我知道这是一个非常老的帖子，所以一些方法在当时是不可用的。 但以下是我对它的简单看法(基于Lolo的回答)。

它依赖于HTML5的data-*属性，因此非常通用，因为它使用jQuery的for-each函数来获取每个匹配“load-html”的.class，并使用其各自的“data-source”属性来加载内容:

<div class="container-fluid">
    <div class="load-html" id="NavigationMenu" data-source="header.html"></div>
    <div class="load-html" id="MainBody" data-source="body.html"></div>
    <div class="load-html" id="Footer" data-source="footer.html"></div>
</div>
<script src="js/jquery.min.js"></script>
<script>
$(function () {
    $(".load-html").each(function () {
        $(this).load(this.dataset.source);
    });
});
</script>

插入指定文件的内容。

<!--#include virtual="filename.htm"-->

一个非常老的解决方案满足了我当时的需求，但下面是如何做到标准兼容的代码:

<!--[if IE]>
<object classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" data="some.html">
<p>backup content</p>
</object>
<![endif]-->

<!--[if !IE]> <-->
<object type="text/html" data="some.html">
<p>backup content</p>
</object>
<!--> <![endif]-->

如果你使用一些框架，比如django/bootle，他们通常会提供一些模板引擎。 假设您使用了bottle，默认的模板引擎是SimpleTemplate engine。 下面是纯html文件

$ cat footer.tpl
<hr> <footer>   <p>&copy; stackoverflow, inc 2015</p> </footer>

你可以包括页脚。TPL在你的主文件中，比如:

$ cat dashboard.tpl
%include footer

除此之外，您还可以将参数传递给dashboard .tpl。

html5rocks.com has a very good tutorial on this stuff, and this might be a little late, but I myself didn't know this existed. w3schools also has a way to do this using their new library called w3.js. The thing is, this requires the use of a web server and and HTTPRequest object. You can't actually load these locally and test them on your machine. What you can do though, is use polyfills provided on the html5rocks link at the top, or follow their tutorial. With a little JS magic, you can do something like this:

 var link = document.createElement('link');
 if('import' in link){
     //Run import code
     link.setAttribute('rel','import');
     link.setAttribute('href',importPath);
     document.getElementsByTagName('head')[0].appendChild(link);
     //Create a phantom element to append the import document text to
     link = document.querySelector('link[rel="import"]');
     var docText = document.createElement('div');
     docText.innerHTML = link.import;
     element.appendChild(docText.cloneNode(true));
 } else {
     //Imports aren't supported, so call polyfill
     importPolyfill(importPath);
 }

This will make the link (Can change to be the wanted link element if already set), set the import (unless you already have it), and then append it. It will then from there take that and parse the file in HTML, and then append it to the desired element under a div. This can all be changed to fit your needs from the appending element to the link you are using. I hope this helped, it may irrelevant now if newer, faster ways have come out without using libraries and frameworks such as jQuery or W3.js.

UPDATE:这将抛出一个错误，表示本地导入已被CORS策略阻塞。可能需要访问深层网络才能使用它，因为深层网络的特性。(意思是没有实际用途)

仅使用HTML是不可能将HTML文件包含在另一个HTML文件中。这里有一个很简单的方法。使用这个JS库你可以很容易地做到这一点。只需使用以下代码:

<script> include('path/to/file.html', document.currentScript) </script>
