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

不要脸的插头一个库,我写了解这个。

https://github.com/LexmarkWeb/csi.js

<div data-include="/path/to/include.html"></div>

上面的代码将获取/path/to/include.html的内容,并用它替换div。

其他回答

基于https://stackoverflow.com/a/31837264/4360308的回答 我用Nodejs (+ express + cheerio)实现了这个功能,如下所示:

HTML (index . HTML)

<div class="include" data-include="componentX" data-method="append"></div>
<div class="include" data-include="componentX" data-method="replace"></div>

JS

function includeComponents($) {
    $('.include').each(function () {
        var file = 'view/html/component/' + $(this).data('include') + '.html';
        var dataComp = fs.readFileSync(file);
        var htmlComp = dataComp.toString();
        if ($(this).data('method') == "replace") {
            $(this).replaceWith(htmlComp);
        } else if ($(this).data('method') == "append") {
            $(this).append(htmlComp);
        }
    })
}

function foo(){
    fs.readFile('./view/html/index.html', function (err, data) {
        if (err) throw err;
        var html = data.toString();
        var $ = cheerio.load(html);
        includeComponents($);
        ...
    }
}

Append ->将内容包含到div中

Replace ->替换div

您可以根据相同的设计轻松添加更多的行为

你可以用JavaScript的jQuery库来实现这一点,就像这样:

HTML:

<div class="banner" title="banner.html"></div>

JS:

$(".banner").each(function(){
    var inc=$(this);
    $.get(inc.attr("title"), function(data){
        inc.replaceWith(data);
    });
});

请注意banner.html应该位于您的其他页面所在的相同域下,否则您的网页将拒绝banner.html文件,因为跨源资源共享政策。

另外,请注意,如果您使用JavaScript加载内容,谷歌将无法对其进行索引,因此对于SEO而言,这并不是一个好方法。

Web组件

我创建了以下类似JSF的web组件

<ui-include src="b.xhtml"><ui-include>

你可以在你的页面中使用它作为常规的html标签(在包括snippet js代码之后)

customElements.define('ui-include', class extends HTMLElement { async connectedCallback() { let src = this.getAttribute('src'); this.innerHTML = await (await fetch(src)).text();; } }) ui-include { margin: 20px } /* example CSS */ <ui-include src="https://cors-anywhere.herokuapp.com/https://example.com/index.html"></ui-include> <div>My page data... - in this snippet styles overlaps...</div> <ui-include src="https://cors-anywhere.herokuapp.com/https://www.w3.org/index.html"></ui-include>

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)

在我看来,最好的解决方案使用jQuery:

a.html:

<html> 
  <head> 
    <script src="jquery.js"></script> 
    <script> 
    $(function(){
      $("#includedContent").load("b.html"); 
    });
    </script> 
  </head> 

  <body> 
     <div id="includedContent"></div>
  </body> 
</html>

b.html:

<p>This is my include file</p>

这个方法简单明了地解决了我的问题。
