我有2个HTML文件,假设a.html和b.html。在a.html中,我想包括b.html。

在JSF中,我可以这样做:

<ui:include src="b.xhtml" />

这意味着在.xhtml文件中,我可以包含b.xhtml。

我们如何在*.html文件中做到这一点?

另一种方法是使用Fetch API和Promise

<html>
 <body>
  <div class="root" data-content="partial.html">
  <script>
      const root = document.querySelector('.root')
      const link = root.dataset.content;

      fetch(link)
        .then(function (response) {
          return response.text();
        })
        .then(function (html) {
          root.innerHTML = html;
        });
  </script>
 </body>
</html>

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)

以下工作,如果html内容从一些文件需要包括: 例如,下面一行将在OBJECT定义出现的位置包含piece_to_include.html的内容。

...text before...
<OBJECT data="file_to_include.html">
Warning: file_to_include.html could not be included.
</OBJECT>
...text after...

参考:http://www.w3.org/TR/WD-html40-970708/struct/includes.html # h-7.7.4

下面是我使用Fetch API和async函数的方法

<div class="js-component" data-name="header" data-ext="html"></div>
<div class="js-component" data-name="footer" data-ext="html"></div>

<script>
    const components = document.querySelectorAll('.js-component')

    const loadComponent = async c => {
        const { name, ext } = c.dataset
        const response = await fetch(`${name}.${ext}`)
        const html = await response.text()
        c.innerHTML = html
    }

    [...components].forEach(loadComponent)
</script>

扩展lolo的回答,如果您必须包含很多文件,这里有更多的自动化。使用下面的JS代码:

$(function () {
  var includes = $('[data-include]')
  $.each(includes, function () {
    var file = 'views/' + $(this).data('include') + '.html'
    $(this).load(file)
  })
})

然后在html中包含一些东西:

<div data-include="header"></div>
<div data-include="footer"></div>

这将包括文件views/header.html和views/footer.html。

这是一篇很棒的文章,你可以实现公共库,只需使用下面的代码在一行中导入任何HTML文件。

<head>
   <link rel="import" href="warnings.html">
</head>
