Get Rid of Spinning "Loading" Appearance on iOS Safari with SignalR - signalr

Is there any way to disable the spinning "loading" appearance of a web page that's using SignalR from a web page on Safari for iOS? I understand that it's probably using long polling, but it makes it look like the page has never finished loading.

This is a known issue, there's no straight-forward work for all browser fix which is why it hasn't been fixed yet.

Mobile Safari, Css animations freeze on navigation

So I'm working on a mobile website for a client and have added a css loading animation that triggers when users navigate pages or on ajax load.
The animations work fine in Chrome, but in IOS I've found that immediately after triggering navigation (via window.location.href or just clicking an anchor tag), the loading animation just freezes. This happens at the beginning of the call, not after the page is loaded, so there is a decent amount of time where the css isn't doing anything and the site looks like its hung up on something. I'd also add that the animation works when I'm just doing ajax calls.
In the meantime I've set up a delay between when the animation loads and when the navigation actually happens, and it helps somewhat with the look and feel of the site, but its not great.
Any solutions or ideas around why this might be happening?
Animations freezing after navigation is triggered seems to be a general issue with Webkit browsers.
See https://bugs.webkit.org/show_bug.cgi?id=16177
There is a workaround if you can send the request via Ajax/XHR. Then the animation will keep playing. You can trigger the navigation after receiving a 200/ok response from the backend service.
Should you load the entire next page and swap content by Javascript, you may want to pay attention to the browser history API, i.e. add an entry to it for the swapped page.
Apparently there is a workaround if that suits your case: using transform instead of all other properties. See https://stackoverflow.com/a/53178319/647845

Flicker on Postback in Chrome Browser

In this web application,there is a huge flicker on postback when accessed in Chrome browser. However, it does not happen in IE and Firefox.
What can be the possible cause?
Here is the video that shows flicker in Chrome and here is the video that shows smooth navigation in Firefox.
Any help will be highly appreciated.
ps: this web application uses Telerik controls.
Thanks
Just try this
switch off 'Hardware acceleration' from the Advanced Settings > System
options
This might solve your issue. This issue was raised as a bug in Chromium project earlier.
Also try to see the console if any errors are coming up.
I know that this is not a specific answer but hope this helps you.

How do I make a mobile-friendly popup on my website?

Is there a simple way to trigger a mobile OS's native pop-up/alert/etc. from some form of web code? I'm writing an ASP.NET mobile web page and I'd like to, for example, have the iPhone's UIAlertView appear.
EDIT: What I'm looking for is not the method with which to detect which mobile browser is accessing the site (I already know how to do that). If the code to trigger a pop-up that will look nice in an Android browser is different than the code to trigger a pop-up that will look nice in an iPhone browser, I can simply throw in a switch statement that redirects the user to the pop-up that corresponds with their browser. I'm trying to find the html/javascript/asp.net code which will create a mobile-friendly pop-up, either in general or for the various popular mobile web browsers specifically.
Don't know whether there is any pre-built functionality in .NET that can achieve this, but you can surely write one yourself.
You can write a method, that returns the code for your popup, based on the user OS (simple switch statement should do).
EDIT after taking a short nap:
I believe you should reconsider using popups. They are quite annoying even on desktop browsers and many people block them automatically. Probably every blog about accessibility will tell you, that you should keep mobile version of your website as simple as possible because of various compatibility issues that you can run into.
Instead, try to think about some interesting way to incorporate messages for users in a different and appealing way, that won't disturb anybody.
What I do is use a div popup (that floats ontop of the page) and eighter make a big close button or set at timeout to remove it.
jquery mobile is a good place to start.

close current web form in asp.net

How i can close current web form in web based application?
I have tried with following code:
mybutton.Attributes.Add("onclick","window.close()")
But its not working
Help me. Thank you.
You can use window.close() to close a pop-up window only. If you really need to close the window, use a pop-up instead. However review why the closing is important? You may consider a redirection (either server.transfer or response.redirect).
Update:
Looking at the discussion at this stage, we need to see the relevance of why wee need to close the window as desired. What is the business value that we are achieving?
You can use the following script to close the current window in Chrome and IE (I checked in IE8).
mybutton.Attributes.Add("onclick", "window.open('', '_self');window.close();");
but it still won't work in Firefox. See more info on this: How can I close a window with Javascript on Mozilla Firefox 3?
But because it is a workaround (as Kangkan said window.close() should be used only to close popup window created by window.open() ), it is not a reliable solution and can be broken if a new browser version is out.
Bottom line: there is no reliable, universal solution for your problem, there is no proper way to close a non-popup window from javascript. If you can rely on the fact that your site will be used only in IE, Chrome, etc. you can use a workaround/hack (see above - but don't forget, it can easily be broken in next browser release), otherwise you should consider a different approach of the problem, instead of closing the window.

Why does the following flash not initially load in firefox, but works in chrome and IE

The following flash does not initially load in firefox, but if I click the second tab on the right, and then go back to the first, it loads. This works in Chrome and IE. Here is the webpage.
This is odd, normally things dont work in IE but do in Chrome and Firefox. Upgrade your Flash Player is my advice
Have you ruled out the possibility of it being a browser problem and not related to the site?
Does Firefox do this for any other sites?
Try clearing you cache and upgrading your Flash plugin to rule out the browser.
At a guess, a timing issue. Flash doesn't keep a network stack, it merely passes network calls to the browser, so any kind of logic that is sensitive to the timing or order of loads, load events, etc., can function differently from browser to browser.
But it's impossible to say more without seeing some code.
