Question

我在HTML表格中添加/删除动态行。使用此代码，我可以动态添加和删除行。我想在第一行添加一个带有输入值的行，就像我输入'debasish'一样，它会追加值为'debasish'的下一行。但附加行空白值。如何使用输入值附加行？

<html>
<head>
<title>Add/Remove dynamic rows in HTML table</title>
<script>
        function addRow(tableID) {
            var table = document.getElementById(tableID);
            var rowCount = table.rows.length;
            var row = table.insertRow(rowCount);
            var colCount = table.rows[0].cells.length;
            for(var i=0; i<colCount; i++) {
                var newcell = row.insertCell(i);
                newcell.innerHTML = table.rows[1].cells[i].innerHTML;
                //alert(newcell.childNodes);
                switch(newcell.childNodes[0].type) {
                    case "text":
                            newcell.childNodes[0].value = "";
                            break;
                    case "checkbox":
                            newcell.childNodes[0].checked = false;

                var chkbox = row.cells[0].childNodes[0];
                if(null != chkbox && true == chkbox.checked) {
                    if(rowCount<=1) {
                        alert("Cannot delete all the rows.");
                        break;
                    }
                    table.deleteRow(i);
                    rowCount--;
                    i--;
                }
            }
            }catch(e) {

如果您只想从第一行的输入中获取值，请使用以下命令：

 case "text":
    newcell.childNodes[0].value = table.rows[1].cells[1].querySelector("input").value;
    break;

function addRow(tableID) {

  var rowCount = table.rows.length;
  var row = table.insertRow(rowCount);
  var colCount = table.rows[0].cells.length;
  for (var i = 0; i < colCount; i++) {
    var newcell = row.insertCell(i);
    newcell.innerHTML = table.rows[1].cells[i].innerHTML;
