); 

       } 
       else 
       { 
        window.location="index.php";   
       } 
    } 

</script>
