今天，跟大家分享一些网页特效源码，希望对大家有帮助。

1、evanyou 效果-彩带的实现，效果如下

注：这个主要用的是 Canvas 画布实现的，点击背景绘制新的图形，代码如下：

<canvas id="evanyou" width="1920" height="934"></canvas> /*CSS代码:*/
<style type="text/css">
  #evanyou {
    position: fixed;
    width: 100%;
    height: 100%;
    left: 0;
    top: 0;
  }
</style>
<script>
  var c = document.getElementById('evanyou'),
    x = c.getContext('2d'),
    pr = window.devicePixelRatio || 1,
    w = window.innerWidth,
    h = window.innerHeight,
    f = 90,
    q, m = Math,
    r = 0,
    u = m.PI * 2,
    v = m.cos,
    z = m.random;
  c.width = w * pr;
  c.height = h * pr;
  x.scale(pr, pr);
  x.globalAlpha = 0.6;
  function evanyou() {
    x.clearRect(0, 0, w, h) q = [{
      x: 0,
      y: h * .7 + f
    }, {
      x: 0,
      y: h * .7 - f
    }]
    while(q[1].x <
      w + f) d(q[0], q[1])
  }
  function d(i, j) {
    x.beginPath() x.moveTo(i.x, i.y) x.lineTo(j.x, j.y) var k = j.x + (z() * 2 - 0.25) * f,
      n = y(j.y) x.lineTo(k, n) x.closePath() r -= u / -50 x.fillStyle = '#' + (v(r) * 127 + 128 << 16 | v(r + u / 3) * 127 + 128 << 8 | v(r + u / 3 * 2) * 127 + 128).toString(16) x.fill() q[0] = q[1] q[1] = {
        x: k,
        y: n
      }
  }
  function y(p) {
    var t = p + (z() * 2 - 1.1) * f
    return(t > h || t <
      0) ? y(p) : t
  }
  document.onclick = e vanyou document.ontouchstart = e vanyou evanyou();
</script>

2、返回顶部特效（滚动条上移或者点击会自动隐藏和显示），效果如下:

代码如下：

//Html代码: body>
<!--回到顶部-->
<div id="back-to-top" class="red" data-scroll="body" style="top:-46px;color:red;">回到顶部 </div>
<!--撑开网页代码-->
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<p>hello</p>
<!--以上是撑开网页代码-->//CSS样式 #back-to-top { position:fixed; right:50px; z-index:9; width:70px; height:900px; background:url('/Content/Images/scroll.png'); transition:0.5s; cursor:pointer; } //JS部分:
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script type="text/javascript">
  window.onload = function() {
    // 利用 data-scroll 属性，滚动到任意 dom 元素           
    $.scrollto = function(scrolldom, scrolltime) {
      $(scrolldom).click(function() {
        var scrolltodom = $(this).attr("data-scroll");
        $(this).addClass("active").siblings().removeClass("active");
        $('html, body').animate({
          scrollTop: $(scrolltodom).offset().top
        }, scrolltime);
        return false;
      });
    };
    //判断位置控制 返回顶部的显隐
    if($(window).width() > 800) {
      //如果窗体的宽度大于800
      var backTo = $("#back-to-top");
      //获取back-to-top对象
      var backHeight = $(window).height() - 980 + 'px';
      //让window高度减980
      $(window).scroll(function() {
        if($(window).scrollTop() > 700 && backTo.css('top') === '-900px') {
          backTo.css('top', backHeight);
        } else if($(window).scrollTop() <= 700 && backTo.css('top') !== '-900px') {
          backTo.css('top', '-900px');
        }
      });
    }
    //启用            
    $.scrollto("#back-to-top", 800);
  }
</script>

3、左下角探头效果

PS：这个图片在网页的左下角，鼠标移动上去探头效果，代码如下

<div class="xm"> <img src="/Content/Images/xiaomai.png" /> </div> //CSS代码
<style>
  .xm {
    position: fixed;
    bottom: 0;
    left: 0;
    z-index: 1;
    font-size: 0;
    transition: all .3s ease-in-out;
    transform: translateY(3px);
  }
  
  .xm:hover {
    -webkit-transform: translateY(0);
    -ms-transform: translateY(0);
  }
  
