How to use highlight effect in jQuery?

In web development, the highlighting effect is a common interactive design that can highlight specific elements and attract the user's attention. In jQuery, the highlighting effect can be achieved through simple code, adding some dynamic and visual effects to the web page. This article will introduce how to implement highlighting effects in jQuery and provide specific code examples.

First, make sure the jQuery library is introduced in your web page. You can add the following code in the

tag:

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

Then, we can use the jQuery method to achieve the highlighting effect. The following is a simple example of adding a highlight effect to an element when the mouse is hovering over it:

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>



    
鼠标悬停在我上面

    <script>
        $(document).ready(function() {
            $("#element").hover(function() {
                $(this).addClass("highlight");
            }, function() {
                $(this).removeClass("highlight");
            });
        });
    </script>

In this example, we first define a style class .highlight, which sets the background color to yellow. Then use jQuery's hover() method. When the mouse hovers over the element with the ID element, the .highlight style class will be added to achieve high Bright effect. When the mouse moves out, the .highlight style class will be removed and restored to its original state.

In addition to using the hover() method, you can also trigger the highlight effect by clicking a button or other events. The following is an example that adds a highlight effect to the specified element when the button is clicked:

<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>



    
我是要被高亮的元素
    高亮

    <script>
        $(document).ready(function() {
            $("#highlightBtn").click(function() {
                $("#element").addClass("highlight");
            });
        });
    </script>

In this example, when the button is clicked, the element with the id element will be added .highlight Style class, which implements the highlighting effect.

Through the above two examples, you can see that it is very simple to achieve the highlighting effect in jQuery. With the powerful functions of jQuery, we can easily achieve various interactive effects and add more interactivity and attraction to web pages.
