I have many different directories which are named SOMECITY-STATE.
Each of these directories has one and the same index.html, with only one difference, the header image is different in every one of them.
Now I have a separate header-image folder in which the images are named all the same like SOMECITY-STATE.JPG
What I want to do is, to put some code in html file to make it automatically read the directory name e.g. NEW-YORK-NY and make the page display the ../banners/new-york-ny.jpg as it's header image.
<div class="header-image"> <img src="banners/new-york-ny.jpg"> </div>
Where mydomain.com/directory1 should display the image ../banners/directory1.jpg and mydomain.com/directory2 should display the image ../banners/directory2.jpg
Is this possible?
It is indeed.
Just before the ending </body> tag inside each index.html file, include this code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
var loc = window.location.pathname;
var dir = loc.substring(0, loc.lastIndexOf('/'));
$('.header-image img').attr('src', '../banners/' + dir + '.jpg');
</script>
What's happening?
The first line adds the jQuery library to your webpage, which makes what you're trying to do much easier.
Next, I put some code inside <script> tags, so the browser knows it's going to be Javascript.
The first line inside the <script> grabs the folder that your index.html file is in, but it looks like "/new-york-ny/" right now.
The next line takes "/new-york-ny/" and takes off the last slash, so it's just "/new-york-ny".
The last line of code selects the image within the div with the header-image class, and sets its src attribute to "/new-york-ny", but also adds "../banners" and ".jpg" to it at the same time, making it "../banners/new-york-ny.jpg", which is hopefully what you want.

I hope it helps!

I worked on a little startpage for my browser. Now I would like to make some changes to it, so it updates the index.html file depending on a text file, when this got changed. What whould be an efficiant way to solve this problem?
My approach would be to create a text file and read line by line from it and update the html file. In the text file I would store the links shown on my startpage - I thought maybe something like this:
|cat_media
https://mailbox.org,mail
https://netflix.com,netflix
...
http://crunchyroll.com,crunchy
https://jott-uh-be.bandcamp.com,bc
|cat_social
https://pr0gramm.com,pr0
https://stackoverflow.com,stackoverflow
https://twitter.com,twitter
https://instagram.com,insta
When the line starts with the symbol |, it creates a new <div> with the class category and the string in that line (e.G. class= 'category cat_media'). Otherwise, if the line starts with http, it will add a href-link (e.G. <a href='https://mailbox.org'>mail</a>) to the html-code.
I got this website hosted on my raspberry pi with nginx and uploaded it to my github pages.
You don't have to update the index.html file.
You can create dynamic content.
You can use PHP:
You can learn it here:
https://www.w3schools.com/php/default.asp
And here is how to read a file
http://php.net/manual/en/function.fread.php
Or if you cant use PHP you can use Javascript:
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script>
$(() => {
$.ajax({
url:'your-config-file.xt',
success: function (data){
console.log(data); //this is the config file. just for loop it and modify the dom
}
});
});
</script>
But your config file must contains the string how the links should be shown.
For example:
|catergory one
yt: https://www.youtube.com
I am a technical writer and in the process of importing our content (HTM) into a new platform (Still HTM format). During this process I also want to use Prettyphoto to give users the ability to click on screenshots to vew a bigger version.
I have this now in my html code:
<a rel="prettyPhoto" href="images/xxxxxxx"><img src="images/23456.png" class="screenshot" alt="some alt text" />
There are thousands of files and each file could have many such images in them. where the name of the image changes but the href="images/xxxxxxx is the same
I need the xxxxxxx for each instance to be replaced by the png filename 23456.png or whatever that may be.
Is there an easy way to do this and how?
Thanking all in advance
You could use jQuery for that. The function loops all items with the class screenshot. Read the src property and puts that in the parent href.
<script type="text/javascript">
$(document).ready(function () {
$('.screenshot').each(function () {
$(this).parent().prop('href', $(this).prop('src'));
});
});
</script>
However this is no SEO friendly. If you want the href to be available in the source you are gonna need a server side solution with some programming.
I want to remove 2 lines of my HTML code and put them in another html file (ex: index2.html), but those 2 lines must be before </body> ends.
How can I put those 2 lines in another html file and keep it working as they was never removed?
The code that I want to move is a popup window.
The code that I move is the line that connects with another site and gives me the popup.
