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?

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

使用ES6反撇号' ':模板文字!
let nick = "Castor"， name = "Moon"， nuts = 1 更多。innerHTML = ' <h1>Hello ${nick} ${name}!< / h1 > 到目前为止你收集了${nuts} nuts ! <人力资源> 加倍就能得到${坚果+坚果}坚果!! ｀ < div id = "更多" > < / div >
通过这种方式，我们可以在不编码引号的情况下包含html，包括来自DOM的变量，等等。
它是一个强大的模板引擎，我们可以使用单独的js文件和使用事件来加载内容，甚至将所有内容分成块并按需调用:
let inject = document.createElement('script');
inject.src= '//....com/template/panel45.js';
more.appendChild(inject);
https://caniuse.com/#feat=template-literals
好吧，如果你只是想把一个单独文件中的文本放到你的页面中(文本中的标签也应该可以工作)，你可以这样做(你在主页上的文本样式- test.html -应该仍然可以工作):
test.html
<html>
<body>
<p>Start</p>
<p>Beginning</p>
<div>
<script language="JavaScript" src="sample.js"></script>
</div>
<p>End</p>
</body>
</html>
sample.js
var data="Here is the imported text!";
document.write(data);
毕竟，您总是可以自己重新创建您想要的HTML标记。服务器端脚本只需要从另一个文件获取文本，除非您想做更多的事情。
无论如何，我开始使用这个是为了使它，所以如果我更新一个描述在许多HTML文件中，我只需要更新一个文件来做它(.js文件)，而不是每一个包含文本的HTML文件。
因此，总的来说，与其导入.html文件，更简单的解决方案是导入一个.js文件，并将.html文件的内容放在一个变量中(并将内容写入调用脚本的屏幕)。
谢谢你的问题。
这些解决方案都不适合我的需要。我在寻找更像php的东西。在我看来，这个解决方案非常简单有效。
include.js - - - >
void function(script) {
const { searchParams } = new URL(script.src);
fetch(searchParams.get('src')).then(r => r.text()).then(content => {
script.outerHTML = content;
});
}(document.currentScript);
index . html - - - >
<script src="/include.js?src=/header.html">
<main>
Hello World!
</main>
<script src="/include.js?src=/footer.html">
可以做一些简单的调整来创建include_once、require和require_once，它们可能都很有用，这取决于您正在做什么。下面是一个简短的例子。
include_once - - - >
var includedCache = includedCache || new Set();
void function(script) {
const { searchParams } = new URL(script.src);
const filePath = searchParams.get('src');
if (!includedCache.has(filePath)) {
fetch(filePath).then(r => r.text()).then(content => {
includedCache.add(filePath);
script.outerHTML = content;
});
}
}(document.currentScript);
希望能有所帮助!
不需要脚本。不需要做任何花哨的东西服务器端(尽管这可能是一个更好的选择)
<iframe src="/path/to/file.html" seamless></iframe>
由于旧的浏览器不支持无缝，你应该添加一些css来修复它:
iframe[seamless] {
border: none;
}
请记住，对于不支持无缝链接的浏览器，如果您单击iframe中的链接，它将使框架指向该url，而不是整个窗口。一种解决方法是让所有链接都有target="_parent"，尽管浏览器的支持是“足够好”。
I came to this topic looking for something similar, but a bit different from the problem posed by lolo. I wanted to construct an HTML page holding an alphabetical menu of links to other pages, and each of the other pages might or might not exist, and the order in which they were created might not be alphabetical (nor even numerical). Also, like Tafkadasoh, I did not want to bloat the web page with jQuery. After researching the problem and experimenting for several hours, here is what worked for me, with relevant remarks added:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/application/html; charset=iso-8859-1">
<meta name="Author" content="me">
<meta copyright="Copyright" content= "(C) 2013-present by me" />
<title>Menu</title>
<script type="text/javascript">
<!--
var F000, F001, F002, F003, F004, F005, F006, F007, F008, F009,
F010, F011, F012, F013, F014, F015, F016, F017, F018, F019;
var dat = new Array();
var form, script, write, str, tmp, dtno, indx, unde;
/*
The "F000" and similar variables need to exist/be-declared.
Each one will be associated with a different menu item,
so decide on how many items maximum you are likely to need,
when constructing that listing of them. Here, there are 20.
