My website is built using angularjs. There are few functions needs to be performed in the front end. This does not make any problem in desktop. But in mobile the page response is slow, (i.e.) say when I click on the 'about us' page the device is waiting for the response but as a user I don't know what's going on. After say 3-5 seconds the page loads.
So I thought of using the nganimate during the page enter and leave. Still only when the page changes the animation works. Is there a way to fade out the page as soon as the user click a link and then fade in the new page? Like is there a way to animate from the '$routeChangeSuccess' for page leaving and enter or any other better way??

Question: With Javascript, can you tell the web browser to begin loading a page, but don't begin rendering it yet?
Issue: A client wants his web page to show listings like a book. When you click on the next button, he doesn't want the next page to immediately load. He wants the book to close (a closing animation) and then load the next page.
Current status: All links go to Javascript. I show the closing animation. Then, I replace the window location. The issue is that there is a clear wait for the next page to load. It would be nice if I could load the following page into cache while the closing animation runs. In other words, I want to make that three-second animation useful time by loading all the HTML, CSS, Javascript, and images for the following page and then all that happens when I set the new location is that it renders.
Possible solution: I have the main page that had two full-screen iframes in it. One iframe is the current page. The other is hidden and is used to load the next page. After the animation, I flip which iframs is visible and which isn't. This is good except that the back button doesn't work properly. If you click back, you go to wherever you were before you went to the website. You don't hide the current iframe and show the one you just hid. If you click back twice, flipping iframes doesn't work. I have to keep a log of your history. Further, I have to hack the back button, which I don't like. So, I'd like to use a built-in cache method if I can.

Yes, this sounds like a good approach.

I have to hack the back button, which I don't like.
Single Page Applications (SPAs) can't use the back button as originally intended because the entire application exists within a single document.
Partly in response to this, we have
history.pushState()
which is a really good extension to the History API, enabling new "artificial" entries (describing new states) to be added to the browser's history, which, in turn, enables the back button to work exactly as the user might expect it to.

"Lazy Loading" might be able to do what you need, although not exactly what you would like to do with a button and javascript. It is an optimization technique that only loads a picture when it's visible on the area of the browser, and delay loading the rest of the pictures until you scroll down or when they should become visible.
You can configure that when a page loads, only the pictures that are "Above the Fold" (printed on the top half of a browser without scrolling down) should load, and delay loading the rest until a user scrolls down to reveal them.

I have a bit of a head scratcher here. My project has a main page in which some transitions happen and some buttons appear. Clicking those buttons allow you to navigate the site. So far so good. On those lets say "secondary" pages I have a series of "back" buttons that take you back to the main page with the following link:
<p class="backContact">BACK</p>
Now, this is where it gets specific. When I return on to the main page, I want to return to the main page that's "cached" so basically the main page AFTER the said animations and buttons appear, not back to the page as if I just had come on the website for the first time. Same for when you hit the back arrow on the browser itself.
The code I just posted with the link was doing just that and it works fine in safari and firefox. BUT in chrome the behaviour is different and when the back button is clicked it goes back to the main page before all the animations happen which is really annoying as I just want them to play the first time round else they become tiresome.
Is there anyway to force chrome to come back to the "cached" previous page? Many thanks
I have a css animation that essentially slides two images with a high z-index off the screen revealing the website content below it on the home page. It is only on the home page and not on any other pages.
What I would like to do is have this animation run only the first time the page is accessed during a session. So if the user navigates to another page and then comes back to the home page, I don’t want the animation to run again.
The only solution I can think of is to create an HTML5 session storage object on the first page load that is checked every time the home page is loaded and use jquery to hide div that contains animation if the value of the object is set.
This seems a bit overkill for such a simple task. Any suggestions on a simpler way of just removing the div that is persistent across page reloads during the session? You don’t have to write the code for me, just point me in a simpler direction if possible. Like is there a way to do this with just CSS. Or if I remove the element using JavaScript will it remain removed after navigating to another page within site and then coming back to home page. Please and thanks!
P.S. This is a custom WordPress theme so I’m open to a PHP solution as well.
You can check the referrer URL and run the animation only if the referrer is not the site itself. But this time the animation won't be shown if the visitor first opens another page and then navigates to the homepage.
Another option would be using cookies.
I'm developing a multi-browser extension using the Crossrider framework.
Is there a solution to show an html horizontal menu on the top of each page ?
The menu will embed a JS script which uses some external libraries.
Indeed, I can prepend my html content to the "body" tag but each time the user clicks on a link on the webpage, the whole page is reloaded which makes the horizontal bar disapear and then reappear on the next page when the loading is completed.
I thought of putting the website content into an iframe but some websites (ex: amazon) send a header with the "X-Frame-Options" set to "DENY" or "SAMEORIGIN". This is something which Crossrider cannot modify (at least I didn't find how to do that).
Is there an other way to show a PERMANENT menu on top of each page ?
EDIT :
My toolbar won't contain any link but it will record the mouse position. My problem is that each time the user will click on a website link (ex : to see a product on the amazon website), the toolbar will be reloaded and so the mouse position won't be recorded until the next page has finished its loading.
Page reload is normal behavior when clicking on a link on Amazon sites and hence the toolbar redrawing when the page loads is normal and correct.
Based on the information provided and assuming I have understood what you are trying to acheive, it appears that you are going about this the wrong way. I would first think about why do you need a toolbar at all? For example, if you are only recording the mouse position when a link in the page is clicked, I think it makes more sense to register to mouse click events of the links you are interested in.
I suggest you rethink your approach and take in to consideration the issues you have to handle, such as the page reload and handling the click event before the page reloads.
