監(jiān)聽頁面中所有input輸入框箍铭，對焦點和失去焦點時做優(yōu)化判斷處理

let inputs = document.getElementsByTagName('input');
            let timer = null;
            for (let input of inputs) {
                input.addEventListener('blur', function() {
                    timer = setTimeout(() => {
                        window.scrollTo(0, 0);
                        timer = null;
                    }, 0);
                }, false);
                input.addEventListener('focus', function() {

                    timer && clearTimeout(timer);
                }, false);
            }

安卓手機頁面如果設置全屏粮彤，軟鍵盤彈起收回后，整體頁面會被壓縮柏靶；
全屏設置需要針對不同瀏覽器做判斷，否則ios或者安卓會不兼容溃论；
全屏插件---安卓適用

export default {
    install(Vue, options) {
        Vue.prototype.$screenFull = function () {
            let element = document.documentElement;
            console.log('全屏', this.fullscreen)
            if (this.fullscreen) {
                if (document.exitFullscreen) {
                    document.exitFullscreen();
                } else if (document.webkitCancelFullScreen) {
                    document.webkitCancelFullScreen();
                } else if (document.mozCancelFullScreen) {
                    document.mozCancelFullScreen();
                } else if (document.msExitFullscreen) {
                    document.msExitFullscreen();
                }
            } else {
                if (element.requestFullscreen) {
                    element.requestFullscreen();
                } else if (element.webkitRequestFullScreen) {
                    element.webkitRequestFullScreen();
                } else if (element.mozRequestFullScreen) {
                    element.mozRequestFullScreen();
                } else if (element.msRequestFullscreen) {
                    // IE11
                    element.msRequestFullscreen();
                }
            }
            this.fullscreen = !this.fullscreen;
            //this.isFullscreen = true
        }
    }
