I have 2 HTML files, suppose a.html and b.html. In a.html I want to include b.html.
In JSF I can do it like that:
<ui:include src="b.xhtml" />
It means that inside a.xhtml file, I can include b.xhtml.
How can we do it in *.html file?
In my opinion the best solution uses 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>
This method is a simple and clean solution to my problem.
The jQuery .load() documentation is here.
Expanding lolo's answer, here is a little more automation if you have to include a lot of files. Use this JS code:
$(function () {
var includes = $('[data-include]')
$.each(includes, function () {
var file = 'views/' + $(this).data('include') + '.html'
$(this).load(file)
})
})
And then to include something in the html:
<div data-include="header"></div>
<div data-include="footer"></div>
Which would include the file views/header.html and views/footer.html.
My solution is similar to the one of lolo above. However, I insert the HTML code via JavaScript's document.write instead of using jQuery:
a.html:
<html>
<body>
<h1>Put your HTML content before insertion of b.js.</h1>
...
<script src="b.js"></script>
...
<p>And whatever content you want afterwards.</p>
</body>
</html>
b.js:
document.write('\
\
<h1>Add your HTML code here</h1>\
\
<p>Notice however, that you have to escape LF's with a '\', just like\
demonstrated in this code listing.\
</p>\
\
');
The reason for me against using jQuery is that jQuery.js is ~90kb in size, and I want to keep the amount of data to load as small as possible.
In order to get the properly escaped JavaScript file without much work, you can use the following sed command:
sed 's/\\/\\\\/g;s/^.*$/&\\/g;s/'\''/\\'\''/g' b.html > escapedB.html
Or just use the following handy bash script published as a Gist on Github, that automates all necessary work, converting b.html to b.js:
https://gist.github.com/Tafkadasoh/334881e18cbb7fc2a5c033bfa03f6ee6
Credits to Greg Minshall for the improved sed command that also escapes back slashes and single quotes, which my original sed command did not consider.
Alternatively for browsers that support template literals the following also works:
b.js:
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>
`);
Checkout HTML5 imports via Html5rocks tutorial
and at polymer-project
For example:
<head>
<link rel="import" href="/path/to/imports/stuff.html">
</head>
Shameless plug of a library that I wrote the solve this.
https://github.com/LexmarkWeb/csi.js
<div data-include="/path/to/include.html"></div>
The above will take the contents of /path/to/include.html and replace the div with it.
No need for scripts. No need to do any fancy stuff server-side (tho that would probably be a better option)
<iframe src="/path/to/file.html" seamless></iframe>
Since old browsers don't support seamless, you should add some css to fix it:
iframe[seamless] {
border: none;
}
Keep in mind that for browsers that don't support seamless, if you click a link in the iframe it will make the frame go to that url, not the whole window. A way to get around that is to have all links have target="_parent", tho the browser support is "good enough".
A simple server side include directive to include another file found in the same folder looks like this:
<!--#include virtual="a.html" -->
Also you can try:
<!--#include file="a.html" -->
A very old solution I did met my needs back then, but here's how to do it standards-compliant code:
<!--[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]-->
Following works if html content from some file needs to be included:
For instance, the following line will include the contents of piece_to_include.html at the location where the OBJECT definition occurs.
...text before...
<OBJECT data="file_to_include.html">
Warning: file_to_include.html could not be included.
</OBJECT>
...text after...
Reference: http://www.w3.org/TR/WD-html40-970708/struct/includes.html#h-7.7.4
Here is my inline solution:
(() => {
const includes = document.getElementsByTagName('include');
[].forEach.call(includes, i => {
let filePath = i.getAttribute('src');
fetch(filePath).then(file => {
file.text().then(content => {
i.insertAdjacentHTML('afterend', content);
i.remove();
});
});
});
})();
<p>FOO</p>
<include src="a.html">Loading...</include>
<p>BAR</p>
<include src="b.html">Loading...</include>
<p>TEE</p>
In w3.js include works like this:
<body>
<div w3-include-HTML="h1.html"></div>
<div w3-include-HTML="content.html"></div>
<script>w3.includeHTML();</script>
</body>
For proper description look into this: https://www.w3schools.com/howto/howto_html_include.asp
As an alternative, if you have access to the .htaccess file on your server, you can add a simple directive that will allow php to be interpreted on files ending in .html extension.
