To override the chrome web store new tab page I use the following code:
"chrome_url_overrides": {
"newtab": "index.html"
}
I have a backend which serves the html files so instead of using the index.html file I would like to get a html file via a http request.
Is this possible? Or is there a workaround Thanks.
You could make an ajax call from your index page to remote server, and replace the entire html with external html. Sample code looks like the following
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<script src="index.js"></script>
</body>
</html>
index.js
var SERVER_URL = "";
var xhr = new XMLHttpRequest();
xhr.onload = function() {
replaceHtml(xhr.responseText);
};
xhr.open("GET", SERVER_URL);
xhr.send();
function replaceHtml(data) {
document.open("text/html");
document.write(data);
document.close();
}
You could simply have some javascript inside a <script></script> tag in your index.html file that grabs your generated html content from a custom domain.

I have an ASP.NET Core 6 app and I host my Angular app with it, among other things (from Program.cs):
...
app.Use(async (context, next) =>
{
RewriteXFrameOptionsHeader(context);
await next();
if (context.Response.StatusCode == 404 && !Path.HasExtension(context.Request.Path.Value))
{
context.Request.Path = "/";
await next();
}
});
app.UseDefaultFiles(new DefaultFilesOptions {DefaultFileNames = new List<string> {"index.html"}});
app.UseStaticFiles();
...
It it doesn't work, because scripts are not loaded. The Angular index.html uses base href and relative paths to js sources, like so:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<base href="/ngxapp">
...
<script src="runtime.7cef1b4acdcbe752.js" type="module"></script><script src="polyfills.e4b5afbd657fbe4a.js" type="module"></script><script src="main.c8a9bcf210ef6760.js" type="module"></script>
</body>
</html>
Even though script src's contain relative paths, the browser tries to load script from the root. Here's what dev tools Network tab shows:
Request URL: https://localhost:7101/runtime.7cef1b4acdcbe752.js
MDN docs for base href state:
The HTML element specifies the base URL to use for all relative URLs in a document.
Why then scripts are being loaded from root?
I'd like to use a style sheet from Wikipedia. For that, I'm fetching this style sheet. When trying to
pass the url fetched using ajax to the head of my html document, the url retrieved behave unexpectedly.
First, I simply try to use the url as it is fetched :
var stylesheetElem = doc.querySelector('head link[rel="stylesheet"]');
Here is the full code :
<!DOCTYPE html>
<!-- testing purpose file, used for trying to print a correctly formatted wikipedia page -->
<html>
<head>
<meta charset="utf-8"/>
<title> game setup </title> <!-- Titre de l'onglet -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
</head>
<body style="background-color:white;">
<div class='container'>
<h1 id="title">MiniWiki</h1>
<div id="content"></div>
</div>
<script>
function loadPage() {
"use strict";
var url, doc;
console.log("IN LOADPAGE")
url = 'https://en.wikipedia.org:443/api/rest_v1/page/html/' + 'Ancient_Egypt';
// fetch the article data
return $.ajax(url).then(function (data) {
doc = (new DOMParser()).parseFromString(data, 'text/html');
// Use mediawiki content stylesheet
var stylesheetElem = doc.querySelector('head link[rel="stylesheet"]');
console.log("SHOW stylesheetElem");
console.log(stylesheetElem);
$('head').append(stylesheetElem);
//Update content
var contentElem = document.getElementById('content');
var $content = $(contentElem).empty();
Array.from(doc.body.attributes).forEach(function (attr) {
$content.attr(attr.name, attr.value);
});
$content.append(Array.from(doc.body.children));
});
}
loadPage();
</script>
In this case, the url fetched is
<link rel="stylesheet" href="/w/load.php?lang=en&modulening.con...%7Cext.cite.styles&only=styles&skin=vector">
I was expecting that it would also include https://en.wikipedia.org/ at the beginning of the url like this :
<link rel="stylesheet" href="https://en.wikipedia.org/w/load.php?lang=en&modulening.con...%7Cext.cite.styles&only=styles&skin=vector">
Since it dit not, I thought I could add it myself by simply adding this line of code just
before the line
console.log("SHOW stylesheetElem");
stylesheetElem.href = "http://en.wikipedia.org" + stylesheetElem.href
when printing the stylesheetElem url, this unexpectedly returns the following url :
http://en.wikipedia.orgfile//en.wikipedia.org/w/load.php?...kin=vector
What happened here ? Why didn't I get the following correct url ?
http://en.wikipedia.org/w/load.php?...kin=vector
The dots (...) indicate that the developer tools have left out part of the url. You copy that instead of the real url, which you can see when you do "View Page Source":
/w/load.php?lang=en&modules=ext.uls.interlanguage%7Cext.visualEditor.desktopArticleTarget.noscript%7Cext.wikimediaBadges%7Cskins.vector.styles.legacy&only=styles&skin=vector
I used window.print() function and saved to a .pdf file.
Inside the page I've saved there is a <a href="www.example.com"> tag. When I'm downloading the file from Chrome the link works and it opens the right page. When downloading it from Edge it won't work and stays as a simple text.
Any solution?
I tested and reproduced the issue. I think we can only use some plugins to generate the pdf to get the href link working in Edge Legacy.
