Question

我在这里尝试了很多例子，但我可以让我的代码在删除之前显示一个弹出窗口。我使用的代码可以在这里找到：

Answer 1

您只需对链接或按钮使用onclick方法：

<a href="DELETE_PAGE" onClick="return confirm('Delete This account?')">Delete Account</a>

Answer 2

  <script type="text/javascript">
      function ConfirmDelete()
      {
            if (confirm("Delete Account?"))
                 location.href='linktoaccountdeletion';
      }
  </script>


  echo '<input type="button" onclick="ConfirmDelete()" value="DELETE ACCOUNT">';

Answer 3

试试这个

 <form action="url/to/delation_page" onSubmit="return confirm('are you sure?')">

</form>

Answer 4

说完

onclick="return confirm('Are you sure you want to delete?')"
         ^^^^^^ --> this is very important step...

Answer 5

javascript确认

function doConfirm(id)
        {

            var ok = confirm("Are you sure to Delete?")
            if (ok)
            {

                if (window.XMLHttpRequest)
                {// code for IE7+, Firefox, Chrome, Opera, Safari
                    xmlhttp = new XMLHttpRequest();
                }
                else
                {// code for IE6, IE5
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
                }

                xmlhttp.onreadystatechange = function()
                {
                    if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
                    {
                         window.location = "create_dealer.php";  // self page
                    }
                }

                xmlhttp.open("GET", "delete_dealer.php?id=" + id);
                xmlhttp.send();
            }
        }

删除按钮

<input type="button" onclick="doConfirm();"/>

Answer 6

如果你使用on-click，数据将被删除但是要查看结果你必须手动刷新页面而不是使用 onSubmit =“返回确认（'你确定吗？'）”

认为这有帮助！

JavaScript在使用PHP / MYSQL删除之前确认