  .xm img {
    width: 50px;
  }
</style>

4、文字翻转效果（点击翻转，一开始加载页面也翻转）

代码如下：

<header class="header-description">
  <div id="site-header">
    <h1>                <a href="@Url.Action("JianJIe", "Home")" title="Anneke.cn">日月君地带</a>            </h1>
    <p class="typed">
      <a href="@Url.Action(" JianJIe ", "Home ")" title="Anneke.cn">日月君地带</a><span class="typed-cursor">|</span></p>
  </div>
</header> //CSS代码
<style type="text/css">
  #site-header {
    font-size: 40px !important;
    font-weight: 700;
    z-index: 1;
    text-align: center;
    position: relative;
    top: 180px;
    font-family: kilsonburg, "Avenir Next", Helvetica, Arial, "Lantinghei SC", "Microsoft YaHei", sans-serif;
    font-size: 34px;
    text-shadow: 0 1px 1px #47456d;
    margin-bottom: 130px;
    animation: show-site-title 1s ease-out;
    -o-animation: show-site-title 1s ease-out;
    -moz-animation: show-site-title 1s ease-out;
    -webkit-animation: show-site-title 1s ease-out;
  }
  
  #site-header h1 {
    display: none;
  }
  
  #site-header a {
    color: #fff;
    font-weight: 400;
  }
  
  body {
    background-color: #0094ff;
  }
</style>
<script>
  $(document).ready(function($) {
    $(".typed a").typed({
      strings: ["这里是地狱之门", "日月君地带"],
      typeSpeed: 30,
      backSpeed: 30,
      backDelay: 700
    });
  });
  //PS：需要引入两个文件：一个是jquery-1.8.2.min.js文件，一个是 typed.min.js文件（PS：自定义的，下面会贴出来）
</script>

typed.min.js 代码:

! function(t) {
  "use strict";
  var s = function(s, e) {
    this.el = t(s), this.options = t.extend({}, t.fn.typed.defaults, e), this.isInput = this.el.is("input"), this.attr = this.options.attr, this.showCursor = this.isInput ? !1 : this.options.showCursor, this.elContent = this.attr ? this.el.attr(this.attr) : this.el.text(), this.contentType = this.options.contentType, this.typeSpeed = this.options.typeSpeed, this.startDelay = this.options.startDelay, this.backSpeed = this.options.backSpeed, this.backDelay = this.options.backDelay, this.stringsElement = this.options.stringsElement, this.strings = this.options.strings, this.strPos = 0, this.arrayPos = 0, this.stopNum = 0, this.loop = this.options.loop, this.loopCount = this.options.loopCount, this.curLoop = 0, this.stop = !1, this.cursorChar = this.options.cursorChar, this.shuffle = this.options.shuffle, this.sequence = [], this.build()
  };
  s.prototype = {
    constructor: s,
    init: function() {
      var t = this;
      t.timeout = setTimeout(function() {
        for(var s = 0; s < t.strings.length; ++s) t.sequence[s] = s;
        t.shuffle && (t.sequence = t.shuffleArray(t.sequence)), t.typewrite(t.strings[t.sequence[t.arrayPos]], t.strPos)
      }, t.startDelay)
    },
    build: function() {
      var s = this;
      if(this.showCursor === !0 && (this.cursor = t('<span class="typed-cursor">' + this.cursorChar + "</span>"), this.el.after(this.cursor)), this.stringsElement) {
        s.strings = [], this.stringsElement.hide();
        var e = this.stringsElement.find("p");
        t.each(e, function(e, i) {
          s.strings.push(t(i).html())
        })
      }
      this.init()
    },
    typewrite: function(t, s) {
      if(this.stop !== !0) {
        var e = Math.round(70 * Math.random()) + this.typeSpeed,
          i = this;
        i.timeout = setTimeout(function() {
          var e = 0,
            r = t.substr(s);
          if("^" === r.charAt(0)) {
            var o = 1;
            /^\^\d+/.test(r) && (r = /\d+/.exec(r)[0], o += r.length, e = parseInt(r)), t = t.substring(0, s) + t.substring(s + o)
          }
          if("html" === i.contentType) {
            var n = t.substr(s).charAt(0);
            if("<" === n || "&" === n) {
              var a = "",
                h = "";
              for(h = "<" === n ? ">" : ";"; t.substr(s).charAt(0) !== h;) a += t.substr(s).charAt(0), s++;
              s++, a += h
            }
          }
          i.timeout = setTimeout(function() {
            if(s === t.length) {
              if(i.options.onStringTyped(i.arrayPos), i.arrayPos === i.strings.length - 1 && (i.options.callback(), i.curLoop++, i.loop === !1 || i.curLoop === i.loopCount)) return;
              i.timeout = setTimeout(function() {
                i.backspace(t, s)
              }, i.backDelay)
            } else {
              0 === s && i.options.preStringTyped(i.arrayPos);
              var e = t.substr(0, s + 1);
              i.attr ? i.el.attr(i.attr, e) : i.isInput ? i.el.val(e) : "html" === i.contentType ? i.el.html(e) : i.el.text(e), s++, i.typewrite(t, s)
            }
          }, e)
        }, e)
      }
    },
    backspace: function(t, s) {
      if(this.stop !== !0) {
        var e = Math.round(70 * Math.random()) + this.backSpeed,
          i = this;
        i.timeout = setTimeout(function() {
          if("html" === i.contentType && ">" === t.substr(s).charAt(0)) {
            for(var e = "";
              "<" !== t.substr(s).charAt(0);) e -= t.substr(s).charAt(0), s--;
            s--, e += "<"
          }
          var r = t.substr(0, s);
          i.attr ? i.el.attr(i.attr, r) : i.isInput ? i.el.val(r) : "html" === i.contentType ? i.el.html(r) : i.el.text(r), s > i.stopNum ? (s--, i.backspace(t, s)) : s <= i.stopNum && (i.arrayPos++, i.arrayPos === i.strings.length ? (i.arrayPos = 0, i.shuffle && (i.sequence = i.shuffleArray(i.sequence)), i.init()) : i.typewrite(i.strings[i.sequence[i.arrayPos]], s))
        }, e)
      }
    },
    shuffleArray: function(t) {
      var s, e, i = t.length;
      if(i)
        for(; --i;) e = Math.floor(Math.random() * (i + 1)), s = t[e], t[e] = t[i], t[i] = s;
      return t
    },
    reset: function() {
      var t = this;
      clearInterval(t.timeout);
      var s = this.el.attr("id");
      this.el.after('<span id="' + s + '"/>'), this.el.remove(), "undefined" != typeof this.cursor && this.cursor.remove(), t.options.resetCallback()
    }
  }, t.fn.typed = function(e) {
    return this.each(function() {
      var i = t(this),
        r = i.data("typed"),
        o = "object" == typeof e && e;
      r || i.data("typed", r = new s(this, o)), "string" == typeof e && r[e]()
    })
  }, t.fn.typed.defaults = {
    strings: ["These are the default values...", "You know what you should do?", "Use your own!", "Have a great day!"],
    stringsElement: null,
    typeSpeed: 0,
    startDelay: 0,
    backSpeed: 0,
    shuffle: !1,
    backDelay: 500,
    loop: !1,
    loopCount: !1,
    showCursor: !0,
    cursorChar: "|",
    attr: null,
    contentType: "html",
    callback: function() {},
    preStringTyped: function() {},
    onStringTyped: function() {},
    resetCallback: function() {}
  }
}(window.jQuery);

