618快到了送上自制前端小项目（html css js）

前言：这些小项目全都是自创的。

如果需要应用，或则转发的话请与

博主联系，感谢你们的理解，

1.自定义播放器

在页面中放置26个div，每个div中写一个字

母。html结构中引入8个音频结构。给每个

div绑定点击键盘事件。根据键盘的每个

keyCode的不同来动态绑定对应的音频文件。

当按下对应的键盘字母，增添css样式，

音频播放。放开时，存储点击的事件，

将对应的音频存储在一个数组中。

点击按钮，循环播放存储的音频数组

html:

function bind(){

2.图片自动消失

一张图片，在其右上角放置一个div

，分别得到那个元素，在div中插入数字

开启一个定时器，每隔一段时间减一。

直到为0.图片消失

<style>
.ad{
    width:400px;
    height:400px;
    background-image: url(img/1.jpg);
    position:relative;
    margin:200px auto;
}
#sj{
    display:block;
    width:40px;
    height:40px;
    line-height:30px;
    border-radius:50%;
    border:1px solid red;
    position:absolute;
    top:20px;
    right:20px;
    text-decoration: none;
    text-align: center;
    line-height: 40px;
    font-size: 20px;
}
</style>
</head>
<body>
    <div id="gg" class="ad">
        <a href="" > <span id="sj">5</span></a>
    </div>
<script>
var gg=document.getElementById("gg");
var sj=document.getElementById("sj")
var time=setInterval(function(){
    sj.innerHTML-=1;
    if(sj.innerHTML==0){
        gg.style.display="none";
        clearInterval(time);
    }
},1000);
</script>
</body>

yy3.小轮播图

放置三张图片，移动到那个图片，

改变他的偏移量。

*{
    padding:0;
    margin:0;
    }
body,html{
    width:100%;
     overflow:hidden;
    }
#wrap1{
    width:100%;
    position:absolute;
    bottom:0;
    left:0;
    text-align: center;
    }
#wrap1>img{
    width:64px;
    }
</style>
</head>
<body>
    <div id="wrap1">
        <img src="img/1.png" />
        <img src="img/2.png" />
        <img src="img/3.png" />
        <img src="img/4.png" />
        <img src="img/5.png" />
    </div>
<script type="text/javascript">
    window.onload=function(){
        var r=320
        var imgNodes=document.querySelectorAll("#wrap1>img")
        document.onmousemove=function(ev){
        ev=ev||event
        for(var i=0;i<imgNodes.length;i++){
var a= imgNodes[i].getBoundingClientRect().top+imgNodes[i].offsetHeight/2-ev.clientY
var b= imgNodes[i].getBoundingClientRect().right+ imgNodes[i].offsetWidth/2-ev.clientX
    var c=Math.sqrt(a*a+b*b)
            if(c>=r){
                    c=r
                    }
                 imgNodes[i].style.width=128-c*0.2+'px'
                    }
                }
            }
</script>

4.旋转音乐盒

旋转音乐盒

放置六张图片，将他们绝对定位。

根据所学css来对每一张图片进行定位

然后就是当点击哪一个图片时，播放

对应的音频音乐。

css：

*{
    padding:0;
    margin:0;
}
.cube{
    width:200px;
    height:200px;
    position: relative;    
    margin:200px auto;
   //使效果呈现3d效果        
    transform-style: preserve-3d;
    animation: rotate 30s infinite linear;
    }
@keyframes rotate{
    from{
       transform:rotateX(0deg) rotateY(0deg);
        }
    to{
       transform: rotateX(360deg) rotateY(360deg);
        }
}
html{
   //屏幕与我们的视距
    perspective: 10000px;
    }
.cube>div{
    width:200px;
    height:200px;
    position:absolute;
    opacity: 0.7;
    }
img{
    width:200px;
    height:200px;
    }
.box1{
    transform: rotateX(90deg) translateZ(100px);
    }
.box2{
    transform: rotateX(-90deg) translateZ(100px);
    }
.box3{
    transform:  rotateY(0deg) translateZ(100px);
    }
.box4{
    transform:  rotateY(180deg) translateZ(100px);
    }
.box5 {
    transform: rotateY(90deg) translateZ(100px);
    }
.box6  {
    transform: rotateY(-90deg) translateZ(100px);
    }
.change{
    transform:  translateZ(50px);
}
</style>

html：

<div class="cube">
    <div class="box1" data-key="1"><img src="./img/imgs/1.jpg"></div>
    <div class="box2" data-key="2"><img src="./img/imgs/2.jpg"></div>
    <div class="box3" data-key="3"><img src="./img/imgs/3.jpg"></div>
    <div class="box4" data-key="4"><img src="./img/imgs/4.jpg"></div>
    <div class="box5" data-key="5"><img src="./img/imgs/5.jpg"></div>
    <div class="box6" data-key="6"><img src="./img/imgs/6.jpg"></div>
</div>
<audio src="./img/audio/1.mp3" data-key="1"></audio>
<audio src="./img/audio/2.mp3" data-key="2"></audio>
<audio src="./img/audio/3.mp3" data-key="3"></audio>
<audio src="./img/audio/4.mp3" data-key="4"></audio>
<audio src="./img/audio/5.mp3" data-key="5"></audio>

js：

let divs=document.querySelectorAll('.cube>div')
let audios=document.querySelectorAll('audio')
    for(let i=0;i<divs.length;i++){
        for(let j=0;j<audios.length;j++){
            if(divs[i].dataset.key===audios[j].dataset.key){
                divs[i].onclick=function(){
                    audios[j].play()
                }
            }
        }
    }
