javascript - ReactJS - ReactMount : Root element has been removed from its original container. 新容器

Question

这个错误是什么意思？如何解决？

ReactMount: Root element has been removed from its original container. New container

在这之后我得到了这个:

当我遇到这些问题时，我会尝试使用新的项目列表来更新我的 View 。要更新我当前的 View ，我调用 updatePosts():

var updatePosts = function () {
    var content = document.querySelector('.content');
    content.innerHTML = '';
    $refresh.addClass('fa-spin');
    return React.renderComponent(
        <Posts />,
        content
    );
};

会不会是这个 innerHTML = '' 的问题？我将再次完整呈现我的 Posts 组件。

Answer 1

删除这一行

content.innerHTML = '';

React 将查看旧的虚拟 dom，以及 <Posts /> 返回的内容(与 Posts() 相同)。它将比较它们，并对 DOM 进行所需的更新。
