jquery implements mouse pointer color change

With the continuous development of Internet technology, people have higher and higher requirements for web pages. In the process of web design, changing color when the mouse is pointed is a common effect, which can add some interactivity to the page and make the user experience richer.

jQuery is a popular JavaScript library that is easy to use and has good cross-browser compatibility. Through the jQuery library, we can easily achieve the discoloration effect of mouse pointing, thereby improving the beauty and interactivity of web pages.

Below, I will introduce in detail how to use jQuery to achieve the discoloration effect of mouse pointing:

Step 1: Introduce the jQuery library

Before realizing the discoloration effect of mouse pointing, we need First introduce the jQuery library. The jQuery library can be introduced in the page with the following code:

<script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>

Here, we are using jQuery version 3.4.1 which is used by many large websites. By introducing the jQuery library, we can use many convenient and practical methods provided by it.

Step 2: Write CSS styles

Before using jQuery to achieve the color changing effect of mouse pointing, we need to first write the CSS style that needs to change when the mouse points. The color change when the mouse is pointed can be defined through the following code:

.hover-color {
  color: #ff0000;
}

Here, we use the CSS property color to specify the color of the text, setting it to red. We give it a class name .hover-color so that it can be applied to the corresponding element when the mouse is pointed at it.

Step 3: Use jQuery to achieve the mouse-pointing discoloration effect

The core step to achieve the mouse-pointing discoloration effect is to use jQuery's mouse events to add and delete accordingly when the mouse moves in and out. CSS class name.hover-color. The following is the implementation code:

$(document).ready(function() {
  $("p").mouseenter(function() {
    $(this).addClass("hover-color");
  });
  $("p").mouseleave(function() {
    $(this).removeClass("hover-color");
  });
});

Here, we use jQuery's document readiness event $(document).ready() to ensure that the corresponding code is executed after the page is loaded.

Next, we used jQuery’s mouse events mouseenter and mouseleave to correspond to the operations when the mouse moves in and out respectively. When the mouse moves in, we use the $(this) keyword to represent the currently pointed element, and use the .addClass() method to add the CSS class name .hover-color to it, making it appear red. When the mouse moves out, we use the .removeClass() method to remove the class name from the currently pointed element to restore its original color.

At this point, we have successfully used jQuery to achieve the discoloration effect of mouse pointing. It can be applied to the desired tag by replacing the p element with other elements. This method is simple and practical, and can help us quickly increase the interactivity and visual effects of web pages.

Summary:

This article introduces the steps to use jQuery to achieve the discoloration effect of mouse pointing. Using jQuery can achieve this effect more conveniently and quickly, enhancing the beauty and interactivity of web pages. I believe that through the explanation in this article, readers have a certain understanding and mastery of this technology and can flexibly apply it in actual development.
