Jquery Tips: How to achieve alternating background colors of alternate rows in tables

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.

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
