How is Github Changing Pages and the URL so smoothly without AJAX?
(2 answers)
Closed 8 years ago.
When I am using the twitter website https://twitter.com/ and click on the tabs on the top there does not appear to be any white page where the page is loading. If I click on a different tab I see a spinner in the middle top of the page then the new page appears instantly without a blank white page in-between.
How is this achieved? I should note I am using Google Chrome web browser.
Small update to this, I noticed white page in between my pages and was comparing it to twitters page load. Then I took out the modernizr javascript library then my page rendered fast just like twitter and I don't notice white page in-between. So I think, this question is really not a good question now as the reason I was seeing white page was the modernizr library.
They are using AJAX, check it out

How to load image (and other assets) in Angular an project?
(10 answers)
Closed 7 months ago.
I have a question about how angular and webapps work in general;
Let's say I load image once on my landing page, and then reuse the image on another page in the same domain using router-outlet. Does this image load once for every page, or can I reuse it later for background purposes without much dalay/any at all, because the image is already loaded?
Your question can actually be answered without considering the specific JS framework you are using: as long as your are using the same path for loading the image the image is actually taken from the browsers cache after it was initially loaded.
Please note that you can disable this behaviour temporarily while developing when you open your development tools (F12) in your browser an tick "Disable cache" in the Network tab:
Often the opposite of your question is the problem - how can I as a developer prevent the browser to cache an image.
I am trying to embed a html file inside my website.
I am trying to embed a chart into the website, but I just can't make it, so that chart is fully displayed. Does anyone know how that works? I could not find anything on the web and i am not that good at programming yet.(after all i started my apprenticeship as a software developer 2 weeks ago.)
Screenshot
As you can see there is 2 scrollbars on the side, 1 for the chart and 1 for the page it's self. There also is a horizontal bar for the chart. I basically just want there to be 1 bar for the page it's self if you know what i mean

What are the new frames? [closed]

Once I have the nav bar designed with HTML and CSS elements... if I put the HTML in its own file, can I link to it some way in the other pages so that the nav bar shows up?
The CSS is in its own file already of course.
The HTML includes a list with the nav bar topics, plus the banner across the top of the page and some images. We want that same banner and nav bar on every page. (It's for a small non-profit group.)
In all the sites explaining how to create a nav bar, I have yet to see mention of this idea. It's like subroutines (except no variables passed).
Thanks. The problem was solved with the Include statement!
If I get you right, you can do the following with PHP:
include("header.html");
Just change header.html to the location your header is saved and insert the code in every page.

What are the new frames? [closed]

When I tried to create a link that would refer to a new website within my page I wondered how this is done right. I used the following code:
<li>Aktuelles</li>
It's a simple link and when clicked, the page appears, but without the navigation bar at top.
My question is: Is there any other way to create a link (For example one frame at the top and one beneath it, and the at the top always shows the navbar) or do you always code the navigation on all subpages in your project?
It's best to store your navigation in one file, for example nav.html and include it in each file you have. In that way it will be present in all your pages and in the same time if you want to edit your navigation you just have to edit in one place and not in any file.

Using HTML5/Canvas/Javascript to take screenshots
Is there a way to copy the main graphics context of the HTML page into a canvas?
From Javascript, I'd like to grab a "screen shot" of the current visible HTML page and copy it to a thumbnail image or canvas. (Not from a separate "screen capture" app, but from within the javascript page itself)
You can't do it.
But If you using google chrome you can write a chrome extension, this give you new javascript functions for capturing images, for example:
chrome.tab.captureVisibleTab( ....)
For example, you can check the source code Webpage Screenshot Extesnion:
