Web design tips: Jquery achieves interlaced color changing effect

In web design, the interlaced color change effect is a common method to beautify the page, which can make the page look clearer and more beautiful. By using JQuery, we can easily achieve this effect. The following will introduce how to use JQuery to achieve the interlaced color changing effect, and attach specific code examples.

First, we need to introduce the JQuery library, and you can add the following code to the head of the page:

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

Next, we need to write some CSS styles to define the background color of odd and even rows. For example, we can use the following style:

.even {
    background-color: #f2f2f2;
}

.odd {
    background-color: #e9e9e9;
}

Then, we can use JQuery to achieve the interlaced color change effect. The specific code is as follows:

$(document).ready(function() {
    $('tr:even').addClass('even');
    $('tr:odd').addClass('odd');
});

In the above code, we first use the $(document).ready() method to ensure that the DOM structure of the page has been loaded. We then select all even rows (using the :even selector) and odd rows (using the :odd selector) and add even and odd classes respectively to apply the previously defined styles.

Finally, in the table in HTML, we can use this code like this:

<table>
    <tr>
        <td>第一行</td>
        <td>内容</td>
    </tr>
    <tr>
        <td>第二行</td>
        <td>内容</td>
    </tr>
    <tr>
        <td>第三行</td>
        <td>内容</td>
    </tr>
</table>

Through the above steps, we have successfully used JQuery to achieve the interlaced color changing effect. Doing so will not only make the page more organized and beautiful, but also improve the user experience. Hope the above code examples are helpful to you!
