I have a html + css + javascript application.
I want to be able to enable theming.
All my css are replicated in two folders: /theme1/... and /theme2/...
So my html looks like:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="theme1/file1.css"/>
<link rel="stylesheet" href="theme1/file2.css"/>
....
....
</head>
<body>
.....
</body>
</html>
I want to be able to change using javascript the home folder of the css (theme1 to theme2).
Any ideas?
Here is what you will need to solve the problem:
Get the relevant tags. In this case, any link tag with rel="stylesheet" will probably do, but you can even go so far as to specify "starting with theme1" if you want. This can all be done with document.querySelectorAll("link[rel=stylesheet][href^=theme1]")
Loop through them. A simple for loop will do nicely.
getAttribute("href") gets the string you need.
replace() will allow you to replace the part of the string you want.
setAttribute("href",newattr) will put the attribute back into the tag.
<link id="foo" rel="stylesheet" href="theme1/file1.css"/>
When you want to change the theme:
document.getElementById('foo').href = 'theme1/file2.css';

I have two html files named homepage.html & dashboard.html at same level under same folder. I only want to fetch a particular div as my main project has a lot of divs.
Here's the code of homepage.html
<html>
<head>
<meta charset="UTF-8">
<title>Homepage</title>
<link rel="stylesheet" href="css/homepage.css">
</head>
<body>
<div class="homepage-side-menu">
<div id="homepage-home">
<label>Home</label>
</div>
<div id="homepage-dashboard">
<label>Dashboard</label>
</div>
</div>
<div id="homepage-main-view"></div>
<script src="js/homepage.js"></script>
</body>
</html>
And here's the code of dashboard.html
<html>
<head>
<meta charset="UTF-8">
<title>Dashboard</title>
<link rel="stylesheet" href="css/dashboard.css">
</head>
<body>
<div class="dashboard-side-menu"></div>
<div id="dashboard-main-view"></div>
<script src="js/dashboard.js"></script>
</body>
</html>
I want to only fetch the content from the div class="homepage-side-menu"> and show it under <div class="dashboard-side-menu"></div> using simple JavaScript.
First you have to refer the file which you want to consume. then you use getElementByClass()
here is how you import the html file into another html
<link href="homepage.html" rel="import" />
or using javascript:
<script>
$(function(){
$("#addContentFromAnotherHTML").load("homepage.html");
});
</script>
and you can view something like this:
<body>
<div id="addContentFromAnotherHTML"></div>
</body>
something like this:
var classData = document.getElementsByClassName('homepage-side-menu');
Since html5 you can use imports
<link rel="import" href="/path/to/imports/stuff.html">
In older browsers the only way is using javascript (XHR, fetch, or Jquery .load
Using jQuery you could add this to dashboard.html :
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script>
$( ".dashboard-side-menu" ).load( "homepage.html .homepage-side-menu" );
</script>
There are several ways in which you can share HTML template across several pages
1. jQuery - AJAX load() Method
$(selector).load(URL,data,callback);
The load() method loads data from URL and puts the returned data into the selected element.

2. Server side inclueds using some server side programming languages
<?
php include 'header.php';
?>

3. Using some build tools like gulp or grunt or webpack

4. Using HTML imports
HTML imports is an exciting technology that promises to change how we build websites. Imports allow you to include HTML documents within other HTML documents.

