ant-design-vue中树组件回显滚动定位

 

首先需要展开所选中的子节点所在的父级，即this.expandedKeys.push(curId）；

获取所选中的子节点事件，即可。

this.$nextTick(()=>{
        setTimeout(()=>{ 
          this.expandedKeys.push(curId)
        },500)
        setTimeout(() => {
          if(document.getElementsByClassName('ant-tree-treenode-checkbox-checked').length>0){
            document.getElementsByClassName('ant-tree-treenode-checkbox-checked')[0].scrollIntoView()
          }
          if(document.getElementsByClassName('ant-tree-treenode-selected').length>0){
            document.getElementsByClassName('ant-tree-treenode-selected')[0].scrollIntoView()
          }
        }, 1000);
      })
