Framework7延迟加载延迟加载|Framework7

当用于大型多媒体文件时, 延迟加载会花费一些时间来加载图片, 视频等。
例
让我们以一个示例来演示延迟加载的用法, 该延迟加载通过触发Framework7中的“ lazy”事件来加载图像：

< !DOCTYPE html> < html> < head> < meta name = "viewport" content = "width = device-width, initial-scale = 1, maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" /> < meta name = "apple-mobile-web-app-capable" content = "yes" /> < meta name = "apple-mobile-web-app-status-bar-style" content = "black" /> < title> Lazy Loading< /title> < link rel = "stylesheet" href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" /> < link rel = "stylesheet" href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.colors.min.css" /> < /head> < body> < div class = "views"> < div class = "view view-main"> < div class = "pages"> < div data-page = "home" class = "page navbar-fixed"> < div class = "navbar"> < div class = "navbar-inner"> < div class = "left"> < /div> < div class = "center"> Lazy Loading< /div> < div class = "right"> < /div> < /div> < /div> < div class = "page-content"> < div class = "swiper-container"> < div class = "swiper-wrapper"> < div class = "swiper-slide"> < img data-src = "http://lorempixel.com/1600/1200/nature/1" class = "swiper-lazy"> < div class = "preloader"> < /div> < /div> < div class = "swiper-slide"> < img data-src = "http://lorempixel.com/1600/1200/nature/2" class = "swiper-lazy"> < div class = "preloader"> < /div> < /div> < div class = "swiper-slide"> < img data-src = "http://lorempixel.com/1600/1200/nature/3" class = "swiper-lazy"> < div class = "preloader"> < /div> < /div> < div class = "swiper-slide"> < img data-src = "http://lorempixel.com/1600/1200/nature/4" class = "swiper-lazy"> < div class = "preloader"> < /div> < /div> < div class = "swiper-slide"> < img data-src = "http://lorempixel.com/1600/1200/nature/5" class = "swiper-lazy"> < div class = "preloader"> < /div> < /div> < /div> < div class = "swiper-pagination color-white"> < /div> < /div> < /div> < /div> < /div> < /div> < /div> < script type = "text/javascript" src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"> < /script> < style> .swiper-container {height:100%; }.swiper-slide {background:#000; position:relative; height:100%; }.swiper-slide img {position:absolute; left:50%; top:50%; max-width:100%; max-height:100%; width:auto; height:auto; -webkit-transform:translate(-50%, -50%); transform:translate(-50%, -50%); }< /style> < script> var myApp = new Framework7(); var mySwiper = new Swiper('.swiper-container', {preloadImages: false, lazyLoading: true, pagination: '.swiper-pagination'})< /script> < /body> < /html>