You could use jsPDF to generate the PDF. Use .textWithLink() to mimic standard HTML hyperlinks:
doc.textWithLink(text, x, y, { url: url });
Sample code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/jspdf/1.3.4/jspdf.debug.js"></script>
</head>
<body>
<script>
var doc = new jsPDF('p', 'pt');
doc.textWithLink('link', 20, 30, { url: 'http://www.google.com' });
doc.save("info.pdf");
</script>
</body>
</html>
I'm working on a project in which I have a simple web server hosted with node.js (see code below) and I want to be able to dynamically load the code form html files and modify them each time someone makes a request. I've already putted some marker in my code ${likeThis} and I just need the code to put a string in the right place.
Here is my server code:
const express = require('express');
const app = express();
app.get('/', function (req, res) {
res.send('Hello World');
})
app.listen(8080);
});
And here is an example page in which I want to change the value ${sampleText} with the plain text "hello world!!!":
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<head>
<title>Titler</title>
</head>
<body>
${sampleText}
</body>
Mind that there might be more of the same or different kind of value all over the html page.
On the user side I'd expect this:
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<head>
<title>Titler</title>
</head>
<body>
Hello world!!!
</body>
There are several ways to use live data in pages returned from express. All of them utilize a "template" into which you inject "data". These include:
pug
mustache
handlebars
Another option would be to use NodeJS/ES6 template strings, such as:
const express = require('express')
const app = express()
// Text to insert into template
const sampleText = 'hello world!!!'
// Template to accept sampleText
const result = `<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Titler</title>
</head>
<body>
${sampleText}
</body>
</html>
`
app.get('/', function (req, res) {
res.send(result);
})
app.listen(8080);
Backticks ("`") are used to define template strings in Node where "${expression}" is used to insert any evaluable JavaScript expression into a template, like:
const result = `The contents of file ${filepath} are: ${fs.readFileSync(filepath).toString()}`
For more information, see Using Template Engines with Express
and for an exhaustive list of template engines that work "out of the box" with Express see Template Engines
i ll illustrate with Mustache, you need webpack for communication between front-side and web-server, but since webpack is headache i ll use mustache CDN.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Document</title>
</head>
<body>
<div id="message"></div>
//we are gonna render the message into this div tag.
//this is a javascript code
//make sure script tags are at the bottom
<script id="message-template" type="text/html">
<div class="message">
{{message}} . //yes double curly brackets
</div>
</script>
//CDN link, Mustache pack files are stored here and we import from there
<script src="https://cdnjs.cloudflare.com/ajax/libs/mustache.js/3.0.1/mustache.min.js"></script>
//for src add path of index.js in your app
<script src="./index.js"></script>
</body>
</html>
index.js
//select the div that you wanna place the message
const $message = document.querySelector("#messages");
//select the script tag in
const messageTemplate = document.querySelector("#message-template").innerHTML;
const html = Mustache.render(messageTemplate, {
//I hardcoded the message here, but as you learn, you will catch a dynamic data, put it here and display in your html page
message:"hello world",
});
$message.innerHTML(html);
After a bit of work(very flew actualy) i monaged to make this function that allows me to find the strings and replace them with the correct text, i will publish it hoping someone else in the future migth need it:
function substituteString(input, stringToChange, substitute) {
var n = 0;
while (true) {
n = input.indexOf(stringToChange, n);
if (n == -1) { break; } else {
input = input.replace(stringToChange ,substitute);
}
}
return input;
}
Easier than i was thinking
I have file named a.html with this code:
<!DOCTYPE html>
<html lang="en-US">
<head>

<meta charset="utf-8" />
<meta name="generator" content="iloapp 2.1"/>
<link rel="shortcut icon" href="//ilostatic.one.com/iloapp/gallery/images/favicon.ico" type="image/vnd.microsoft.icon"/>
</head>
<body>
<script>
(function () {
var script = document.createElement('script');
script.src = '//ilostatic.one.com/iloapp/gallery/js/init.js?' + (new Date).getTime();
document.documentElement.firstChild.appendChild(script);
})();
</script>
<noscript><iframe src="//ilostatic.one.com/iloapp/gallery/html/nojs_1_en-US.html" frameBorder="0" style="position: absolute; left: 0px; top: 0px; width: 100%; height: 100%;"></iframe></noscript>
</body>
</html>
It`s for a galerie who look like this: link
I want to include this here: link
Need some help here.
If you are using Jquery you can do the following:
<html>
<head>
<script src="jquery.js"></script>
<script>
$(function(){
$("#includedContent").load("b.html");
});
</script>
</head>
<body>
<div id="includedContent"></div>
</body>
</html>
If you are looking to do raw Javascript DOM then you can do the following:
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
document.getElementById("demo").innerHTML = xhttp.responseText;
}
}
xhttp.open("GET", "b.html", true);
xhttp.send();
}
You could include an HTML code from another file without scripting using SSI (Sever
Side Includes).
Just name your file with .shtml extension and write something like at the place you want to include your file (e.g. index.html):
<!--#include virtual="/galerie/index.html" -->
Usually SSI works in .shtml files by default without any configuration.
Web server will work up .shtml file, looks for SSI directives inside it and process them.
I've succesfull integrated galerie in script. :) Thanks all guys for youre tips. I've used iframe . Finaly worked
