Question

我正在asp.net中开发Web应用程序。我的要求是在每个按钮点击事件（如插入，更新和删除按钮）上显示确认消息。我正在使用jQuery消息框通过应用程序成功插入，更新和删除。

let domainName = NSBundle.mainBundle().bundleIdentifier!       
NSUserDefaults.standardUserDefaults().removePersistentDomainForName(domainName)

调用按钮点击事件

    function MessageBox(Title, InnerText) {
    try {
        var dialog = $('<p class="messagebox">' + InnerText + '</p>').dialog({
            title: Title,
            width: "240",
            modal: true,
            buttons: {
                "OK": function () {
                    dialog.dialog('close');
                }
            }
        });
    }
    catch (e) {
        MessageBox('Tracker Alert', e);
    }
}

然后，如何使用与上述功能相同的jQuery消息框在按钮点击事件上显示确认消息？

  <script type="text/javascript">
      $(window).on('mouseover', (function () {
          window.onbeforeunload = ConfirmLeave;
      }));
      $(window).on('mouseout', (function () {
          window.onbeforeunload = ConfirmLeave;
      }));
      function ConfirmLeave() {         
          return "";
      }
 var prevKey = "";
  $(document).keydown(function (e) {
      if (e.key == "F5") {
          window.onbeforeunload = ConfirmLeave;
      }
      else if (e.key.toUpperCase() == "W" && prevKey == "CONTROL") {
          window.onbeforeunload = ConfirmLeave;
      }
      else if (e.key.toUpperCase() == "R" && prevKey == "CONTROL") {
          window.onbeforeunload = ConfirmLeave;
      }
      else if (e.key.toUpperCase() == "F4" && (prevKey == "ALT" || prevKey == "CONTROL")) {
          window.onbeforeunload = ConfirmLeave;
      }
      prevKey = e.key.toUpperCase();
  });
</script>
