Introduction to how to add new rows to a table using jQuery

jQuery is a popular JavaScript library that is widely used in web development. During web development, it is often necessary to dynamically add new rows to tables through JavaScript. This article will introduce how to use jQuery to add new rows to a table, and provide specific code examples.

First, we need to introduce the jQuery library into the HTML page. The jQuery library can be introduced in the

tag through the following code:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

Next, we assume there is a table with the id "myTable" and the structure is as follows:

<table id="myTable">
  <tr>
    <td>姓名</td>
    <td>年龄</td>
  </tr>
  <tr>
    <td>张三</td>
    <td>25</td>
  </tr>
  <tr>
    <td>李四</td>
    <td>30</td>
  </tr>
</table>

Now, We want to add new rows to this table via jQuery. Here is a code example using jQuery:

// 创建一个新的<tr>元素
var newRow = $('<tr>');

// 为新行添加<td>元素和内容
newRow.append('<td>王五</td>');
newRow.append('<td>28</td>');

// 将新行添加到表格中
$('#myTable').append(newRow);

The above code first creates a new <tr> element and then appends it to the new row via the <code>append() method Add <td> elements and content, and finally add new rows to the table with id "myTable". <p>Through the above code example, we can implement the function of adding new rows to the table using jQuery. Adding new rows not only dynamically displays data, but also improves user experience. I hope this article was helpful and I wish you success in web development! </p> </td>