RemoveHandler .html
AddType application/x-httpd-php .php .html
Now you can use a simple php script to include other files such as:
<?php include('b.html'); ?>
This is what helped me. For adding a block of html code from b.html to a.html, this should go into the head tag of a.html:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Then in the body tag, a container is made with an unique id and a javascript block to load the b.html into the container, as follows:
<div id="b-placeholder">
</div>
<script>
$(function(){
$("#b-placeholder").load("b.html");
});
</script>
I know this is a very old post, so some methods were not available back then.
But here is my very simple take on it (based on Lolo's answer).
It relies on the HTML5 data-* attributes and therefore is very generic in that is uses jQuery's for-each function to get every .class matching "load-html" and uses its respective 'data-source' attribute to load the content:
<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>
Most of the solutions works but they have issue with jquery:
The issue is following code $(document).ready(function () { alert($("#includedContent").text()); } alerts nothing instead of alerting included content.
I write the below code, in my solution you can access to included content in $(document).ready function:
(The key is loading included content synchronously).
index.htm:
<html>
<head>
<script src="jquery.js"></script>
<script>
(function ($) {
$.include = function (url) {
$.ajax({
url: url,
async: false,
success: function (result) {
document.write(result);
}
});
};
}(jQuery));
</script>
<script>
$(document).ready(function () {
alert($("#test").text());
});
</script>
</head>
<body>
<script>$.include("include.inc");</script>
</body>
</html>
include.inc:
<div id="test">
There is no issue between this solution and jquery.
</div>

You can use a polyfill of HTML Imports (https://www.html5rocks.com/en/tutorials/webcomponents/imports/), or that simplified solution
https://github.com/dsheiko/html-import
For example, on the page you import HTML block like that:
<link rel="html-import" href="./some-path/block.html" >
The block may have imports of its own:
<link rel="html-import" href="./some-other-path/other-block.html" >
The importer replaces the directive with the loaded HTML pretty much like SSI
These directives will be served automatically as soon as you load this small JavaScript:
<script async src="./src/html-import.js"></script>
It will process the imports when DOM is ready automatically. Besides, it exposes an API that you can use to run manually, to get logs and so on. Enjoy :)
Here's my approach using Fetch API and async function
<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>
To insert contents of the named file:
<!--#include virtual="filename.htm"-->
Another approach using Fetch API with 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>
Did you try a iFrame injection?
It injects the iFrame in the document and deletes itself (it is supposed to be then in the HTML DOM)
<iframe src="header.html" onload="this.before((this.contentDocument.body||this.contentDocument).children[0]);this.remove()"></iframe>
Regards
The Athari´s answer (the first!) was too much conclusive! Very Good!
But if you would like to pass the name of the page to be included as URL parameter, this post has a very nice solution to be used combined with:
http://www.jquerybyexample.net/2012/06/get-url-parameters-using-jquery.html
So it becomes something like this:
Your URL:
www.yoursite.com/a.html?p=b.html
The a.html code now becomes:
<html>
<head>
<script src="jquery.js"></script>
<script>
function GetURLParameter(sParam)
{
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++)
{
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam)
{
return sParameterName[1];
}
}
}
$(function(){
var pinc = GetURLParameter('p');
$("#includedContent").load(pinc);
});
</script>
</head>
<body>
<div id="includedContent"></div>
</body>
</html>
It worked very well for me!
I hope have helped :)
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: This will throw an error saying that the local import has been blocked by CORS policy. Might need access to the deep web to be able to use this because of the properties of the deep web. (Meaning no practical use)
Use includeHTML (smallest js-lib: ~150 lines)
Loading HTML parts via HTML tag (pure js)
Supported load: async/sync, any deep recursive includes
Supported protocols: http://, https://, file:///
Supported browsers: IE 9+, FF, Chrome (and may be other)
USAGE:
1.Insert includeHTML into head section (or before body close tag) in HTML file:
<script src="js/includeHTML.js"></script>
2.Anywhere use includeHTML as HTML tag:
<div data-src="header.html"></div>
There is no direct HTML solution for the task for now. Even HTML Imports (which is permanently in draft) will not do the thing, because Import != Include and some JS magic will be required anyway.
I recently wrote a VanillaJS script that is just for inclusion HTML into HTML, without any complications.
