vue实现编辑器键盘抬起时内容跟随光标距顶位置向上滚动效果

let sel = window.getSelection();获取光标的所有属性

console.log(sel.getRangeAt(0).commonAncestorContainer.parentElement)

sel.getRangeAt(0).commonAncestorContainer.parentElement.parentNode.offsetTop

this.$nextTick(() => {
 dom.scrollTop = ket;
 });

let sel = window.getSelection();
let ket = sel.getRangeAt(0).commonAncestorContainer.parentElement.offsetTop;
if(ket==0){//行标签
 ket = sel.getRangeAt(0).commonAncestorContainer.parentElement.parentNode.offsetTop
}
 this.$nextTick(() => {
 dom.scrollTop = ket;
});

let ket = sel.getRangeAt(0).commonAncestorContainer.parentElement.offsetTop==0"color: #ff0000">总结
