中的可编辑表格

以上可编辑字段对我来说非常适合但我正在尝试克隆此表我无法正确导出数据，这里是代码

var $TABLE = $('#table');
var $BTN = $('#export-btn');
var $EXPORT = $('#export');

$('.table-add').click(function () {
  var $clone = $TABLE.find('tr.hide').clone(true).removeClass('hide table-line');
  $TABLE.find('table').append($clone);
});

$('.table-remove').click(function () {
  $(this).parents('tr').detach();
});

$('.table-up').click(function () {
  var $row = $(this).parents('tr');
  if ($row.index() === 1) return; // Don't go above the header
  $row.prev().before($row.get(0));
});

$('.table-down').click(function () {
  var $row = $(this).parents('tr');
  $row.next().after($row.get(0));
});

// A few jQuery helpers for exporting only
jQuery.fn.pop = [].pop;
jQuery.fn.shift = [].shift;

$BTN.click(function () {
  var $rows = $TABLE.find('tr:not(:hidden)');
  var headers = [];
  var data = [];
  
  // Get the headers (add special header logic here)
  $($rows.shift()).find('th:not(:empty)').each(function () {
    headers.push($(this).text().toLowerCase());
  });
  
  // Turn all existing rows into a loopable array
  $rows.each(function () {
    var $td = $(this).find('td');
    var h = {};
    
    // Use the headers from earlier to name our hash keys
    headers.forEach(function (header, i) {
      h[header] = $td.eq(i).text();   
    });
    
    data.push(h);
  });
  
  // Output the result
  $EXPORT.text(JSON.stringify(data));
});

现在问题出现了，我无法区分哪个克隆的部分数据即将到来我需要通过php处理所有数据并将其正确存储在数据库中

Answer 1

您的问题与标记中的重复ID有关。请记住，ID必须是唯一的。话虽如此，您需要稍微更新您的JS以考虑所选的适当元素。

查看使用.parent()，。parents()等遍历DOM，并记住this所指的内容。如果你需要的话，我可以帮你解决一下。
