现在的网站有的时候为了简洁就是很多的单页滑屏滚动介绍,主要呈现方式有两种,一种是整体的元素一直排列下去,假设有五个需要展示的全屏页面,那么高度是500%,只是展示100%,剩下的可以通过transform进行Y轴定位,也可以通过margin-top实现,第二种就是所有的子元素和页面一样,都显示在当前页面,简单的实现第一种页面。
Html代码:
<div class="container"> <div class="wrapper"> <div class="page page0 active" data-page="0"> 第一页 博客园-FlyElephant </div> <div class="page page1" data-page="1"> 第二页 </div> <div class="page page2" data-page="2"> 第三页 </div> <div class="page page3" data-page="3"> 第四页 </div> </div> </div>
页面样式:
html, body { height: 100%; padding: 0px; margin: 0px; } .container { height: 100%; overflow: hidden; } .wrapper { height: 100%; touch-action: none; transition: all 1000ms ease; } .page { height: 100%; width: 100%; } .page0 { background: #551A8B; } .page1 { background: #FF8247; } .page2 { background: #CD919E; } .page3 { background: #98FB98; }
鼠标滑动控制代码,如果需要获取鼠标的滚轮事件可以直接通过JavaScript,也可以通过query.mousewheel.min.js插件来写,原生态的JS:
/** This is high-level function. * It must react to delta being more/less than zero. */function handle(delta) { if (delta < 0) …; else …;}/** Event handler for mouse wheel event. */function wheel(event){ var delta = 0; if (!event) /* For IE. */ event = window.event; if (event.wheelDelta) { /* IE/Opera. */ delta = event.wheelDelta/120; } else if (event.detail) { /** Mozilla case. */ /** In Mozilla, sign of delta is different than in IE. * Also, delta is multiple of 3. */ delta = -event.detail/3; } /** If delta is nonzero, handle it. * Basically, delta is now positive if wheel was scrolled up, * and negative, if wheel was scrolled down. */ if (delta) handle(delta); /** Prevent default actions caused by mouse wheel. * That might be ugly, but we handle scrolls somehow * anyway, so don't bother here.. */ if (event.preventDefault) event.preventDefault(); event.returnValue = false;}/** Initialization code. * If you use your own event management code, change it as required. */if (window.addEventListener) /** DOMMouseScroll is for mozilla. */ window.addEventListener('DOMMouseScroll', wheel, false);/** IE/Opera. */window.onmousewheel = document.onmousewheel = wheel;
通过JavaScript插件控制控制滚动的代码:
<script type="text/javascript"> $(function() { $('.container').on('mousewheel', function(event) { //mac自然状态向上是-1 //window向上滑动时候是1 向下-1 console.log(event.deltaX, event.deltaY, event.deltaFactor); var currentPage = parseInt($('.active').attr('data-page')); if (event.deltaY > 0) { var prevpage = currentPage - 1; if (prevpage >=0) { $('.page' + prevpage).addClass('active'); $('.page' + currentPage).removeClass('active'); $('.wrapper').css({ 'transform': 'translate(0,' + (prevpage * -100) + '%)' }); } } else { var nextpage = currentPage + 1; if (nextpage < 4) { $('.page' + nextpage).addClass('active'); $('.page' + currentPage).removeClass('active'); $('.wrapper').css({ 'transform': 'translate(0,' + (nextpage * -100) + '%)' }); } } }); }); </script>
关于滚轮的时间的控制,以及不确定页面元素时候的代码没有给出判断,大体思路不变,其他的仅供参考~