Just place in your a.html
<link data-wi-src="b.html" />
<!-- ... and somewhere below is ref to the script ... -->
<script src="wm-html-include.js"> </script>
It is open-source and may give an idea (I hope)
You can do that with JavaScript's library jQuery like this:
HTML:
<div class="banner" title="banner.html"></div>
JS:
$(".banner").each(function(){
var inc=$(this);
$.get(inc.attr("title"), function(data){
inc.replaceWith(data);
});
});
Please note that banner.html should be located under the same domain your other pages are in otherwise your webpages will refuse the banner.html file due to Cross-Origin Resource Sharing policies.
Also, please note that if you load your content with JavaScript, Google will not be able to index it so it's not exactly a good method for SEO reasons.
Web Components
I create following web-component similar to JSF
<ui-include src="b.xhtml"><ui-include>
You can use it as regular html tag inside your pages (after including snippet js code)
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>
None of these solutions suit my needs. I was looking for something more PHP-like. This solution is quite easy and efficient, in my opinion.
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">
Simple tweaks can be made to create include_once, require, and require_once, which may all be useful depending on what you're doing. Here's a brief example of what that might look like.
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);
Hope it helps!
Here is a great article, You can implement common library and just use below code to import any HTML files in one line.
<head>
<link rel="import" href="warnings.html">
</head>
You can also try Google Polymer
To get Solution working you need to include the file csi.min.js, which you can locate here.
As per the example shown on GitHub, to use this library you must include the file csi.js in your page header, then you need to add the data-include attribute with its value set to the file you want to include, on the container element.
Hide Copy Code
<html>
<head>
<script src="csi.js"></script>
</head>
<body>
<div data-include="Test.html"></div>
</body>
</html>
... hope it helps.
There are several types of answers here, but I never found the oldest tool in the use here:
"And all the other answers didn't work for me."

I've already tested this code manually adding the backslash to all the </script> tags, and
if all the tags become <\/script> the code works.
var iframe = document.createElement('iframe');
var html = '<html><head><script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.js"><\/script><script type="text/javascript">$(window).load(function(){function popo1(){alert("ciaoooo!");}popo1();$(".eccolo").html("<br><br><br><br>xD sygsyusgsuygsus ysg usygsuys");});<\/script></head><body><div class="eccolo"></div></body></html>';
document.body.appendChild(iframe);
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(html);
iframe.contentWindow.document.close();
DEMO
But I need to dynamically auto-replace all the </script> tags with <\/script> using something like
XXX.replace(/<\/script>/ig, "<\\\/script>");
according to this post
but seems that this type of replace is actually not working...
var iframe = document.createElement('iframe');
var XXX = '<html><head><script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.js"><\/script><script type="text/javascript">$(window).load(function(){function popo1(){alert("ciaoooo!");}popo1();$(".eccolo").html("<br><br><br><br>xD sygsyusgsuygsus ysg usygsuys");});<\/script></head><body><div class="eccolo"></div></body></html>';
var YYY = XXX.replace(/<\/script>/ig, "<\\\/script>");
document.body.appendChild(iframe);
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(YYY);
iframe.contentWindow.document.close();
DEMO
Unfortunately I can't use .js files, so I hope that there is a way to properly do the tags replace
But what if I want to dynamically replace all the </script> tags with <\/script>...
In a comment below, you've said:
I'm getting the var XXX from an input that always changes.. I just added a defined value (var XXX='<html><head>...) in my question just for example
That's a very different thing than what's in your question. If you're saying that you'll receive input in the XXX string whose content (in memory, not a string literal) looks like this:
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.js"></script>
<script type="text/javascript">
$(window).load(function() {
function popo1() {
alert("ciaoooo!");
}
popo1();
$(".eccolo").html("<br><br><br><br>xD sygsyusgsuygsus ysg usygsuys");
});
</script>
</head>
<body>
<div class="eccolo"></div>
</body>
</html>
...then than input is perfectly fine and can be used as-is to set the content of the iframe. You don't have to do the replacement on it. The post you linked to doesn't relate to what you're doing.
