Title: jQuery Tips: Dynamically Insert New Rows into Tables
In web development, it is often necessary to dynamically insert new rows into tables. This function It's very easy to achieve using jQuery. The following will introduce how to use jQuery to dynamically insert new rows into the table, and provide specific code examples.
First, make sure the jQuery library is introduced in the HTML file, either through a CDN link or a local file. The following is a simple HTML structure, containing a table and a button:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>动态在表格中插入新的行</title> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> </head> <body> <table id="myTable"> <tr> <th>Name</th> <th>Age</th> </tr> </table> <button id="addRowBtn">新增行</button> </body> </html>
Next, we need to write jQuery code to insert a new row in the table when the button is clicked. The code is as follows:
$(document).ready(function() {
$('#addRowBtn').click(function() {
var name = prompt('请输入姓名：');
var age = prompt('请输入年龄：');
var newRow = '<tr><td>' + name + '</td><td>' + age + '</td></tr>';
$('#myTable').append(newRow);
});
});In the above code, we first bind the click event of the button after the document is loaded. When the button is clicked, two prompt boxes pop up to enter your name and age respectively, and HTML code that concatenates the entered values into a new table row. Finally, use jQuery's append() method to insert the new row into the table.
Now, we have completed the function of dynamically inserting new rows in the table. You can copy and paste the above HTML and jQuery code into an HTML file, open it in the browser, and click the button to test the effect. Through this example, I hope it can help you learn how to use jQuery to dynamically insert new rows into a table.

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AMThe main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.
Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AMWhether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.
Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AMPython and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.
