我已经在某个函数上坐了很长时间了.经过大量的研究和测试，我还没有想出一个最终的解决方案.

编辑=在下拉 Select 后显示字段
确认=使字段再次消失，并覆盖在相应单元格中字段中写入的内容，但前提是在此键入了内容
如何在相应的表格单元格中手动插入输入字段
<script>
function createInputFields() {
var row1 = document.getElementById("tableLKW").rows[1].cells;
var row2 = document.getElementById("tableLKW").rows[2].cells;
row1[0].innerHTML = "<input type='text' class='newInputBoxRow1'>";
row1[1].innerHTML = "<input type='text' class='newInputBoxRow1'>";
row2[0].innerHTML = "<input type='text' class='newInputBoxRow2'>";
}
</script>
<button onclick="createInputFields()"></button>我的表(用bootstrap装饰)和下拉 Select 看起来像这样.

<label for="table-rows">Choose a table row:</label>
<select name="table-rows" id="table-row">
<option value="row1" id="choice1">Table Row 1</option>
<option value="row2" id="choice2">Table Row 2</option>
<option value="row3" id="choice3">Table Row 3</option>
<option value="row4" id="choice4">Table Row 4</option>
</select>我知道这是通过if/else查询实现的，只是我不知道如何将下拉菜单中的 Select 与确认按钮和if结合起来
这应该是什么样子的一些屏幕截图(可视化).
