1. 当弹出键盘时，会改变页面高度，影响页面样式
通过window.onsize事件可以控制键盘弹出或消失的时候的样式
var h = document.body.scrollHeight // 用onresize事件监控窗口或框架被调整大小，先把一开始的高度记录下来 window.onresize = function () { // 如果当前窗口小于一开始记录的窗口高度，那就让当前窗口等于一开始窗口的高度 // alert("h:" + h + "; <br> height:" + document.body.scrollHeight) if (document.body.scrollHeight < h) { document.body.style.height = h + "px" } }
2. H5无法控制手机横屏的操作（安卓和ios可以），为了避免某些情况下横屏，解决方案如下
