I am surprised by the display system of Youtube. When we are on the main page https://www.youtube.com/ and we click on one link of the menu at the left side to go to this page for example https://www.youtube.com/feed/trending, there is no flashing when going from one page to another.
It looks like the new page is preloaded and then display only the difference with the page before.
Furthermore there is the progress bar system (like this one http://ricostacruz.com/nprogress/) which ends all the time at 60% on the current page, then starts at 60% on the new page and go straight to 100%.
Any clue how they do that? Javascript, specific server configuration?
Thanks
This is a feature of frameworks like Angular or React, as a single page app (SPA), which use data APIs to load data and two-way binding to dynamically update only the things that have changed.

So for example, instead of facebook.com loading up like this below:
I would like the webpage to load up with a callout to a specific section with the background darkened:
And to have a step-by-step callout sequence going on to the next callout:
What's the correct term for this kind of setup and do you have any good tutorials to share for this?
please understand that I'm a total noob in coding.I'm working on a page of my local Scouting community that allows the visitor to type a number (which represents the age of their child. Ages from 0 to 18), which has to put something in motion so that the troop their child belongs to, instantly shows up on the page (without refreshing the page).This is my idea: https://i.stack.imgur.com/IzAM6.jpg(Text from the image:)
On the left side from top to bottom:- Visitor can click on boy/girl- Results shows directly after input. No Refreshing- Content loads after an upwards motionOn the right side from top to bottom:- Result remains on page until reload/backspace

So I have been looking into this for a few weeks and have come up with nothing!
I work on the website for my families music store, and have been asked to add a "Links" page to the website. My goal would be to have the categories of our vendors (i.e. Violin, Guitar, Piano, etc.) on the left of the page and when the category is selected the links come up on the right. That part I have. The tricky part here is: When a link to a vendor (i.e. Fender, G&L, Yahmaha) is clicked instead of taking them directly to the site, I want it to take them all to the same page, but embeded on that page is the site.
I have done a lot of research on this and have come up with nothing. I could just go through and make a new page for each of the vendors, with the embedding on each individual page, but that is extremely time consuming with the amount of vendors.
Is something like this at all possible? I've been playing with embedding itself and have that down. It just comes down to, which link did they click, and loading that specific page.
If there is any more information you may need to help or point me in the right direction please let me know! Same with any code that may be helpful!
I've come up dead on all my research on this.
EDIT: I guess my ultimate goal is that it will look something like this: http://answers.yahoo.com/ so that the vendors website is open on bottom, but our stores banner and links are still at the top. Out website can be found here: http://www.brassbellmusic.com/default.aspx
I've created a JSFiddle to demo this functionality using jQuery.
We iterate through the list of brand links in the ul:
$('#brandListing a')
Capturing a click event on each:
.click(function(ev){
jQuery passes an event object to the anonymous function (ev). When the link is clicked, we first must prevent the default action, which is to follow the link. Then we update the src attribute of the iframe (the "embedded page") with the value of the href that was clicked:
ev.preventDefault();
$('#embeddedBrandWebsite').attr('src', ev.target.href);
You'll need to add the jQuery library to your page to use my code sample, but it's possible to replicate the functionality without it.
EDIT
The sample above is for a single page implementation, where links and the embed are on the same page. To achieve the requested "transfer of information," I recommend passing the target href as a GET parameter (brassbellmusic.com/brandEmbed.aspx?path=http%3A//www.gibson.com/). On the single "embed" page, you can then extract this either on the server side to set the iframe's src, or using javascript. With javascript, you might use:
function getURLParameter(name) {
return decodeURI(
(RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
);
}
Source
And then after your document is ready, set the iframe src using getURLParameter('path').
im nearly ready to launch my website but i have a problem i cannot sort out.
ive built the whole website using wordpress and buddypress.
due to the picture in my header being very big and ending 450px down the page, you have to scroll down to access the buddypress menu in the relevant page (the one above the activity stream etc) which is exactly where i want it, removing my header is not an option, now the only problem i am having is that when i click the tabs in the buddypress menu say from activity stream to say my messages instead of the page laoding and taking me back to this section it takes me to the very top of my header so i have to re-scroll back down to the page i was after.
I need the page to stay at the same point after page reload so that the menus can be flicked through without having to scroll down to it again everytime a link is pressed. how do i achieve this? can you please help me sort this out….i have no problems adding or editing codes if i know what code needs changing and what to add to make it do this. thx
Im guessing that if you look in the url bar it is adding a # to the end of the url. You need to override the default click event on the a tag so that it doesnt jump you to the top. Im not sure how that will affect the stuff that is going on in the BuddyPress plugin.
I'm working on my website where I have a music player. The annoying part is that when I browse to another page the player stops and starts from begining...
What I want is to have a persistent music player. So how can I make the div that contains the music player to be static when browsing to another page?
The website: demo(dot)zdringhi-art(dot)com
Thanks!
WEB is stateless.
So if you move to another page there is no way for a div to remain the same.
Although what you can do is that... Hmm as follows.
Have a single page and have your div in there.
Then the other part of the page is loaded via ajax.
also when a link is clicked only parts of pages will be loaded.
Seems too much of coding , but is the only feasible option.
For eg take facebook
Gurav shah is correct, the web is stateless so if you are changing pages you only have a few options for this.
Frames, yes before anyone shouts this is what they were designed for. You could have the music player in one HTML frame and the rest of the page in another so when you move around you are only updating the main content frame.
Or do as gurav suggests and make your whole site one page and update the content with Ajax, so the music Div does not change.
Pass the current position of the player to the next page when you click a link.
to another page
Where getseconds() returns the current position of the music player and passes it to the next page then when that page is loaded you read in the variable from the URL and start the player from there.
Using frames is one solution but since you are using JQuery on your site you should check out .load (http://api.jquery.com/load/). It allows you to load the content of another page and put it somewhere in the current page. Something like this:
$(function () {
$("a").click(function (e) {
e.preventDefault(); // don't follow the link
$("#ja-container").load($(this).attr("href") + " #ja-container");
/* Load the new page using ajax request, take the content in #ja-container from that new page and put it in the current page's #ja-container */
});
});
This is not a complete solution: when someone clicks Concerts -> Agenda you should keep Agenda visible.
Personally, instead of forced background music I'd rather like to see a page with Youtube videos of the people playing the music.
Well, yes HTTP is stateless. what you can do is create a cookie, and update it with current location/time value of the player, constantly. This way, when you go to any other page you can read time/location from cookie.
otherwise, in a cookie less approach, sending AJAXed location/time data back-forth server-client will be too much network.
If I was doing this, I would have gone cookie way.
