h5软键盘问题

<script>$('input').on('focus',function(event){             //自动反弹 输入法高度自适应        var target = this;        setTimeout(function(){            target.scrollIntoViewIfNeeded();        },800);    });window.addEventListener("resize", function() {if($(".saveBtn").hasClass("cur")){$(".saveBtn").removeClass("cur")}else{$(".saveBtn").addClass("cur")}});</script>

.saveBtn{position: fixed;  bottom: 0;  left: 0;}.saveBtn.cur{position: static;}

再或者是让按钮上方的元素padding-bottom：元素的高度
