移动端输入法挡住输入框

问题:在移动端火狐浏览下,输入框键盘遮挡住

解决方案:

  element.scrollIntoView():让元素滚动到可视区域
  参数:true 对象的顶端与当前窗口的顶部对齐
     false 对象的底端与当前窗口的顶部对齐

代码如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">

<style>
  input {
    width: 100%;
    line-height: 1.5rem;
    border: 1px solid red;
  }

  .block-fill {
    height: 500px;
  }  
</style>
</head>
<body>
  <div id="main">

     <div id="value"></div>
    <!--占位div-->
    <div class="block-fill"></div>
    <!--需要聚焦-->
    <input id="input" type="text"></input>
  </div>

</body>
<script>
window.onload=function(){
   //获取页面高度
    var clientHeight = document.body.clientHeight;
    var focusElem = document.getElementById('input');
    var valueElem = document.getElementById("value");

  //设置监听聚焦事件
  document.body.addEventListener("focus", function(e) {
    focusElem.scrollIntoView(false);
  }, true);
  
//设置监听窗口变化时间   window.addEventListener("resize", function() valueElem.innerHTML="focues resize:"+document.body.clientHeight+";screenHeight="+clientHeight;     if(focusElem && document.body.clientHeight < clientHeight) {     //使用scrollIntoView方法来控制输入框     focusElem.scrollIntoView(false);     }   });
}
</script>

</html>
