Realization of Carousel Graph by Js

Realization idea

This may be one of the simplest implementations of a broadcast picture. To achieve this effect by changing the src of the picture, we first need to unify the naming format of the picture, such as pic01.jpg,pic02.jpg. And then use the timer to change the name of the src image link in the img tag through js to achieve the switching effect. The code is as follows:

Realize the effect

Width: 900px; height: 400px; margin:100px auto;} .lunbo img {width: 100%; height:100%;}

Var index = 1; function lunbo () {index+ +; / / determine whether index is greater than 3 if (index > 3) {index = 1;} / / get img object var img = document.getElementById ("lunbo_img"); img.src = ". / pic/img" + index+ ".jpeg" } / / 2. Define the timer setInterval (lunbo,2000); / * remember that calling the lunbo method in the timer cannot add (), setInterval (lunbo,2000); if you add (), the lunbo () method will be executed, causing the timer to be useless.
