need some best advise on how to achieve load/busy status. In my PWA in index.html I have
<body>
<paper-toast id="toast" text="Hi, welcome!"></paper-toast>
<paper-spinner id="working" class="mainSpinner" active></paper-spinner>
<my-app></my-app>
<noscript>
Please enable JavaScript to view this website.

my-app element has typical app layout as per Polymer Starter Kit. app-toolbar, app-drawer etc. I programmatically turn the active flag of spinner at start of loading and turn it off at end of loading any element or data.
The issue I am facing is the spinner is hidden behind the app-toolbar. If I change the spinner active flag to true it is not shown.
Any idea how I can get the spinner on top of all the elements in the app-toolbar?
I tried putting CSS of the spinner with z-index: -1 but no help. The app-toolbar gets the whole view and in dev tools I can see the spinner is active but tucked behind the app-toolbar hence not visible.

I've created a simple blazor app that has a slider on top. There is a javascript self executing function that adds some inline css to this slider so it makes its' height the same as window.height.
I'm adding this javascript file in _Host.cshtml, before closing the body tag.
My issue is that this inline styling isn't applied. I've debugged the javascript code and it gets the correct height, the element on which I want to add the styling is found, the element.css('height', myHeight) is being called with the correct value, but in the end there is no style attribute on that element. I've also tried, after the component has been rendered, to remove the script tag from the page and add it again, hoping that it will re-run and then change the height, but no success there as well.
I've created a .NET Core WebApp using that same slider and everything works as expected (I have the style attribute on my element). In this second app I add the script before closing the body tag, in _Layout.cshtml.
Seems preety much the same as the blazor app, but for some reason, on that one doesn't work.
Do you guys have any idea why?
EDIT:
I've found something interesting. In the beginning, the page is loaded correctly, but the component is being reloaded after the app connects to the we socket Information: WebSocket connected to wss://localhost:44361/_blazor?id=cepYgPnJYddq2bHSywwwYw.. This is when I lose the inline styles.
So how can I stop it from reloading? I guess this is the question.
I'm using angular 2 in my web application.
My application uses a lot of bootstrap modals.
I noticed that the modals contained inside a sub-route component are not showed correctly.
Infact, the modals contained inside the navbar element (the navbar is in the main state and always visible) are shown correctly, but those that are contained in the sub-route (so the html is loaded dinamically) present a bug... the shadow seems to be above the dialog itself, so it is impossible to press the buttons.
This is a screenshot:
As you can see the backdrop is above the dialog. This happen only on mobile devices.
What am I doing wrong?
I would avoid to keep all the modals inside the navbar and then open them with global events...
Thanks a lot
EDIT: I found this document:
If the modal container or its parent element has a fixed or relative
position, the modal will not show properly. Always make sure that the
modal container and its parent elements don’t have any special
positioning applied. The best practice is to place a modal’s HTML just
before the closing </body> tag, or even better in a top-level position
in the document just after the opening <body> tag. This is the best
way to avoid other components affecting the modal’s appearance and
functionality.
But is this the html of my modals (a lot of modals) is always in the dom. Isn't a heavy solution?
I fixed the problem using the following javascript code:
$('#myModal').appendTo("body").modal('show');
Thanks to Adam Albright for his post.
Hello guys I have two small questions about my facebook application link and JS SDK. So let me explain:
1- Well as I understood from Facebook JS SDK, the should be left just empty. But still I am a little dizzy and I want to make sure whether we should put our page content into it or it should be left empty?
Please make me sure about it.
2- I have put some changes in my css and markup of my page but after one day I can not see some of the changes in my facebook application link.
How can I see the result of changes if there is such a way??
Thank you very much indeed.
Let me answer this for you:
1) Yes, It should be left empty and here's the info on why it's required quoted from JS SDK docs:
The JavaScript SDK requires the fb-root element in order to load properly and a call to
FB.init to initialize the SDK with your app ID correctly.
