input 获取和失去焦点时异常在安卓和ios平台处理

安卓平台处理

 //安卓机在键盘弹出后防止按钮顶上来
    mounted() {
      this.windowHclass=window.innerHeight<=480?"min": window.innerHeight<667?"active":(window.innerHeight>700?"actives":"");
 this.clientHeight=document.body.offsetHeight;
       var u = navigator.userAgent;
       if (u.indexOf('Android') > -1 || u.indexOf('Linux') > -1) {//安卓手机
        window.addEventListener("resize", this.handleResize);
        this.Android =true
       }
    }

    handleResize(){
        let nowHeight = document.body.offsetHeight;
        this.btnShow = nowHeight === this.clientHeight;//控制显示和隐藏按钮
        document.getElementById('home').style.height= (this.clientHeight-40)+'px'
      }

ios平台处理

 //ios在获取焦点后下面的空白隐藏
      blurfn() {
        let u = navigator.userAgent;
        if(u.indexOf('iPhone') > -1){
          window.scrollTo(0, this.clientHeight);
        }
      },
      focus() {
        let u = navigator.userAgent;
        if(u.indexOf('iPhone') > -1){
          window.scrollTo(0, 100);
        };
      },
