在进行了更多工作之后,我提出了一个简单但完整的示例来说明如何使用最新的 History.js。这是工作 jsfiddle 示例,它执行托管在 Github 上的 Ajax 加载HTML 片段

<p>The whole page will not re-load when the content below is updated, yet the URL is clean and the back button works!<p><br />
<div id="content">
<div id="home">Home Page content</div>
</div>
<br />
<p>The content div will be updated with a selected div fragment from an HTML file hosted on github, however the broswer will see each content update request as a part of the page history so that the back button can be used.</p>
<br />
<p>Adding more menu items is as simple as adding the new links and their corresponding html fragments.<p>
<div id="hidden_content" class="hidden"></div>
