ReactJS findDOMNode和getDOMNode不是函数

Question

我正在使用ReactJS和Flux构建一个Web应用程序,我正在尝试使用findDOMNode方法获取当前div的节点,我 得到下一个错误:

Uncaught TypeError: React.findDOMNode is not a function

所以,我尝试使用getDOMNode,我得到了同样的错误:

Uncaught TypeError: React.getDOMNode is not a function

我正在使用npm构建JS,我使用这些方法的代码:

var React = require('react');
var stores = require('../stores');
var MessagesUserContainer = require('./messageusercontainer');
var ChatStore = stores.ChatStore;
var owner = stores.getOwner();

var MessagesList = React.createClass({

    getInitialState: function(){
        return {'muc': []};
    },
    componentDidUpdate: function(){
        var node = React.findDOMNode(this); //Error here
        node.scrollTop = node.scrollHeight;
    },
    render: function(){
        return (
                <div className="chatScroll">
                    {this.state.muc}
                </div>
            )
    }
});

module.exports = MessagesList;

ReactJS verion:0.14.0

编辑

正如答案中所指出的,从v0.14.0开始的DOM库不在React核心中,因此我对我的代码进行了一些更改:

var React = require('react');
var ReactDOM = require('react-dom');
var stores = require('../stores');
var MessagesUserContainer = require('./messageusercontainer');
var ChatStore = stores.ChatStore;
var owner = stores.getOwner();

var MessagesList = React.createClass({

    getInitialState: function(){
        return {'muc': []};
    },
    componentDidUpdate: function(){
        var node = ReactDOM.findDOMNode(this);
        node.scrollTop = node.scrollHeight;
    },
    render: function(){
        return (
                <div className="chatScroll">
                    {this.state.muc}
                </div>
            )
    }
});

module.exports = MessagesList;

但我有另一个问题:

Uncaught Error: Invariant Violation: findDOMNode was called on an unmounted component.

在最新的React中更改:

ReactDOM.findDOMNode

https://facebook.github.io/react/docs/top-level-api.html#reactdom.finddomnode

它在react-dom包中.请注意,ReactDOMServer也已移至另一个包中.可能正在为React相关的特定于平台的API(例如React native)做准备.