This one is recomended but not works with older browser
I'm trying to design a webpage somewhat similar in appearance to Microsoft's. (https://www.microsoft.com)
This includes building a image slideshow, which is why I looked up W3 Schools and found this: https://www.w3schools.com/howto/howto_js_slideshow.asp This is a great example and when writing all of my code in one html document it works, however, as I try to link to an external stylesheet it doesn't work anymore. I could alternatively founder on the js link but I don't think so, as switching to the next picture works. I searched stackoverflow for it already and people suggested adding ?v3 (or sth. like that) to the link, clearing my cache and so on. - so far nothing worked for my. I tried this in Chrome and Firefox.
Here's how I link to my CSS: (it's in the head)
<style>
<link rel="stylesheet" type="text/css" href="new theme.css">
</style>
Here's the js link: (at the end of the body)
<script type="text/javascript" src="js/new script.js?v=3"></script>
Any ideas why this could be? Maybe some other tutorials for this?
I'll include pictures of the working html which's got everything stuffed in it and one of the html with external js and CSS.
Thank you very much!
external - not working
internal - working like a charm
THANKS EVERYONE! - Simple spelling mistake! Sorry to bother you!
This is invalid :
<style>
<link rel="stylesheet" type="text/css" href="new theme.css">
</style>
Between <style> and </style>, there must be CSS code. However link is not CSS code, that's an HTML tag. The correct syntax is just :
<link rel="stylesheet" type="text/css" href="new theme.css">
Then, "new theme.css" has a space in its name, so it will likely be encoded to "new%20theme.css" and you'll get a 404. Don't use spaces within file names.
Finally, open your console to see any errors, especially to check if the CSS file is being fetched successfully.
Don't use any spaces in the names of the files, try using new_theme.css and new_script.js
Reference your CSS like this at the top of your HTML - inbetween the <head> tags.
<link rel="stylesheet" href="new_theme.css">
Also always try either Camel Case - "newTheme.css" or use an underscore "new_theme.css" when naming your files!
That should fix your problem! :)
You should not include the inside the style tag.
It should be inside the tag.
Ex.
<head>
<link rel="stylesheet" type="text/css" href="new%20theme.css">
<head>
Also when you have file names with spaces in between, you need to encode the name.
Example
href="new theme.css"
becomes
href="new%20theme.css"
<link rel="stylesheet" type="text/css" href="newtheme.css">
or
<style type="text/css">
css code here
</style>
open your console to see if it could find your css file
I have the following code, and it is doing what I want but I can't get any styling on it, and I was wondering how to do that? I've tried pointing CSS to the body but it still does nothing. My goal is to control the font size, the positioning, and the font colour. Please ignore the CSS call
<!DOCTYPE html>
<html>
<head>
<title> SUCCESS</title>
<link type="text/css" rel="stylesheet" href="SUCCESS.css" media="screen">
</head>
<body>
<script>
document.querySelector("body").addEventListener("keypress", function printer()
{
document.write('SUCCESS');
})
</script>
</body>
</html>
document.write will accept HTML tags. Try something like this
document.write("<p style=''>Success</p>");
But I suggest you the better way is create an HTML element already with styles and change it according using getElementById or something
So easy, use this javascript, look:
function CustomWrite(a,b) {
b = '"'+b+'"';
a = '<span style='+b+'>'+a+'</span>'
return document.write(a);
}
how to use, look:
CustomWrite('SUCESS','you css code here');
I have an angularJS function, and to make it works, I added some code to the html and body tags: <html lang="en" ng-app="plunker" ng-controller='headController' >, <body ng-controller="MainCtrl"> But after I did it, some css code that I use stopped working, and my background image has gone.
How can I fix it? I don't have much experience with angulatJS, so I will be grateful for an advise.
The code I use should change CSS if I press a button, I'm trying to use this example: http://plnkr.co/edit/jBtP6FfmeRzOYUCnHg3t?p=preview
You just have to replace
<link rel="stylesheet" href="{{stylePath}}">
With
<link rel="stylesheet" ng-href="{{stylePath}}">
Because href is standard html and does not bind with input therefore not registering changes.
Trying to replace the conents of a whole page ( works ) + also replace the link to a style.css to game.css, with query
$.get('/games/14', function(data){ var $page = $(data);
$('head').append('<link rel="stylesheet" href="style2.css" type="text/css" />');
//$('#layout').empty().append($page);
$('body').empty().append($page);
})
I seem to be unable to change the "style.css" to "game.css" no matter what I try, wich Jquery Guru knows how to accomplish this? thx !
UPDATE:
tried the suggestions below still have issues, this is what I'm using now ( no replacement of the .css file )
$.get('/games/14', function(data){
$("link[href='style.css']").attr({href: 'game.css'});
var $page = $(data);
$('body').empty().append($page);
})
Here ya go, just tested this out and it worked.
<!DOCTYPE HTML>
<html>
<head>
<script src="jquery-1.7.2.min.js"></script>
<link href="/assets/frontend.css" media="screen" rel="stylesheet" type="text/css" />
</head>
<body>
<script>
$("link[href='/assets/frontend.css']").attr('href', '/assets/game.css');
</script>
</body>
</html>
To anwer your comment below, I tested it using Firebug.
Using the Console tab, I can see that it first attempted to load up assets/frontend.css, ran the JS, then attempted to load up assets/game.css.
I then checked the DOM in the HTML tab of firebug, and saw that the link elements href attribute was updated.
Target the link element with href attribute 'style.css' and replace the href attribute of that element with 'game.css':
$("link[href='style.css']").attr({href: 'game.css'});
You can use jQuery's attr() function to change the href.
$("link[href=style.css]").attr('href', 'game.css');
There's probably a more rock-solid selector you'll want to use, but that'll do it.
href attribute substitution as suggested in other answers is inconsistently handled by different browsers (i.e. may not trigger re-flow/re-render). Instead, the original style element has to be removed and a new element with the desired href has to be inserted in its place. An intuitive way to do so with jQuery:
$('link[href$="style.css"]').replaceWith('<link href="game.css" ... ></link>');
