请查看修改后的 HTML 和 JS 代码。希望它对您有用:

var cc = 1;

CalculateGrandTotal();


	function addTableRow(jQtable){
		var id=cc;
		jQtable.each(function() {
			var data = "<tr><td class='Arial_4C8966' align='center'><input name='InvoiceDate[]' type='date' class='form-control'  placeholder='' style='width:160px'  id='InvoiceDate_" + cc + "' size='10'  onclick='showData(this.value," + cc + ")'/></td><td class='Arial_4C8966'><input name='Details[]' type='text'  class='form-control' style='width:240px'  id='Details_" + cc + "' size='10'/></td><td class='Arial_4C8966'><input name='ReceiptNo[]' type='text'  class='form-control' style='width:180px' id='ReceiptNo_" + cc + "' size='10' /></td><td class='Arial_4C8966'><input name='Amount[]' class='form-control'  style='width:180px' type='text'   onblur='copy_data(this);' id='Amount_" + cc + "' size='10'   /></td><td class='Arial_4C8966'><input name='Total[]' style='width:180px'  class='form-control Total'  type='text' id='Total_" + cc + "' size='10' /></td><td class='Arial_4C8966'><img src='assets/img/pictures.png' style='cursor:pointer; border:0px; width:16px;' onclick='setDeletedID("+ cc +");$(this).parent().parent().remove();' />";
			var $table = $(this);
			var n = $('tr:last td', this).length;

			cc++;

			}
		});
	}
    function copy_data(obj){
	   var current = $(obj);
	   var currentTr = current.closest("tr");
	   var currentTotalElem = currentTr.find(".Total");
	   currentTotalElem.val(current.val());
      
       CalculateGrandTotal();
	}
	
//calculate the grand total
    function CalculateGrandTotal(){
      var grandTotal = 0;
      $(".Total").each(function(){
        var currVal = $(this).val();
        if(!isNaN(currVal))

请尝试按原样使用上述 JS 和 HTML 代码。将您对应的代码替换为上面的代码。请注意:如果 HTML 不包含任何带有 id txtDeletedIDs 的元素，您的 function setDeletedID 将不起作用。请再检查一下。谢谢。