But if you're saying you'll get input like this:
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.js"></script>
<script type="text/javascript">
$(window).load(function() {
var str = "The problem is here: </script>"; // <======
});
</script>
</head>
<body>
<div class="eccolo"></div>
</body>
</html>
...then you're in the same unfortunate position as the HTML parser: You don't know when the substring </script> actually ends a script element, or is text within a JavaScript string literal (or a comment). If you had a web page with that content, the HTML parser would conclude the script element ended immediately after The problem is here:. And indeed, if you output that content to an iframe via document.write, the parser will choke on it. The line:
var str = "The problem is here: </script>";
needs to be
var str = "The problem is here: <\/script>";
// or
var str = "The problem is here: </sc" + "ript>";
// or similar
...in order to avoid tripping up the HTML parser. (It would be fine in a .js file, but that's not your use case.)
Fundamentally, if you're receiving input with something like that in it, the person giving it to you is giving you invalid input. The substring </script> cannot appear in JavaScript code within <script>/</script> tags — not in a string literal, not in a comment, nowhere.
The answer defined by the spec is: Don't try to figure it out, require that it be correct. But if you know the scripts are JavaScript, and you really really want to allow invalid input and correct it, you'll need a JavaScript parser. That sounds outrageous, but Esprima is exactly that, there's jsparser in the Meteor stuff, and there may be others. You'd scan the string you're given to find <script>, then let the JavaScript parser take over and parse the code (you'll probably need to modify it so it knows to stop in </script> outside of a string literal / comment). Then take the text consumed by the parser, use your replace to convert any </script> in the code's text to <\/script>, and continue on.
It's non-trivial, which is why the spec doesn't require HTML parsers to do it.
But again, if the input is like your example in your question (without the backslashes you used to avoid this problem with your string literal), you don't have to do a replace at all. Just output it to the iframe, and it will work fine.
You can create script tag programatically and append in the head tag after page is loaded.
Following is the code and DEMO
var iframe = document.createElement('iframe');
var html = '<html><head></head><body><div class="eccolo"></div></body></html>';
document.body.appendChild(iframe);
iframe.contentWindow.document.open();
iframe.contentWindow.document.write(html);
var script1 = iframe.contentWindow.document.createElement('script');
var script2 = iframe.contentWindow.document.createElement('script');
script2.textContent = '$(window).load(function(){function popo1(){alert("ciaoooo!");}popo1();$(".eccolo").html("<br><br><br><br>xD sygsyusgsuygsus ysg usygsuys");});'
var head = iframe.contentWindow.document.querySelector('head');
head.appendChild(script1);
script1.onload = function() {
head.appendChild(script2);
}
script1.src = 'http://code.jquery.com/jquery-1.11.0.js';
iframe.contentWindow.document.close();
Hope it helps...
Here's what I'm trying to do;
I have this HTML code:
<div id="background-color-random">
DIV CONTENT
</div>
And this javascript:
$(document).ready(function() {
var colors = ["#FFA347", "#FF5050", "#FF66FF", "#6699FF", "#00FF99"],
selectedColor = colors[Math.floor(Math.random()*colors.length)]
header = $("div#background-color-random");
header.css("background-color", selectedColor);
});
I want to impliment this on an HTML page. I know that you can load up a *.js file by using the script tags with src="..". But that doesn't seem to work.
The javascript creates a random color and then applies that to the background of a given 'div' in the HTML.
Now, I'm not good with javascript, so please be patient with me and simple answers are needed :)
I need to be able to get the javascript to load when requested from the HTML and then apply itself to the div with id="..".
You have a syntax error (missing a comma):
selectedColor = colors[Math.floor(Math.random()*colors.length)]
header = $("div#background-color-random");
Should be
selectedColor = colors[Math.floor(Math.random()*colors.length)],
header = $("div#background-color-random");
You are using jQuery, not pure javascript. That's a good thing...
but you also must add the jQuery library in your head tags, like this:
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
</head>
You also need to put semi-colons (or commas, as RobM has corrected me, if between var assignments) at the end of each instruction. See line 3 in your code example.
If you want your js/jQuery code in a separate file, you can load the script code like this (again, usually done in the <head> tags):
<script src="filename.js" type="text/javascript"></script>
Or, you can include the js/jQ in the <head> tags of your document, like this:
<script type="text/javascript">
$(document).ready(function() {
var colors = ["#FFA347", "#FF5050", "#FF66FF", "#6699FF", "#00FF99"],
selectedColor = colors[Math.floor(Math.random()*colors.length)],
header = $("div#background-color-random");
header.css("background-color", selectedColor);
});
</script>
If including the script as an external file, you leave out the <script></script> wrapper from that file.
