I have a problem on the initial load of my angular APP on mobile safari, it hangs with blank page for nearly 2 minutes, while on other browsers,it works perfect, even on MAC safari and IPAD safari.
At a first guess, maybe my app has too many js files. So I concat
them(11 files) into 3 files, and the issue was resolved. Seems mobile safari has some limitation of the number of js files on the first page. So I tried 4 files, and 5, and it seems 4 is the max number accepted by mobile safari.
My question is: Is there really any limitation for mobile safari on the first page's number of js files? Or did I misuse angularJS or HTML5,or anything else. Because I think if safari really does, it seems awkward, and it should be carefully documented which I never searched on google.
The original code of my first page looks like:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<base href="/"/>
<!-- Bootstrap core CSS -->
<link rel="stylesheet" href="../bower_components/bootstrap/dist/css/bootstrap.min.css">

I created an app in plunker using Angular 4.
Link to the code
I did it at the first moment using Chrome as my browser, but when running anything was happening. After trying various solutions, I decided to open the same plunker on Safari and then worked without an issue.
Could you please tell me why on Chrome is not working my solution?
<html>
<head>
<base href="." />
<script type="text/javascript" charset="utf-8">
window.AngularVersionForThisPlunker = 'latest'

System.import('app')
.catch(console.error.bind(console));

</html>
I found the issue in my Plunker.
After I open in incognito mode and I saw that was working. I decided to check the Chrome plugins, as was thinking that was the issue.
I discovered that was my AddBlocker plugin which was causing the issue.
Now I resolved just whitelisting in the Adblocker the site.
If anyone will have a similar issue a good thought is to check plugins conflicts or issues.
I gave a try to Bootstrap but I'm bit surprised about one thing is that it seems that the Glyphicons are kinda really slow to be loaded or displayed.
I have the feeling that even the carousel is faster to show up.
However, it does not seem that be that slow on other websites.
Therefore, I guess I must have done something wrong, but I do not see a lot of differences with the code used for displaying glyphicons online, is there any way to fix it up?
But so far since I'm trying to run everything locally, it should fast as the light, nope? It takes two seconds for the glyphicons whereas the rest it's instantaneously displayed.
Is there any way to have a better way to measure how fast something can be displayed onto the screen (rather than just using my end-user feeling), please let me know.
Just starting to do web front-end development, please be indulgent.
Here is below the code I am using to display just one glyphicon-home:
<!DOCTYPE html>

