Question

我有一个动态HTML表格，可以通过多种方式进行编辑。有一个编辑按钮，您可以在其中编辑内联，行的信息，然后单击保存以保存信息。用于灰显行的停用按钮和随后显示的激活按钮，以便重新激活它。并且还添加了一个行按钮，弹出一个对话框，您可以在其中再次点击添加行并向表中添加另一行。

然而，虽然这一切都很好......我想现在将这些更改/更新写入SQL Server数据库，以便实际保存它们。我希望能够在每个操作（保存，停用/激活和添加行）发生后自动保存这些更改。我之前从未这样做过，所以任何帮助/建议/代码都会受到赞赏！

JavaScript代码：

// ----- Deactivate/Activate Row -----

$(document).on("click", "#html_master .deactivate", function () {
  var $this = $(this);
  var $tr = $this.closest('tr');
  var action = $tr.hasClass('deactivated') ? 'activate' : 'deactivate';

  // ------ Confirmation box in order to deactivate/activate row -----
  if (confirm('Are you sure you want to ' + action + ' this entry?')) {
    $tr.toggleClass('deactivated');
    $this.val(function (i, t) {
      return t == 'Deactivate' ? 'Activate' : 'Deactivate';
    });
  }
});

// ----- Edit Row -----

$(document).on("click", "#html_master .edit", function () {
  var $this = $(this);
  var tds = $this.closest('tr').find('td').not('.mr_id').filter(function () {
    return $(this).find('.edit').length === 0;
  });
  if ($this.val() === 'Edit') {
    $this.val('Save');
    tds.prop('contenteditable', true);
  } else {
    var isValid = true;
    var errors = '';
    $('#myDialogBox').empty();
    // changed from here.......
    var elements = tds;
    if (tds.find('input').length > 0) {
      elements = tds.find('input');
    }
    elements.each(function (index, element) {
      var type = $(this).attr('class');
      var value = (element.tagName == 'INPUT') ? $(this).val() : $(this).text();
      // changed from here....... to here
      // ----- Switch statement that provides validation -----
      switch (type) {
        case "buyer_id":
          if (!$.isNumeric(value)) {
            isValid = false;
            errors += "Please enter a valid Buyer ID\n";
          }
          break;
        case "poc_n":
          if (value == value.match(/^[a-zA-Z\s]+$/)) {
            break;

没有Ajax - 这可以通过（PHP / ASP）＆＃39;传递＆＃39;来完成。 window.open - 这是一个打开的窗口，它处理传递的参数并将它们写入SQL数据库然后自行关闭。这使原始站点保持不变，但会根据您的更改更新数据库。

所以，window.open（saveChanges.php？param1 = ..＆amp; param2 = ..＆amp; etc，....）

saveChanges.php文件应该在传递的参数中读取并运行相应的SQL来保存更新。

完成后，saveChanges.php文件应该通过window.close（）

关闭

您的数据库现在应该反映您网页条目的内容。
