话不多说，请看代码：
<script>
(function() {
var changeRem = function() {
document.getElementsByTagName('html')[0].style.fontSize = document.documentElement.clientWidth / 20 + 'px';
};
changeRem();
var t;
window.addEventListener('resize', function() {
clearTimeout(t);
t = setTimeout(changeRem, 300);
}, false);
window.addEventListener('pageshow', function(e) {
if (e.persisted) {
clearTimeout(t);
t = setTimeout(changeRem, 300);
}
}, false);
}());
</script>