5、在离开网页时，触发事件（这里以改变标题为例）

注:这里鼠标移开时，同时改变网页 title 和 icon 图标，代码如下：

<head>
  <meta name="viewport" content="width=device-width" />
  <title>IT发烧友，一个真正的技术交流群</title>
  <link rel="shortcut icon" href="/Content/Images/icon.png"> </head> //JS部分
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script>
  window.onload = function() {
    var OriginTitile = document.title;
    var titleTime;
    document.addEventListener('visibilitychange', function() {
      if(document.hidden) {
        $('[rel="shortcut icon"]').attr('href', "/Content/Images/fail.ico");
        document.title = '(●—●)喔哟，崩溃啦！';
        clearTimeout(titleTime);
      } else {
        $('[rel="shortcut icon"]').attr('href', "/Content/Images/icon.png");
        document.title = '(/≧▽≦/)咦！又好了！' + OriginTitile;
        titleTime = setTimeout(function() {
          document.title = OriginTitile;
        }, 2000);
      }
    });
  }
</script>

6、移入网页时改变鼠标的样式

PS:这个只要在样式里面设置即可，也就是移入时显示一张图片，代码如下：

//css如下所示
<style>
  abbr,
  acronym,
  address,
  applet,
  article,
  aside,
  audio,
  b,
  big,
  blockquote,
  body,
  canvas,
  caption,
  center,
  cite,
  code,
  dd,
  del,
  details,
  dfn,
  dl,
  dt,
  em,
  embed,
  fieldset,
  figcaption,
  figure,
  footer,
  form,
  h1,
  h2,
  h3,
  h4,
  h5,
  h6,
  header,
  html,
  iframe,
  img,
  ins,
  kbd,
  label,
  legend,
  li,
  mark,
  menu,
  nav,
  object,
  ol,
  output,
  p,
  pre,
  q,
  ruby,
  s,
  samp,
  section,
  small,
  span,
  strike,
  strong,
  sub,
  summary,
  sup,
  table,
  tbody,
  td,
  tfoot,
  th,
  thead,
  time,
  tr,
  tt,
  u,
  ul,
  var,
  video {
    margin: 0;
    padding: 0;
    cursor: url('/Content/Image/cursor.ico'), auto;
  }
</style>

