移动端页面适配问题

# 移动开发 2024-05-05 14:16 0 35 来源：云博客

移动端页面满屏自适应方案（采用rem作为单位，设计稿为750 * 1334）

修改自阿里的lib-flexible，与lib-flexible相比，删除了dpr，保留rem
满屏自适应，要求设计稿为750 * 1334
单位换算为1rem = 50px

代码引入：

<head> <script>function refreshRem(){var e=docEl.getBoundingClientRect().width,t=docEl.getBoundingClientRect().height;if(e/t>750/1334)var i=t/26.68;else var i=e/15;docEl.style.fontSize=i+"px"}var win=window,doc=win.document,docEl=doc.documentElement,tid;win.addEventListener("resize",function(){clearTimeout(tid),tid=setTimeout(refreshRem,300)},!1),win.addEventListener("pageshow",function(e){e.persisted&&(clearTimeout(tid),tid=setTimeout(refreshRem,300))},!1),refreshRem();</script></head>

源码

var win = window;var doc = win.document;var docEl = doc.documentElement;var tid;function refreshRem(){ var width = docEl.getBoundingClientRect().width; var height = docEl.getBoundingClientRect().height; if ((width / height) > (750 / 1334)) { var rem = height / (1334 / 50); } else { var rem = width / (750 / 50); } docEl.style.fontSize = rem + ‘px‘;}win.addEventListener(‘resize‘, function() { clearTimeout(tid); tid = setTimeout(refreshRem, 300);}, false);win.addEventListener(‘pageshow‘, function(e) { if (e.persisted) { clearTimeout(tid); tid = setTimeout(refreshRem, 300); }}, false);refreshRem();