<script type="text/javascript" src="https://thesite.com/script.php?id=21940"></script>
And the line that I want to remain in original index.html calls that popup from a button:
onclick="call_window();"
i know that you can have style-sheets in the head of a page, but i like to have them in a separate file. Now i'm working with a single page application.
Well in an SPA the content is dynamic, right? so i didn't want to import all the style-sheets in the head section with the link tag. Can i somehow import style-sheets as-and-when i need them?
I mean, can i have a link in the body, such that whenever my SPA loads some dynamic content, a style sheet also gets loaded? Such that i dont have to load all the stylesheets even when the dynamic content is not loaded..
I stress again: Whenever the content loads, the styles load.
I know i can do it with the help of an inline style like this:
~PSEUDO CODE
<tagname style="somestyle"></tagname>
but can i have some dynamic file imports too? Can i have the link tag in the body too? Even if it works, is it standard?
You should look into asychronously loading assets, such as the famous google-analytics code. You can load external stylesheets using Javascript.
JavaScript
(function(){
var styles = document.createElement('link');
styles.rel = 'stylesheet';
styles.type = 'text/css';
styles.media = 'screen';
styles.href = 'path/to/css/file';
document.getElementsByTagName('head')[0].appendChild(styles);
})();
Lines 1 and 7 create a new scope for variables such that local variables do not collide or override with globally scoped variables. It isn't necessary just a best practice. This solution also assumes you have a <head> tag in your html.
You can add/remove/edit link tags in your head area with java script to add/remove stylesheet files.
Code example:
Add a stylesheet to the head:
var newstyle = document.createElement("link"); // Create a new link Tag
// Set some attributes:
newstyle.setAttribute("rel", "stylesheet");
newstyle.setAttribute("type", "text/css");
newstyle.setAttribute("href", "filename.css"); // Your .css File
document.getElementsByTagName("head")[0].appendChild(newstyle);
To remove or edit a stylesheet you can give every stylesheet an id attribute and access it with this:
document.getElementById('styleid')
Or you can loop through all link tags in the head area and find the correct one but I suggest the solution with the ID ;)
Now you can change the href attribute:
document.getElementById('styleid').setAttribute("href", "newfilename.css");
Or you can remove the complete tag:
var styletorem = document.getElementById('styleid');
styletorem.parentNode.removeChild(styletorem)
I just tried to give dynamic styling to my webpage. I used a button. On click of it, the CSS will get imported using a method in Javascript.
In my html, I have:
<button type="button" onclick="changeStyle()"> CLICK TO SEE THE MAGIC!! </button>
Then in Javascript, I have a method named changeStyle():
function changeStyle()
{
var styles = document.createElement('link');
styles.type="text/css";
styles.rel="stylesheet";
styles.href="./css/style.css";
document.head.appendChild(styles);
}
It worked perfectly.
I'm writing an application, a reporter with heirarchy of folders and files, in the lower heirarchy level there are 2 types of reports: the simple one is a flat (non link) report that being presented as a single simple line.
the second type is a link with a general description in the header and if you press the link you get a full report.
example: if I run a telnet command, I will see the command in the header and if I want to see the entire session with the device I will press the link and it will be presented.
My problem is that most of this lined-files are small but the OS reserve a minimum space for every file so I loss alot of disk space for nothing.
The solution I want to implement is a "dummy" links, which will be presented and will behave like a regular links but actually will be stored in the same file like their "parent" (probably with alot of other links like them).
The solutions I saw so far are only for "jumping" inside a page but this is not what I'm looking for, I want it to be presented like a seperated file and I dont want the "parent" file to present this information at all (the only way to see it will be by pressing the link and even then it will present only this information and not the other file content).
any idea guys?
To link to a specific part in a web page, place an anchor link where you want the user to go to when they click a link with:
<a name="anchor"></a>
and link to it with:
Click here
You can replace "anchor" with a more descriptive name if needed.
To hide/show a div (the following code is untested, but should work)
JQuery solution (If you're using JQuery):
function toggle(divname) {
$(divname).toggle();
}
The corresponding HTML:
<div id="content">some content</div>
<a onclick="toggle('content')">Click here to show/hide the content div!</a>
Non-JQuery Solution:
function toggle(divname) {
var adiv = document.getElementById(divname);
if (adiv.style.display === 'block' || adiv.style.display === '') {
adiv.style.display = 'none';
} else {
adiv.style.display = 'block'
}
}
The HTML:
<div style="display:hidden" id="content">Content</div>
<a onclick="toggle('content')">Click here to show/hide the content div!</a>