7、文字向上滚动效果（PS：鼠标悬停停止滚动）

代码如下:

<div align="center" id="demo">
  <div id="demo1"> 我是滚动内容<br/> 你来抓我啊<br/> 嗖嗖嗖<br/> 2333333333333333333333333 </div>
  <div id="demo2"></div>
</div>
<style>
  #demo {
    overflow: hidden;
    height: 200px;
    width: 250px;
    border: 1px solid #6699cc;
    font-size: 14px;
    color: #336699;
    line-height: 22px;
    text-align: left;
    padding: 10px;
  }
</style>
<script>
  //JS代码: 
  var demo = document.getElementById("demo");
  var demo1 = document.getElementById("demo1");
  var demo2 = document.getElementById("demo2");
  var speed = 30;
  //滚动速度值,值越大速度越慢
  var nnn = 200 / demo1.offsetHeight;
  for(i = 0; i < nnn; i++) {
    demo1.innerHTML += "<br />" + demo1.innerHTML
  }
  demo2.innerHTML = d emo1.innerHTML
  //克隆demo2为demo1 
  function Marquee() {
    if(demo2.offsetTop - demo.scrollTop <= 0)
      //当滚动至demo1与demo2交界时,demo跳到最顶端
      demo.scrollTop -= demo1.offsetHeight
    else {
      demo.scrollTop++ //如果是横向的 将 所有的 height top 改成 width left 
    }
  }
  var MyMar = s etInterval(Marquee, speed);
  //设置定时器,鼠标经过时清除定时器达到滚动停止的目的 
  demo.onmouseover = f unction() {
    clearInterval(MyMar)
  }
  //鼠标移开时重设定时器
  demo.onmouseout = f unction() {
    MyMar = s etInterval(Marquee, speed)
  }
</script>

8、 鼠标移入效果

鼠标移入，使区域旋转变色，代码如下：

//Style样式
<link href="~/Content/amazeui.min.css" rel="stylesheet" />
<style type="text/css">
  #XuanZhuan li {
    width: 200px;
    height: 50px;
    background-color: pink;
    margin-left: 15px;
    position: relative;
    float: left;
    list-style: none;
    margin-top: 15px;
  }
  
  div {
    width: 470px;
  }
  
  #XuanZhuan li:hover {
    cursor: pointer;
  }
</style> //Html标签
<div>
  <ul id="XuanZhuan">
    <li> 11111111111111111 </li>
    <li> 222222222222222 </li>
    <li> 333333333333333 </li>
    <li> 4444444444444444 </li>
  </ul>
</div> //Script
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script type="text/javascript">
  //在友情链接页面，鼠标放在li上,li旋转效果        
  $(function() {
    $("#XuanZhuan li").hover(function() {
      $(this).css("background-color", "yellow");
      $(this).attr("class", "am-animation-spin");
    }, function() {
      $(this).css("background-color", "pink");
      $(this).attr("class", "");
    });
  })
</script>

9、旋转星空，点击放烟花效果

实现代码:

<div> <canvas id="canvas"></canvas> <canvas id="snow"></canvas>
  <div class="am-g" style="position: fixed; bottom: 0px;">
    <div class="am-u-sm-12">
      <div style="z-index: 9999" id="player" class="aplayer"> </div>
    </div>
  </div>
</div> //CSS代码 canvas { position: fixed; width: 100%; height: 100%; z-index: -1; } //引入JS
<script src="~/Content/assets/js/jquery.min.js"></script>
<script src="~/Scripts/Blog/universe.js"></script>
<!--旋转背景-->
<script src="~/Scripts/Blog/Fireworks.js"></script>
<!--点击放烟花-->

