改进user1697128(因为我还不能评论它)

<script>
    function ConfirmDelete()
    {
      return confirm("Are you sure you want to delete?");
    }
</script>    
    
<button Onclick="return ConfirmDelete();" type="submit" name="actiondelete" value="1"><img src="images/action_delete.png" alt="Delete"></button>

如果按“取消”键，会取消提交表格吗

您可以更好地使用以下方法

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>

function del_confirm(msg,url)
        {
            if(confirm(msg))
            {
                window.location.href=url
            }
            else
            {
                false;
            }

        }



<a  onclick="del_confirm('Are you Sure want to delete this record?','<filename>.php?action=delete&id=<?<id> >')"href="#"></a>

试试这个。这对我很有用

 <a href="delete_methode_link" onclick="return confirm('Are you sure you want to Remove?');">Remove</a>

<form onsubmit="return confirm('Are you sure?');" />

适用于表单。表单特定的问题:JavaScript表单提交-确认或取消提交对话框
