HTML 可编辑表：添加新行，包括单选按钮
比方说，我有一个可编辑的 html 表格。在这些表格单元之一中，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，当页面最初加载表格时，类似于：
<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>
您可以看到第一列有带有group1组名的单选按钮。
我想说的是，下次当我单击添加新行按钮时，新行应该
包括具有新组名称组 2、组 3 的相同单选按钮 .... 并且应检查第一个单选选项
并且其他td （表数据）应该是 contenteditable ，其中没有值：
<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）交互后向文档对象模型 (DOM) 添加新对象，可能需要一些 JavaScript。请参阅以下小提琴：在纯 JavaScript 中：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<button onclick="AddRow()">Add row</button>向您的 DOM添加了一个（在 HTML 中），并添加了一个带有该函数的脚本Addrow()（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> <td contenteditable></td> <td contenteditable></td> <td contenteditable></td> <td contenteditable></td> <td contenteditable></td> <td contenteditable></td> </tr> </tbody></table><button id="row-button">Add row</button> -
