// 横竖屏幕提醒
(function transverse() {
if (window.orientation == 90 || window.orientation == -90) {
var t=$(window).scrollTop()
$('#hengping').hide();
// setTimeout(function(){
$(window).scrollTop(t+1);
// 横屏
$('#hengping').show(); } else if (window.orientation == 180 || window.orientation === 0) {
//竖屏
var t=$(window).scrollTop()
$('#hengping').hide();
// setTimeout(function(){
$(window).scrollTop(t+1); // },2000)
}
window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", transverse, false);
})();
</script> <!-- ios 微信端出现这样问题 安卓微信测试了几台没有这个问题--> </html>
此方法灵感来自京东移动端页面，有兴趣的朋友可以看看京东手机端的效果
注：在手机ios升级到了11版本，这个问题就没有了，不知道11以下会不会还有
