Detailed explanation of the steps to insert new rows in the table using jQuery

In web development, jQuery can be used to easily operate DOM elements and achieve interactive effects on the page. Inserting new rows into tables is a common requirement. This article will introduce in detail how to use jQuery to achieve this function and provide specific code examples.

1. Introduce the jQuery library

Before using jQuery, you first need to introduce the jQuery library into the web page. It can be imported through CDN, or you can download the jQuery library locally and then import it.

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

2. Write HTML table structure

Write a simple table structure in the page to demonstrate the effect of inserting new rows in the table.

<table id="myTable">
    <thead>
        <tr>
            <th>姓名</th>
            <th>年龄</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>张三</td>
            <td>25</td>
        </tr>
        <tr>
            <td>李四</td>
            <td>30</td>
        </tr>
    </tbody>
</table>
<button id="addRow">添加新行</button>

3. Use jQuery to insert new rows

Next, we use jQuery to implement the function of inserting new rows into the table after clicking the button.

$(document).ready(function() {
    $('#addRow').click(function() {
        $('#myTable tbody').append(`
            <tr>
                <td>王五</td>
                <td>28</td>
            </tr>
        `);
    });
});

In the above code, we first use $(document).ready() to ensure that the page is loaded before executing the code. Then, listen to the button click event through $('#addRow').click(), and perform the corresponding operation when the button is clicked. In the click event handler, use $('#myTable tbody').append() to add a new row to the tbody of the table.

4. Integrate the code

Based on the above steps, integrate the code that introduces the jQuery library, the HTML code of the table structure and the JavaScript code that inserts new rows.

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


    

        

            

                
姓名
                
年龄
            
        
        

            

                
张三
                
25
            
            

                
李四
                
30
            
        
    
    添加新行
    
    <script>
        $(document).ready(function() {
            $('#addRow').click(function() {
                $('#myTable tbody').append(`
                    <tr>
                        <td>王五</td>
                        <td>28</td>
                    </tr>
                `);
            });
        });
    </script>

Conclusion

Through the above steps, we introduced in detail how to use jQuery to implement the function of inserting new rows in the table, and provided specific code examples. In this way, the effect of dynamically adding data to the table can be easily and quickly realized, improving the user experience.
