网页上我们经常用一些轮番图片来导航,非常方便,下面直接上代码!
HTML部分
<div class="slideshow-container">
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<img src="img1.jpg" style="width:100%">
<div class="text">文本 1</div>
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 3</div>
<img src="img2.jpg" style="width:100%">
<div class="text">文本 2</div> </div>
<div class="mySlides fade">
<div class="numbertext">3 / 3</div>
<img src="img3.jpg" style="width:100%">
<div class="text">文本 3</div>
</div>
<a class="prev" onclick="plusSlides(-1)">❮</a> <a class="next" onclick="plusSlides(1)">❯</a></div><br>
<div style="text-align:center">
<span class="dot" onclick="currentSlide(1)"></span>
<span class="dot" onclick="currentSlide(2)"></span>
<span class="dot" onclick="currentSlide(3)"></span>
</div>
css部分
* {box-sizing:border-box}
body {font-family: Verdana,sans-serif;}
.mySlides {display:none} /* 幻灯片容器 */
.slideshow-container {
max-width: 1000px; position: relative; margin: auto;
} /* 下一张 & 上一张 按钮 */
.prev, .next {
cursor: pointer; position: absolute; top: 50%; width: auto; margin-top: -22px; padding: 16px; color: white; font-weight: bold; font-size: 18px; transition: 0.6s ease; border-radius: 0 3px 3px 0;
} /* 定位 "下一张" 按钮靠右 */
.next {
right: 0; border-radius: 3px 0 0 3px;
} /* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
background-color: rgba(0,0,0,0.8);
} /* 标题文本 */
.text {
color: #f2f2f2; font-size: 15px; padding: 8px 12px; position: absolute; bottom: 8px; width: 100%; text-align: center;
} /* 数字文本 (1/3 等) */
.numbertext {
color: #f2f2f2; font-size: 12px; padding: 8px 12px; position: absolute; top: 0;
} /* 标记符号 */
.dot {
cursor:pointer; height: 13px; width: 13px; margin: 0 2px; background-color: #bbb; border-radius: 50%; display: inline-block; transition: background-color 0.6s ease;
}
.active, .dot:hover {
background-color: #717171;
} /* 淡出动画 */
.fade {
-webkit-animation-name: fade; -webkit-animation-duration: 1.5s; animation-name: fade; animation-duration: 1.5s;
}
@-webkit-keyframes fade {
from {opacity: .4} to {opacity: 1}
}
@keyframes fade {
from {opacity: .4} to {opacity: 1}
}
JavaScript部分
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block"; dots[slideIndex-1].className += " active";
}
最后一步就是给图片加超链接,这样用户点击图片就跳转了
是这怎么个情况,多多包涵,写的不好,排版有点难看,(毕竟是新人,就将就一点)
