javascript - 将文本框连同文本添加到 HTML 中的表格 (tbody)

我遇到了一个问题，我必须在表格单元格中动态创建文本框。以及我从数据库中获取的数据。

它应该是这样的: enter image description here

行数是动态的，我可以使用数组生成它。我将所有值捕获到每一行的记录数组中，并将其插入表中。但我不知道如何添加空文本框。

我在想是否可以将“文本框”添加到数组中并与文本一起插入到表格单元格中。我不确定还有哪些其他选项可用。

我愿意回答任何可能帮助我得到答案的问题。

编辑:下面是我用来生成表格的代码:

function generateTable(fundDetails){
  var tbody_holder = document.getElementById("tbody_holder");
  for(var row = 0; row < fundDetails.length; row++){
    var tr = document.createElement("tr");
    for(var col = 0; col < fundDetails[row].length; col++){
      var td = document.createElement("td");
      var tn = document.createTextNode(fundDetails[row][col]);
      td.appendChild(tn);
      tr.appendChild(td);
    }
  tbody_holder.appendChild(tr);
 }
}

fundDetail 是一个二维数组。数组中的每个元素都包含表格一行的所有数据。下一个数组元素包含下一行的数据。我想在每一行中插入文本框。时间差

最佳答案

我认为这将是您动态创建记录的答案。