universe.js

var canvas = document.getElementById('canvas'),
  ctx = canvas.getContext('2d'),
  w = canvas.width = window.innerWidth,
  h = canvas.height = window.innerHeight,
  hue = 217,
  stars = [],
  count = 0,
  maxStars = 1300; //星星数量 
var canvas2 = document.createElement('canvas'),
  ctx2 = canvas2.getContext('2d');
canvas2.width = 100;
canvas2.height = 100;
var half = canvas2.width / 2,
  gradient2 = ctx2.createRadialGradient(half, half, 0, half, half, half);
gradient2.addColorStop(0.025, '#CCC');
gradient2.addColorStop(0.1, 'hsl(' + hue + ', 61%, 33%)');
gradient2.addColorStop(0.25, 'hsl(' + hue + ', 64%, 6%)');
gradient2.addColorStop(1, 'transparent');
ctx2.fillStyle = gradient2;
ctx2.beginPath();
ctx2.arc(half, half, half, 0, Math.PI * 2);
ctx2.fill(); // End cache 
function random(min, max) {
  if(arguments.length < 2) {
    max = min;
    min = 0;
  }
  if(min > max) {
    var hold = max;
    max = min;
    min = hold;
  }
  return Math.floor(Math.random() * (max - min + 1)) + min;
}
 
function maxOrbit(x, y) {
  var max = Math.max(x, y),
    diameter = Math.round(Math.sqrt(max * max + max * max));
  return diameter / 2; //星星移动范围，值越大范围越小，

10、音乐播放组件

PS：此插件由迅雷提供，实现如下:

<div id="player1" class="aplayer">
  <pre class="aplayer-lrc-content">
[ti:断桥残雪]
[ar:Vae]
[al:断桥残雪（EP）]
[00:01.90]Vae - 断桥残雪
[00:05.16]词、曲 编曲：许嵩（Vae）
[00:08.16]
[00:24.99]寻不到花的折翼枯叶蝶
[00:30.09]永远也看不见凋谢
[00:36.90]江南夜色下的小桥屋檐
[00:42.04]读不懂塞北的荒野
[00:48.94]梅开时节因寂寞而缠绵
[00:54.07]春归后又很快湮灭
[01:01.21]独留我赏烟花飞满天
[01:06.03]摇曳后就随风飘远
[01:13.11]断桥是否下过雪
[01:15.83]我望着湖面
[01:18.77]水中寒月如雪
[01:21.78]指尖轻点融解
[01:24.81]断桥是否下过雪
[01:27.69]又想起你的脸
[01:30.66]若是无缘再见
[01:33.75]白堤柳帘垂泪好几遍
[02:03.83]寻不到花的折翼枯叶蝶
[02:09.12]永远也看不见凋谢
[02:15.84]江南夜色下的小桥屋檐
[02:21.17]读不懂塞北的荒野
[02:28.01]梅开时节因寂寞而缠绵
[02:33.09]春归后又很快湮灭
[02:39.79]独留我赏烟花飞满天
[02:45.19]摇曳后就随风飘远
[02:52.06]断桥是否下过雪
[02:54.83]我望着湖面
[02:57.80]水中寒月如雪
[03:00.82]指尖轻点融解
[03:03.85]断桥是否下过雪
[03:06.83]又想起你的脸
[03:09.90]若是无缘再见
[03:12.74]白堤柳帘垂泪好几遍
</pre>
</div>
//JS部分
<script type="text/javascript">
  //初始化APlayer音乐播放器插件。
  var ap = new APlayer({
    element: document.getElementById('player1'),
    narrow: false,
    autoplay: false, //是否自动播放
    showlrc: true, //是否显示歌词
    theme: '#66B7FF', //主题颜色
    music: {
      title: '断桥残雪',
      author: '许嵩大人',
      url: '/Content/Music/许嵩 - 断桥残雪.mp3',
      pic: '/Content/Music/dqcx.jpg',
    }
  });
  ap.init();
</script>
//引入JS部分
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<link href="//cdn.bootcss.com/aplayer/1.4.8/APlayer.min.css" rel="stylesheet">
<script src="//cdn.bootcss.com/aplayer/1.4.8/APlayer.min.js"></script>

11、点击弹出指定的内容

PS:点击弹出显示内容，过一会自动消失, 说白了也就是一个弹出内容插件，比 alert 好看些，代码如下：

<input type="button" value="显示获取到的内容" id="btn1" /> //JS代码
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/layer/layer.js"></script>
<script type="text/javascript">
  $(function() {
    $("#btn1").click(function() {
      layer.msg("我是弹出的内容");
    });
  })
</script>

利用上面的插件还可以实现 confirm 选择效果

实现代码：

layer.confirm('确定要删除?', {
  icon: 3,
  title: '提示'
}, function() {
  alert("当然确定了~");
});
