Detailed explanation of using jquery to create carousel images on PC
This time I will bring you a detailed explanation of how to use jquery to make a PC-side carousel chart. What are the precautions for using jquery to make a PC-side carousel chart. The following is a practical case. Get up and take a look.
I haven’t been very busy with other projects recently. I was assigned to make a new page for the company’s official website project (I have never been exposed to the company’s official website project before). There is a place where carousel images are used. At first, I wanted to use it directly. It would be nice to implement the swiper.js plug-in, but I found that swiper.js had not been introduced in the official website project before. After thinking about it, I decided not to introduce it to avoid having to add another network request. Since jQuery has been used in the project , then simply use jQuery to write a carousel image.
Now take out the code for the carousel picture you wrote separately, make a small demo and write it here to record it (the picture of the carousel picture in the demo was randomly found online)
Achieved effects:
1. Automatic carousel (carousel time interval is customized in js code)
2. Click the left and right buttons to achieve manual switching
3. The small dot at the bottom displays the active state according to the position of the switched image.
4. The mouse passes through the carousel area, stops the carousel, and leaves the carousel area to start the carousel.
The code directory results are as follows:
##1. index.html
Note: Here are 5 pictures as an example. The actual carousel on the page shows users 5 different pictures. However, for the sake of the continuity of the carousel effect, a fifth picture is added in front of the first picture and after the fifth picture. The first picture, so there are 7 pictures in the demo structure, and the size of each picture must be the same (the width and height here are 720*350px).<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>PC-jquery版轮播图</title> <link rel="stylesheet" href="css/style.css" rel="external nofollow" > </head> <body> <p class="layout"> <h2 style="text-align: center;">PC-jquery版轮播图</h2> <p class="slide" id="slide"> <p id="outer" class="outer"> <ul id="inner" class="inner"> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-5</p><img src="images/slide-5.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-1</p><img src="images/slide-1.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-2</p><img src="images/slide-2.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-3</p><img src="images/slide-3.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-4</p><img src="images/slide-4.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-5</p><img src="images/slide-5.jpg"></a></li> <li><a href="http://www.baidu.com" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><p>图片-1</p><img src="images/slide-1.jpg"></a></li> </ul> <!--底部小圆点--> <ol class="dot" id="dot"> <li class="active"></li> <li></li> <li></li> <li></li> <li></li> </ol> </p> <!--左右两侧的点击切换按钮--> <p class="arrow-box"> <p class="arrow arrow-l" id="arrow_l">‹</p> <p class="arrow arrow-r" id="arrow_r">›</p> </p> </p> </p> <script src="js/jquery.min.js"></script> <script src="js/index.js"></script> </body> </html>
