显示对话框以向HTML表添加新行

标签： javascript jquery html dialog html-table

所以我目前有一个HTML表格，我可以在表格的末尾添加行。出现一个新行，其中包含文本框，您可以输入信息。

但是，我想要废除它并使用新方法。我想要它，以便在单击add row按钮时弹出dialog box并为我提供添加行信息的选项。然后它使用validation来确保行好，然后将行添加到表中。

我怎么能这样做？

你可以看到演示......

JavaScript的：

// ----- 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;

您可以使用模态弹出窗口。看看它：How to create a modal popup using javascript

您必须在该模态上创建单独的div，将所有必需的输入字段放在该子div中。

您需要做的就是触发弹出＆＃34;添加行＆＃34;按钮单击，获取用户输入，关闭弹出窗口，验证代码并将其注入表格。

我已经为你编写了这段代码，希望有所帮助
