        $tablename=$_GET['table'];
        $return=$_GET['return'];




        if($tablename=="labour_details")
        {
                    $sql=mysql_query("SELECT * FROM `labour_details` WHERE `id`='$id'");
                    $row_1=mysql_fetch_array($sql);

                    if($labour_name!="")
                    {
                        $str=mysql_query("DELETE FROM `labour_details` WHERE `id`='$id'");
                        if($str)
                        {
                            header("location:$return?msg=Record Deleted Successfully!&id=$id");
                        }else{
                            echo "Problem in deleting :";
                        }
                    }

        }

}

我的问题是在哪里添加提醒，以便在删除记录之前显示javascript按钮如果允许那么它将删除记录。

function confirmSubmit()
{
    var agree=confirm("Are you sure you wish to Delete this Entry?");
    if (agree)
        return true ;
    else
        return false ;
}

Answer 1

此行将在重定向之前显示确认对话框。

<a onclick="return confirm('Are You sure?')">...</a>

Answer 2

首先，您需要创建confirmSubmit（）函数

<script>
function confirmSubmit()
{
    if (confirm('Are you sure you want to delete this?'))
    {
        return true;
    }
    return false;
}
</script>

然后你将它附加到你的A标签上，就像你做的那样..

<a href="..." onclick="return confirmSubmit();">blah</a>

Answer 3

您可能正在寻找confirm。

然后，confirmSubmit函数的主体看起来像：

function confirmSubmit() {
    return confirm ("Are you sure you want to do this?");    
}

这可以归功于事件处理程序在javascript中的工作方式。当用户单击“确定”时确认返回true，单击“取消”时返回false。

通过从事件处理函数返回true / false值，您可以告诉窗口是否继续处理该事件。返回false（当用户点击取消时发生）告诉浏览器停止处理该事件而不是关注该链接。

Answer 4

<td width="100"><a onclick="confirmSubmit(id)"><img src="../images/delete.png" border="0" alt="delete"></a></td>




function confirmSubmit(delete_id)
{
var r=confirm("Are you sure you want to delete?");

if(r==true)
{
         window.location.href = "delete.php?id="+delete_id"; ?>&table=labour_details&return=content_display.php"
    }
}

<a onclick="return confirm('Are you sure?')" href="delete.php">delete</a>
