更新:根据SearchEngineLand上的评论和参考 大多数网络爬虫将索引更新的标题。下面的答案是过时的，但代码仍然适用。

You can just do something like, document.title = "This is the new page title.";, but that would totally defeat the purpose of SEO. Most crawlers aren't going to support javascript in the first place, so they will take whatever is in the element as the page title. If you want this to be compatible with most of the important crawlers, you're going to need to actually change the title tag itself, which would involve reloading the page (PHP, or the like). You're not going to be able to get around that, if you want to change the page title in a way that a crawler can see.

代码是 文档。Title = 'test'

为了让任何爬虫程序注意到这个变化，您必须用一个新的标题重新提供页面。通过javascript这样做只会让人类读者受益，爬虫不会执行这些代码。

想到的一种方法，可能有助于搜索引擎优化，仍然有你的标签页，因为他们将使用命名锚对应于每个标签，如:

http://www.example.com/mypage#tab1, http://www.example.com/mypage#tab2等。

您需要服务器端处理来解析url，并在浏览器呈现页面时设置初始页面标题。我还会把这个标签设置为“活动”标签。一旦页面被加载，一个实际的用户正在切换标签，你将使用javascript来改变文档。标题如其他用户所述。

对于那些寻找它的NPM版本的人，有一个完整的库:

npm install --save react-document-meta

import React from 'react';
import DocumentMeta from 'react-document-meta';

class Example extends React.Component {
  render() {
    const meta = {
      title: 'Some Meta Title',
      description: 'I am a description, and I can create multiple tags',
      canonical: 'http://example.com/path/to/page',
      meta: {
        charset: 'utf-8',
        name: {
          keywords: 'react,meta,document,html,tags'
        }
      }
    };

    return (
      <div>
        <DocumentMeta {...meta} />
        <h1>Hello World!</h1>
      </div>
    );
  }
}

React.render(<Example />, document.getElementById('root'));

也许你可以在一个字符串中加载你的标题上所有的选项卡标题，然后一旦你加载其中一个选项卡，通过javascript改变标题

首先把你的标题设置为

my app | description | contact | about us | 

一旦你加载一个标签运行:

document.title = "my app | tab title";
