這個(gè)問(wèn)題會(huì)導(dǎo)致頁(yè)面定位的按鈕會(huì)失靈，所以當(dāng)鍵盤(pán)消失后边臼，我們要想辦法將頁(yè)面拉下來(lái)哄尔，通過(guò)監(jiān)聽(tīng)鍵盤(pán)事件，來(lái)解決：
let keyTimer = null;
document.body.addEventListener('focusin', () => {
//軟鍵盤(pán)彈起事件
clearTimeout(keyTimer);
});
document.body.addEventListener('focusout', () => {
// 軟鍵盤(pán)關(guān)閉事件
window.scrollTo(0, 0);
keyTimer = setTimeout(() => {
if (window.pageYOffset > 0) {
window.scrollTo(0, 0);
}
}, 200);
});
