Question

比方说，我有一个可编辑的html表。在这些表单元格之一中，它包含单选按钮。我想要的是添加一个新的行按钮。当我单击按钮时，新行应包含与新组相同的单选按钮。

比方说，页面最初加载表时，就像这样：

<table id="exp02Table" class="responsive-table">
  <thead>
    <tr class="bengaliText">
      <th> (P)</th>
      <th> (a cm)</th>
      <th> (b cm)</th>
      <th> (c cm)</th>
      <th> L=(a-b) cm</th>
      <th> H = (c-b) cm </th>
      <th> P = H±h</th>
      <th> PV = (H±h)*L</th>
    </tr>
  </thead>
  <tbody id="exp02TBody">
    <tr>
      <td>
        <p> <label> <input value="0" checked name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপ</span> </label> </p>
        <p> <label> <input value="1" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের বেশী</span> </label> </p>
        <p> <label> <input value="2" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের কম</span> </label> </p>
      </td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
    </tr>
  </tbody>
</table>

您可以看到第一列具有带有 group1 组名称的单选按钮。

我要说的是，下次单击添加新行按钮时，新行应该

包括与新的组名称组2，组3 ...相同的单选按钮，并且应选中第一个单选选项

和其他 td（表数据）应该是内容可编辑的，没有值：

<tr>
  <td>
    <p> <label> <input value="0" checked name="group2" type="radio" /> <span>বায়ু মন্ডলের চাপ</span> </label> </p>
    <p> <label> <input value="1" name="group2" type="radio" /> <span>বায়ু মন্ডলের চাপের বেশী</span> </label> </p>
    <p> <label> <input value="2" name="group2" type="radio" /> <span>বায়ু মন্ডলের চাপের কম</span> </label> </p>
  </td>
  <td contenteditable></td>
  <td contenteditable></td>
  <td contenteditable></td>
  <td contenteditable></td>
  <td contenteditable></td>
  <td contenteditable></td>
  <td contenteditable></td>
</tr>

为了在与某种元素（例如按钮）交互之后向您的文档对象模型（DOM）添加新对象，可能需要一些JavaScript。请参见以下小提琴：

使用普通JavaScript：

let i = 1;
function AddRow() {
  i++;
  let tbody = document.getElementById("exp02TBody");
  let tr = document.createElement("tr");
  
  //The HTML for the row. Obviously not as readable in JavaScript so there might a bit cleaner solution to this but at least it's functional:
  tr.innerHTML =
    "<td><p><label><input value='0' checked name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপ</label></p><p><label><input value='1' name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপের বেশী</label></p><p><label><input value='2' name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপের কম</label></p></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td>";
    
  tbody.appendChild(tr);
}

<table id="exp02Table" class="responsive-table">
  <thead>
    <tr class="bengaliText">
      <th> (P)</th>
      <th> (a cm)</th>
      <th> (b cm)</th>
      <th> (c cm)</th>
      <th> L=(a-b) cm</th>
      <th> H = (c-b) cm </th>
      <th> P = H±h</th>
      <th> PV = (H±h)*L</th>
    </tr>
  </thead>
  <tbody id="exp02TBody">
    <tr>
      <td>
        <p> <label> <input value="0" checked name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপ</span> </label> </p>
        <p> <label> <input value="1" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের বেশী</span> </label> </p>
        <p> <label> <input value="2" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের কম</span> </label> </p>
      </td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
      <td contenteditable></td>
    </tr>
  </tbody>
</table>
<button onclick="AddRow()">Add row</button>

我在您的DOM中添加了<button onclick="AddRow()">Add row</button>（在HTML中），并添加了一个带有功能Addrow()的脚本（请参阅小提琴以获取参考）。

在jQuery中：

$(document).ready(function() {
  let i = 1;
  $("#row-button").on("click", function() {
    i++;
    $("#exp02TBody").append("<tr><td><p><label><input value='0' checked name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপ</label></p><p><label><input value='1' name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপের বেশী</label></p><p><label><input value='2' name='group-" + i + "' type='radio'> বায়ু মন্ডলের চাপের কম</label></p></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td><td contenteditable></td></tr>");
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="exp02Table" class="responsive-table">
  <thead>
    <tr class="bengaliText">
      <th> (P)</th>
      <th> (a cm)</th>
      <th> (b cm)</th>
      <th> (c cm)</th>
      <th> L=(a-b) cm</th>
      <th> H = (c-b) cm </th>
      <th> P = H±h</th>
      <th> PV = (H±h)*L</th>
    </tr>
  </thead>
  <tbody id="exp02TBody">
    <tr>
      <td>
        <p> <label> <input value="0" checked name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপ</span> </label> </p>
        <p> <label> <input value="1" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের বেশী</span> </label> </p>
        <p> <label> <input value="2" name="group1" type="radio" /> <span>বায়ু মন্ডলের চাপের কম</span> </label> </p>
      </td>

      <td contenteditable></td>