*/
function initialize()
{ window.name="Menu";
form = document.getElementById('MENU');
for(indx=0; indx<20; indx++)
{ str = "00" + indx;
tmp = str.length - 3;
str = str.substr(tmp);
script = document.createElement('script');
script.type = 'text/javascript';
script.src = str + ".js";
form.appendChild(script);
}
/*
The for() loop constructs some <script> objects
and associates each one with a different simple file name,
starting with "000.js" and, here, going up to "019.js".
It won't matter which of those files exist or not.
However, for each menu item you want to display on this
page, you will need to ensure that its .js file does exist.
The short function below (inside HTML comment-block) is,
generically, what the content of each one of the .js files looks like:
<!--
function F000()
{ return ["Menu Item Name", "./URLofFile.htm", "Description string"];
}
-->
(Continuing the remarks in the main menu.htm file)
It happens that each call of the form.appendChild() function
will cause the specified .js script-file to be loaded at that time.
However, it takes a bit of time for the JavaScript in the file
to be fully integrated into the web page, so one thing that I tried,
but it didn't work, was to write an "onload" event handler.
The handler was apparently being called before the just-loaded
JavaScript had actually become accessible.
Note that the name of the function in the .js file is the same as one
of the pre-defined variables like "F000". When I tried to access
that function without declaring the variable, attempting to use an
"onload" event handler, the JavaScript debugger claimed that the item
was "not available". This is not something that can be tested-for!
However, "undefined" IS something that CAN be tested-for. Simply
declaring them to exist automatically makes all of them "undefined".
When the system finishes integrating a just-loaded .js script file,
the appropriate variable, like "F000", will become something other
than "undefined". Thus it doesn't matter which .js files exist or
not, because we can simply test all the "F000"-type variables, and
ignore the ones that are "undefined". More on that later.
The line below specifies a delay of 2 seconds, before any attempt
is made to access the scripts that were loaded. That DOES give the
system enough time to fully integrate them into the web page.
(If you have a really long list of menu items, or expect the page
to be loaded by an old/slow computer, a longer delay may be needed.)
*/
window.setTimeout("BuildMenu();", 2000);
return;
}
//So here is the function that gets called after the 2-second delay
function BuildMenu()
{ dtno = 0; //index-counter for the "dat" array
for(indx=0; indx<20; indx++)
{ str = "00" + indx;
tmp = str.length - 3;
str = "F" + str.substr(tmp);
tmp = eval(str);
if(tmp != unde) // "unde" is deliberately undefined, for this test
dat[dtno++] = eval(str + "()");
}
/*
The loop above simply tests each one of the "F000"-type variables, to
see if it is "undefined" or not. Any actually-defined variable holds
a short function (from the ".js" script-file as previously indicated).
We call the function to get some data for one menu item, and put that
data into an array named "dat".
Below, the array is sorted alphabetically (the default), and the
"dtno" variable lets us know exactly how many menu items we will
be working with. The loop that follows creates some "<span>" tags,
and the the "innerHTML" property of each one is set to become an
"anchor" or "<a>" tag, for a link to some other web page. A description
and a "<br />" tag gets included for each link. Finally, each new
<span> object is appended to the menu-page's "form" object, and thereby
ends up being inserted into the middle of the overall text on the page.
(For finer control of where you want to put text in a page, consider
placing something like this in the web page at an appropriate place,
as preparation:
<div id="InsertHere"></div>
You could then use document.getElementById("InsertHere") to get it into
a variable, for appending of <span> elements, the way a variable named
"form" was used in this example menu page.
Note: You don't have to specify the link in the same way I did
(the type of link specified here only works if JavaScript is enabled).
You are free to use the more-standard "<a>" tag with the "href"
property defined, if you wish. But whichever way you go,
you need to make sure that any pages being linked actually exist!
*/
dat.sort();
for(indx=0; indx<dtno; indx++)
{ write = document.createElement('span');
write.innerHTML = "<a onclick=\"window.open('" + dat[indx][1] +
"', 'Menu');\" style=\"color:#0000ff;" +
"text-decoration:underline;cursor:pointer;\">" +
dat[indx][0] + "</a> " + dat[indx][2] + "<br />";
form.appendChild(write);
