前言:这些小项目全都是自创的。 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:

<div id="container">   
        <div data-key="81" class="key">
            <kbd>Q</kbd>

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

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>

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(){