I found out what was the wrong, the bottom line resided in the bootstrap.min.css.
Reason is that a while ago I used an online bootstrap customizer cause at that time I havent installed any CSS preprocessor yet. It was enough to change a couple of colors.
However, I did not know that the customizer added a couple of links about where to get certain fonts online which I would rather like to avoid since I'm in China and some websites are really slow to access.
E.g.
#font-face{font-family:'Glyphicons Halflings';
src:url(http://bootstrap-live-customizer.com/bootstrap-3.3.5/fonts/glyphicons-halflings-regular.eot);
I am working to take an existing, medium-complex Angular app and use Ionic to make a mobile version. I am running into a series of issues that I think are related to ui-router, which the app uses. To be specific, in index.html (removed some stuff for clarity):
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="shortcut icon" href="/img/icons/favicon.ico">
<title>My App</title>
<base href="/">
<!-- cordova script (this will be a 404 during development) -->
<script src="cordova.js"></script>
</head>
<body ng-app="myApp">
<div ui-view>
<script type="text/javascript" src="/js/app.js"></script>
</div>
</body>
</html>
Notice the
<base href="/">
and the use of absolute paths for the js and favicons (also using this for the css)
When I use Ionic serve, things are fine. However, if I try to run this on an actual device, Ionic can't find the js, css, or favicons. I can fix this by removing <base href="/">, changing the asset paths to be relative, and setting $locationProvider.html5Mode(false) in the js.
However, this totally breaks links all over the rest of app. I'm not sure why the app is set up this way and the we don't have the ability to fix the app to be more straightforward. I've spent a fair amount of time trying to figure out how to make Ionic work with this odd setup, but have failed. Any advice would be extremely helpful. Thanks in advance!
i am trying to implement the push.js engine from ratchet:
http://maker.github.com/ratchet/#push
i downloaded the ratchet files from here:
http://maker.github.com/ratchet/ratchet.zip
and am using apache to serve all js, css and html. all files are in the same directory.
here is my one.html file:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Ratchet template page</title>
<!-- Sets initial viewport load and disables zooming -->
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
<!-- Include the compiled Ratchet CSS -->
<link rel="stylesheet" href="ratchet.css">
<!-- Include the compiled Ratchet JS -->
<script src="ratchet.js"></script>
</head>
<body>
<!-- Make sure all your bars are the first things in your <body> -->
<header class="bar-title">
<h1 class="title">one.html</h1>
</header>
<!-- Wrap all non-bar HTML in the .content div (this is actually what scrolls) -->
<div class="content">
<ul class="list">
<li>
<a href="two.html">
<strong>two</strong>
<span class="chevron"></span>
</a>
</li>
</ul>
</div>
</body>
</html>
and here is my two.html file:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Ratchet template page</title>
<!-- Sets initial viewport load and disables zooming -->
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no">
<!-- Include the compiled Ratchet CSS -->
<link rel="stylesheet" href="ratchet.css">
<!-- Include the compiled Ratchet JS -->
<script src="ratchet.js"></script>
</head>
<body>
<!-- Make sure all your bars are the first things in your <body> -->
<header class="bar-title">
<h1 class="title">two.html</h1>
</header>
<!-- Wrap all non-bar HTML in the .content div (this is actually what scrolls) -->
<div class="content">
<ul class="list">
<li>
<a href="one.html">
<strong>one</strong>
</a>
</li>
</ul>
</div>
</body>
</html>
how do i link these two files together?
it looks like push.js is included but when i clicking on the a href's does nothing.
i feel like i am missing something glaringly obvious about this implementation.
thanks for the help.
Ratchet works off of touch events, which are not available in your browser. In Chrome go to chrome://flags/ and enable "Force enable touch events". That should do the trick for browser development. If you want to make this work on desktops without the flag you are going to need a js framework to convert touch events to pointer events. Something like https://github.com/maker/ratchet/blob/master/docs/js/fingerblast.js should do the trick.
Ratchet uses touch events on mobile devices that are different than the pointer events used in a desktop browser.
You can use the Chrome flags as mentioned in earlier answers or your can use #fat's fingerblast.js that converts touch events to pointer events.
The fingerblaster.js file can be found here:
https://github.com/stephanebachelier/fingerblast.js
IMPORTANT: In order to enable fingerblaster.js you need to include a script such as the following at the end of your body element (once your html content has loaded):
<script type='text/javascript'>
var fb = new FingerBlast ('body');
</script>
This will create a new FingerBlast object and set the listener on body of the html document (you can put any css selector string in place of 'body').
I asked the same question. Seems like it only works on ios / phones, not on the web browser.
See: https://github.com/maker/ratchet/issues/148
I found that Ripple Emulator works great with this "issue" (I think only is available on Chrome)
It's nice because you don't need to add another js library
Modern Firefox browsers have a web developer feature called "Responsive Design View". It allows you to view a web page in a smaller viewport to simulate use on a phone/tablet. It also allows you to simulate touch events. I found it particularly useful when working with Ratchet on a web app.
In Firefox, you can enable the Responsive Design View by going to Tools -> Web Developer -> Responsive Design View or using the hotkeys "option + command + m".
More information on the Responsive Design View can be found here.
You can download Chrome Canary and with Developer Tools click over Phone icon ( first one ) then select which mobile phone you want to emulate, you can even use Responsinator.com.
PushJS is embedded into ratchet.js.
Use FingerBlast. Tried Chrome, Safari and it worked.
https://github.com/stephanebachelier/fingerblast.js/blob/master/lib/fingerblast.js
On Google Chrome you can use the developer console and emulate a mobile device with touch events
https://developer.chrome.com/devtools/docs/device-mode#emulate-touch-events
I'm writing a mobile web app with jQueryMobile and I put in AngularJS to handle data binding. But this introduces routing problems on mobile devices. Below is the minimal code I could write to reproduce the problem. Everything works OK on Chrome on desktop, but when I try the same page from my android device I get the nasty "Error loading page". Problem can be fixed by using data-url for navigation but there's catch. I also need to package it up with phone gap. This means html is loaded by file:// and direct navigation(data-url) doesn't work(I tried)
<!DOCTYPE html>
<html ng-app>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.min.js"></script>
<script src="https://raw.github.com/tigbro/jquery-mobile-angular-adapter/master/compiled/jquery-mobile-angular-adapter-1.2.0.js"></script>
</head>
<body>
<div data-role="page" id="main">
<a data-role="button" href="#sub">sub</a>
</div>
<div data-role="page" id="sub">
<p>sub page</p>
</div>
</body>
</html>
Upon clicking the "sub" button user should be directed to hostname/#sub and it is on Chrome but weird things happen on android and browser is routed to hostname/#!/%23sub
I guess this is URL encoded?
Also I should point out that by removing just the two script refenrences for angular and for JQM-angular adapter everything works(and no databinding of course).
i tried removing angular-jquery adapter and everything works as if by magic.
also no issues with angular and jquery clashing.
