前端的页面代码

news 来源：原创 2024/9/21 12:38:47

根据老师教的前端页面的知识，加上我也是借鉴了老师上课所说的代码，马马虎虎的写出了页面。如下代码：

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><link rel="stylesheet" href="./css/reset_css.css"><link rel="stylesheet" href="./css/data_css.css">
</head>
<body>
<div class="box"><div class="img1"><ul><li><img style="z-index: 1" src="./images/大图1.webp" alt=""></li><li><img src="./images/大图2.webp" alt=""></li><li><img src="./images/大图3.webp" alt=""></li><li><img src="./images/大图4.webp" alt=""></li></ul></div><div class="img2"><ul><li><img style="z-index: 11" src="./images/小图1.webp" alt=""></li><li><img src="./images/小图2.webp" alt=""></li><li><img src="./images/小图3.webp" alt=""></li><li><img src="./images/小图4.webp" alt=""></li></ul></div><div class="btn"><ul id="l1"><li><img style="z-index: 11" class="img1" src="./images/按钮左1.webp" alt=""></li><li><img class="img1" src="./images/按钮左2.webp" alt=""></li><li><img class="img1" src="./images/按钮左3.webp" alt=""></li><li><img class="img1" src="./images/按钮左4.webp" alt=""></li></ul><ul id="l2"><li><img style="z-index: 11" class="img2" src="./images/按钮右1.webp" alt=""></li><li><img class="img2" src="./images/按钮右2.webp" alt=""></li><li><img class="img2" src="./images/按钮右3.webp" alt=""></li><li><img class="img2" src="./images/按钮右4.webp" alt=""></li></ul></div><div class="cir"><ul><li></li><li></li><li></li><li></li></ul></div></div>
<script src="./js/date.js"></script>
</body>
</html>

运行此代码时，还需要联合css和js代码。

js代码如下：

var img=document.querySelectorAll(".box .img1 li img")
var img1=document.querySelectorAll(".box .img2 li img")
var cir=document.querySelectorAll(".box .cir li")
var btn=document.querySelectorAll(".box .btn .img1")
var btn1=document.querySelectorAll(".box .btn .img2")function f1(i) {for (let j=0;j<cir.length;j++){img[j].setAttribute("style", "z-index:0")img1[j].setAttribute("style", "z-index:0")btn[j].setAttribute("style", "z-index:0")btn1[j].setAttribute("style", "z-index:0")}img[i].setAttribute("style", "z-index:"+(i+1))img1[i].setAttribute("style", "z-index:"+(i+11))btn[i].setAttribute("style", "z-index:"+(i+11))btn1[i].setAttribute("style", "z-index:"+(i+11))
}for (let i=0;i<cir.length;i++){cir[i].onclick=function () {f1(i)index=i}
}var l1=document.getElementById("l1")
var l2=document.getElementById("l2")
var index=0
l2.onclick=function () {if (index == img.length-1){index=0}else{index++}f1(index)
}l1.onclick=function () {if (index == 0){index=img.length-1}else{index--}f1(index)
}

css代码如下：

1)data文件代码

.box{width: 1800px;height: 800px;margin: 20px auto;position: relative;left: 0;top: 0;
}
.box .img1 img{width: 1800px;height: 800px;position: absolute;top: 0;left: 0;
}
.box .img2 img{width: 700px;height: 350px;position: absolute;top: 30%;left: 30%;margin-top: -50px;margin-left: 15px;
}
.box .btn .img1{width: 75px;height: 75px;position: absolute;top: 50%;left: 20%;margin-left: 80px;margin-top: -75px;
}
.box .btn .img2{width: 75px;height: 75px;position: absolute;top: 50%;right: 20%;margin-right: 80px;margin-top: -75px;
}
.box .cir ul{position: absolute;left: 50%;bottom: 25%;transform: translateX(-50px);margin-left: -10px;z-index: 50;
}
.box .cir li{width: 10px;height: 10px;background-color: forestgreen;border-radius: 50%;float: left;margin-right: 5px;border: forestgreen solid 5px;
}
.box .cir li:hover{background-color: dimgray;
}
.box .btf #img3{position: absolute;bottom: 5%;left: 30%;margin-left: 40px;margin-bottom: 5px;z-index: 50;
}
.box .btf #img4{position: absolute;bottom: 5%;left: 40%;margin-left: 20px;margin-bottom: 5px;z-index: 50;
}
.box .btf #img5{position: absolute;bottom: 5%;left: 50%;margin-left: 35px;margin-bottom: 5px;z-index: 50;
}
.box .btf #img6{position: absolute;bottom: 5%;right: 30%;margin-right: 40px;margin-bottom: 5px;z-index: 50;
}

2）reset文件代码

/* http://meyerweb.com/eric/tools/css/reset/v2.0 | 20110126License: none (public domain)
*/html, body, div, span, applet, object, iframe,
h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed,
figure, figcaption, footer, header, hgroup,
menu, nav, output, ruby, section, summary,
time, mark, audio, video {margin: 0;padding: 0;border: 0;font-size: 100%;font: inherit;vertical-align: baseline;
}
/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure,
footer, header, hgroup, menu, nav, section {display: block;
}
body {line-height: 1;
}
ol, ul {list-style: none;
}
blockquote, q {quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {content: '';content: none;
}
table {border-collapse: collapse;border-spacing: 0;
}

结合上述前端代码，运行如下：
