在HTML文件中包含另一个HTML文件

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?

当前回答

您可以使用HTML Imports的填充(https://www.html5rocks.com/en/tutorials/webcomponents/imports/)或简化的解决方案 https://github.com/dsheiko/html-import

例如，在你导入HTML块的页面上:

<link rel="html-import" href="./some-path/block.html" >

该块可以有自己的导入:

<link rel="html-import" href="./some-other-path/other-block.html" >

导入器用加载的HTML替换指令，就像SSI一样

这些指令将在你加载这个小JavaScript时自动提供:

<script async src="./src/html-import.js"></script>

它将在DOM准备就绪时自动处理导入。此外，它还公开了一个API，您可以使用该API手动运行、获取日志等等。享受:)

其他回答

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。

我的解决方案类似于上面的lolo。但是，我通过JavaScript的文档插入HTML代码。编写而不是使用jQuery:

a.html:

<html> 
  <body>
  <h1>Put your HTML content before insertion of b.js.</h1>
      ...

  <script src="b.js"></script>

      ...

  <p>And whatever content you want afterwards.</p>
  </body>
</html>

研究:

document.write('\
\
    <h1>Add your HTML code here</h1>\
\
     <p>Notice however, that you have to escape LF's with a '\', just like\
        demonstrated in this code listing.\
    </p>\
\
');

我反对使用jQuery的原因是jQuery.js的大小约为90kb，我想保持加载的数据量尽可能小。

为了得到正确转义的JavaScript文件，你可以使用下面的sed命令:

sed 's/\\/\\\\/g;s/^.*$/&\\/g;s/'\''/\\'\''/g' b.html > escapedB.html

或者只是使用以下方便的bash脚本作为Github上的Gist发布，它自动完成所有必要的工作，将b.html转换为b.js: https://gist.github.com/Tafkadasoh/334881e18cbb7fc2a5c033bfa03f6ee6

感谢Greg Minshall改进的sed命令，它还转义了反斜杠和单引号，这是我最初的sed命令没有考虑到的。

另外，对于支持模板字面量的浏览器，以下方法也适用:

研究:

document.write(`

    <h1>Add your HTML code here</h1>

     <p>Notice, you do not have to escape LF's with a '\',
        like demonstrated in the above code listing.
    </p>

`);

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)

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>

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
