在安卓机上 键盘弹起影响定位的弹框显示

原因：是因为安卓手机 键盘弹起屏幕的实际高度发生了变化 使定位的弹框位置发生了改变

解决办法：

描述：重点是改变高度

var winHeight = $(window).height(); //获取当前页面高度  
          $(window).resize(function() {  
              var thisHeight = $(this).height();

              console.log(thisHeight)
              console.log(winHeight)
            //   alert(thisHeight)
            //   alert(winHeight)
              let changeHeiNum = winHeight - thisHeight
              let div = document.getElementsByClassName("dataContents")[0];
            //   console.log(changeHeiNum)
              if (changeHeiNum > 50) {
                  //当软键盘弹出，在这里面操作  
                  div.style.height = "calc(70vh + 54px - "  + changeHeiNum/3 +"px)"
              } else {  
                  //alert('bbb');  
                  //当软键盘收起，在此处操作  
                 div.style.height = "calc(70vh + 54px)";
              }  
          });
