Question

我正在寻找一个剧本！我想做的就像这个网站的页脚（背景图像之间的动画，它写的＆＃39;＆＃39;不要错过任何更新＆＃39;＆＃39;）：{ {3}}

有没有人知道类似的脚本或能够从这个网站获取它？

感谢您的回答！

Answer 1

这就是我用几条jQ线来做的事情：

＆＃13;

var $bg = $('#bg'),
    $bgDIV = $('div', $bg), // Cache  your elements
    n = $bgDIV.length,      // count them (used to loop with % reminder)
    c = 0;                  //  counter

(function loopBG(){ 
  $bgDIV.eq(++c%n).hide().appendTo($bg).fadeTo(3000,1, loopBG);
}());   // start fade animation

＆＃13;

*{margin:0; padding:0;}

body{
  width:100%;
  height:100%;
}

#bg{
  position:absolute;
  top:0;
  width:100%;
  height:100%;
}
#bg:after{
  content:"";
  position:absolute;
  top:0; left:0;
  z-index:1;
  width:100%;
  height:100%;
  background:url(//i.stack.imgur.com/D0AZ1.png);
}
#bg > div{
  position:absolute;
  top:0;
  width:100%;
  height:100%;
  background: none 50%;
  background-size: cover;
}
#bg > #one{   background-image: url('//i.stack.imgur.com/T3U9b.png'); }
#bg > #two{   background-image: url('//i.stack.imgur.com/UKeA2.png'); }
#bg > #three{ background-image: url('//i.stack.imgur.com/hrArW.png'); }

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="bg">
    <div id="one"></div>
    <div id="two"></div>
    <div id="three"></div>
  </div>

＆＃13;

如果您对其来源进行分析，则处理此动画的代码位于以下文件中：

https://getgoldee.com/js/main.js

代码非常简单：

var footerBgContainer = $('.footer-bgs');

function setFooterBackground(bgNumber) {
    var prev = footerBgContainer.find('.bg');

    setTimeout(function () {
        prev.remove();
    }, 4100);

    var el = document.createElement('div');
    el.className += 'bg bg' + bgNumber;

    footerBgContainer.append(el);

    setTimeout(function () {
        el.className += ' show';
    }, 20);
}

function footerBgRotating(interval) {
    var current = 1;

    setInterval(function () {
        setFooterBackground((current % 3) + 1);
        current++;
    }, interval);
}

footerBgRotating(4000);

如您所见，它使用超时功能更改CSS类。

样式是:(动画在CSS中）

footer .bg {
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    z-index: -1;
    opacity: 0;
    -webkit-transition: opacity 4s linear;
    -moz-transition: opacity 4s linear;
    -o-transition: opacity 4s linear;
    transition: opacity 4s linear
}

footer .bg.show {
    opacity: 1;
    -webkit-transition: opacity 4s linear;
    -moz-transition: opacity 4s linear;
    -o-transition: opacity 4s linear;
    transition: opacity 4s linear
}

footer .bg.bg1 {
    background: url("../img/footer-bg1.png") no-repeat;
    background-size: cover
}

footer .bg.bg2 {
    background: url("../img/footer-bg2.png") no-repeat;
    background-size: cover
}

footer .bg.bg3 {
    background: url("../img/footer-bg3.png") no-repeat;
    background-size: cover
}