The fb-root element must not be hidden using display: none or
visibility: hidden, or some parts of the SDK will not work properly in
Internet Explorer.
The SDK inserts elements into fb-root which expect to be positioned
relative to the body or relative to an element close to the top of the
page. It is best if the fb-root element is not inside of an element
with position: absolute or position: relative. If you must place the
fb-root element inside of a positioned element, then you should also
give it a position close to the top of the body or some parts of the
SDK may not work properly.
2) It's most probably a cache problem, there's a similar question with an issue of css which has been answered previously: Caching for css content for iphone FB APP
Also to get your browser/visitors browser to re-fetch your CSS file, The trick is to pass a query param/variable at the end of the CSS file url like so: ?v=1
<link rel="stylesheet" href="css/style.css?v=1">
This will automatically make your browser or maybe even facebook to fetch your CSS file again with the new changes. Make sure to change the number everytime you update your files so you could see the changes instantly.
I'm developing a website using jQuery UI, and there are several elements on my site that appear to be incompatible when viewed on touchscreen devices; they don't cause any errors, but the behavior is not what it should be.
The elements in question are sliders and rangesliders as defined by jQuery UI; on the touch screen, instead of registering a touch as picking up a handle and a drag as dragging the handle across the slider, it just slides the whole webpage to the side of the screen. It does work if you tap the handle and then tap the location on the slider where you want the handle to end up, but this is very slow and not ideal. Any ideas?
I tried downloading the jqtouch plugin and then attaching .touch([...]) to all calls to slider() and rangeslider(), but that didn't work.
UPDATE: I found this "patch" on the jQuery UI website
http://bugs.jqueryui.com/ticket/4143
that says it facilitates slider on iPhone, but now for another question: how do I incorporate this "patch" into my code? Do I just include it at the beginning of the code like a plugin?
This library seems to offer what you're looking for:
https://github.com/furf/jquery-ui-touch-punch#readme
It also has some example use code (simply add the plugin):
<script src="http://code.jquery.com/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script>
<script src="jquery.ui.touch-punch.min.js"></script>
<script>
$('#widget').draggable();
</script>
Just wanted to add some new info about this. Touch-punch will work fine for Ipads and Android devices. But the slider will not work on Windows mobile devices, as far is I could test(with the latest versions of jquery ui & Touch punch)
The fix is quite simple, just add the following CSS-rules to the .ui-slider-handle:
-ms-touch-action: none;
touch-action: none;
Hope this helps
As #dazbradbury suggested, the touchpunch library can help translate the mouse events to touch events. The parameters in .draggable() limit the movement of the slider so it can't be moved beyond its slider parent.
<script src="http://code.jquery.com/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script>
<script src="jquery.ui.touch-punch.min.js"></script>
<script>
$(".ui-slider-handle").draggable({
axis: "x",
containment: "parent"
});
</script>
EDIT: If you are already using a Jquery UI slider, you only need to include the touchpunch library. Do not call .draggable() for the .ui-slider-handle because it will overwrite the existing functionality.
I had the same problem. I developed an elaborate slider UI building on jQuery UI's slider only to realize it doesn't work at all on mobile. I tried the suggestions listed here but since I have a custom solution that's only based on jQuery UI Slider, it did not work.
Just use noUiSlider.
It does all the elaborate features (and much more) as the one I built on top of jQuery UI slider. It works beautifully on mobile devices and is easy to style too.
I'm looking for a JavaScript/jQuery plugin which allows to use a fixed header on mobile browser.
iScroll seems to be the most popular solution but I was interested in a plugin that isn't constantly calculating the position of the header while scrolling.
The idea is the same used by jQueryMobile fixed toolbars, while the user is scrolling the header disappears and only reappears after finishing scrolling.
It's more simple than what you think.
I use this code:
<div data-role="header" data-position="fixed">
<h1>Fixed Header!</h1>
</div>
