Question

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

它应该是这样的：

行数是动态的，我可以使用Array生成它。我将所有值捕获到每行的记录数组中并将其推入表中。但我不知道如何添加空文本框。

我在想是否可以添加＆＃34;文本框＆＃34;到数组并与文本一起插入表格单元格。我不确定还有其他选择。

我愿意回答您的任何问题，这可能有助于我得到答案。

修改：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2D数组。数组中的每个元素都包含一行表的所有数据。下一个数组元素包含下一行的数据。我想在每行中插入文本框。 TIA

我认为这将是您动态创建记录的答案。
