该函数仅适用于表中的第一行，但在下一行中无法正常工作。有没有人能解决这个问题？提前谢谢

Answer 1

首先使用var rows = document.getElementById(tableId).getElementsByTagName("tr").length;获取表格中的行数然后使用for循环多次运行脚本。

Answer 2

您需要根据单击的按钮隔离每个行实例中的所有字段。

摆脱for()循环并执行以下操作：

$(".addSkip").click(function() {
  // row instance to use `find()` for the other input classes
  var $row = $(this).closest('tr');

  var date = new Date($row.find(".start_date").val()),
    days = parseInt($row.find(".days").val(), 10);

  if (!isNaN(date.getTime())) {
    date.setDate(date.getDate() + days);

    $row.find(".end_date").val(date.toInputFormat());
  } else {
    alert("Invalid Date");
  }
});
