Title: JQuery Tips: How to achieve alternating background colors of tables with alternate rows

In web development, tables are one of the commonly used elements, and it is often necessary to optimize the style of the tables. To improve the beauty and readability of the page. Among them, it is a common requirement to realize alternating background colors of tables on alternate rows. By alternating background colors, the table can be made clearer. In this article, we will introduce the method of using JQuery to realize alternating background colors of alternate rows in tables, and attach specific code examples.

Implementation method:

Using JQuery's selector and traversal method, you can easily achieve the effect of alternating background colors of alternate rows in the table. The specific steps are as follows:

First, make sure to introduce the JQuery library into the HTML file. You can introduce it through CDN or download it to a local file. After introducing the JQuery library, we can write JQuery code in the <script> tag. </script>
Add a specific class name or identifier to the rows in the table that need to achieve alternating background colors. For example, we can add a class of "even-row" to the even-numbered rows, and a class of "odd-" to the odd-numbered rows. row".
Use the JQuery selector to select the rows that need to be added with a background color, and then add corresponding background color styles to these rows through the methods provided by JQuery.

Specific code example:

The following is a simple example that demonstrates how to use JQuery to implement alternating background colors of alternate rows in a table:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>表格隔行交替背景色</title>
<script src="https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.min.js"></script>
<style>
    .even-row {
        background-color: #f2f2f2;
    }
</style>
</head>
<body>

<table id="myTable">
    <tr><td>行1</td></tr>
    <tr><td>行2</td></tr>
    <tr><td>行3</td></tr>
    <tr><td>行4</td></tr>
</table>

<script>
    $(document).ready(function() {
        $("#myTable tr:even").addClass("even-row");
    });
</script>

</body>
</html>

In the above code, we use JQuery's selector ":even" to select the even rows in the table, and add the "even-row" class to these rows, thereby achieving the effect of alternating background colors for alternate rows.

Through the above code examples, we can see that using JQuery to achieve alternating background colors of alternate rows in tables is a simple and effective method. This method is not only simple and efficient, but also adds a more beautiful and readable visual effect to the table. I hope this article can help readers in need and improve the display effect of web tables.
