Use jQuery to generate dynamic tables with row numbers

jQuery Tips: Dynamically generate tables and automatically increase row numbers

In web development, it is often necessary to dynamically generate tables to display data. At the same time, in order to make it easier for users to view the table content, we often need to add row numbers to the table. This article will introduce how to use jQuery to dynamically generate tables and automatically increase row numbers.

First, we need a simple HTML structure, including a button to trigger the action of dynamically generating a table, and an empty

element to place the generated table.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Dynamic Table with Row Numbers</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
    <button id="generateTable">生成表格</button>
    <div id="tableContainer"></div>

    <script>
        // jQuery代码将会在下文中给出
    </script>
</body>
</html>

Copy after login

Next, we use jQuery to write code to dynamically generate tables and automatically increase row numbers. The code is as follows:

$(document).ready(function() {
    $('#generateTable').click(function() {
        var tableHtml = '<table border="1">';
        for (var i = 0; i < 5; i++) { // 生成5行表格，实际应用中可以根据需求动态设置行数
            tableHtml += '<tr><td>' + (i + 1) + '</td><td>数据列1</td><td>数据列2</td></tr>';
        }
        tableHtml += '</table>';

        $('#tableContainer').html(tableHtml);
    });
});

Copy after login

In the above code, we use jQuery’s $(document).ready() function to ensure that the page is loaded before executing the code. When the button is clicked, a click event is triggered, a table containing 5 rows is generated, and a row number is added to each row. In actual applications, more complex content and styles can be added to the table as needed.

Through the above code, we have realized the function of dynamically generating tables and automatically adding row numbers. This technique can help us display data more conveniently and make it easier for users to read and understand table contents. I hope that through the introduction of this article, readers can flexibly use this technique in their own projects to improve user experience.
