This is my first question on SO so i'll try and make it as clear and as understandable as possible.
I've recently started messing around with Angular JS and currently I am working on a mobile app using Angular JS and jQuery Mobile. So far I've not had any major problems and so far have no had a need to consider any external libraries for integration (such as the angular js + jquery mobile adapter). I've created a multi-page app (currently only two pages) and used separate controllers for each page (login + content page). The app itself is simple, it's just a list keeping app and i've created a quick jsfiddle based on the ui aspect of the content page: http://jsfiddle.net/G7JNV/4/
The app works as expected from the jsfiddle. However because the content page is a page in the same html document (index.html) as the login page, to navigate to the content page the url becomes:
.../index.html#mainpage
(mainpage being the page for the list keeper)
Thats when things start getting funny. When the url is like above, when adding an item to the list, the item is initially unstyled (it doesn't look like it's part of the list) but the css styling for that item comes back after adding another item. Of course the next item is then unstyled (and so on).
If you want to see what the issue looks like:
Everything however works fine if i don't have the hash page as part of the URL (I tested this by turning the two page app into just one page for the content so that .../index.html goes straight to the content page). The css is applied to the dynamic content fine as one would expect.
Of course I have no idea why it's doing this and I suspect that it's something to do with how angular and jqm treat the hash anchor in the URL (but bare in mind I don't have much experience in both Angular JS nor jQuery Mobile).
Any help from any of the more experienced Angular JS (and jQuery Mobile) users would be greatly appreciated!
You should be creating a directive that encapsulates the list and the logic that you have for it.
As suggested in the comments to your questions, a timeout can work. If you're having issues with the element "flashing" or "flickering", you can use the ngCloak directive to deal with this.
You may also want to check out the $locationProvider configuration in your app and turn off HTML5 mode or set the hash prefix.

I'm using a Rails 6 template (Jumpstart Pro) that has the new stuff hotwire, stimulus, webpacker. It works OK for basic stuff... scaffolding new models and make CRUD forms, etc.
However one of my pages uses a vendor's javascript widget, which also requires jquery.
Neither Jumpstart Pro template nor its Forum have any up-to-date documentation or support for adding jQuery via webpacker (e.g., no support for adding jquery the "right way").
So I've added jquery to the one page that needs it via a good old fashioned script tags in the header
%script{:src => "//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"}
followed by the vendor's javascript to initialize the vendor's widget, inside $(document).ready(function(){ init_code_goes_here }); so the widget has time to load to the page.
Works: If I type the page's url into the browser "localhost:5000/cool_page" or "mydev.ngrok/cool_page", it works fine.
Broken: But clicking a link IN the app to go to the page (via link_to "cool page", "/cool_page") does not work:
jQuery is loaded (I have a little "hello world" jquery script that un-hides a div to confirm jquery is loaded)
the vendor widget does not load properly (browser console says widget object is null)
But if I then refresh the page, everything loads fine.
So the page works if "loaded" but not it reached via another page.
From this I infer that the magic behind hotwire/etc is interfering with a proper load of the page when I navigate to it.
So, the question: in a hotwire-enabled Rails 6 app, is there any way to have a nav link that, when clicked, simply tells Rails... skip hotwire shortcuts, load this page for real?
I believe your issue is just that you need to restore default (non-Hotwire) link behavior. There are 3 ways to do that.
See this answer: https://stackoverflow.com/a/68657223/2648054
In short:
1: Set the data-turbo attribute to false.
2: Set the target attribute to "_top".
3: Move the link outside any Turbo frame. Any link inside a Turbo frame, without one of the above attributes, will be handled by Turbo by default.
I am starting a jquery mobile/phonegap application. And would like to know if there is any way I can keep my code in seperate files so it is easier to manage. From all the reading I have done on jquery mobile it looks like all of your pages are in one file and are just seperated by divs like <div data-role="page" id="page-one"></div>. I guess I could try to make some type of a makefile that concatenated them all together, but it seems that most apps are pretty lengthy that they should have a solution for this. Keeping all the code in one file just seems impossible to maintain.
JQuery demo, three pages, all one source file:
http://demos.jquerymobile.com/1.1.0/docs/pages/multipage-template.html
You can just use normal links with jQuery mobile:
http://demos.jquerymobile.com/1.4.0/navigation/
It will "hijack" the link and use transitions to give you a native like animation. As Flatlineato pointed out you need to make each page confirm to the required markup, and you'll need to repeat your headers/footers etc on each included page.
Or you can use more complex solutions to dynamically change the content of your page, which can be stored in multiple files, like this other SO post:
including the header and footer in jquery mobile multiple page site
But I would also agree with Leo and say the jQuery mobile isn't the best choice for Phonegap, it's not that well optimized, and runs slower in the Phonegap webkit view than it does in native safari.
I've also switched to a custom navigation system and dropped jQM early on in my Phonegap development, but that was over a year ago, more recent versions may work better.
I think my personal API is what you are searching for:
https://github.com/charnekin/api
Demo example:
http://yopo.es/cordovapi/
jQuery Mobile allows you to have the pages in separate files. Obviously in each file must conform to the structure of the markup pages.
To point to another page in the link instead of the id you specify the correct file name. If the file then you enter multiple jquery mobile pages must also specify the id.
Have been bashing my head against the wall for a good day and a half now. Did everyone abandon old fashioned page structures to go to jQuery Mobile?
I have a webpage, tracks legislation. Main navbar goes as such:
/bills/list, /legislators/list, /committees/list
Where each link is rewritten into
index.php?category=$1&detail=$2
so /bills/list translates to
index.php?category=bills&detail=list
But when I load a page from the navbar, using an a href tag, the pages load all nice and easy using the AJAX loader, but the newly loaded pages 1. don't run scripts, and 2. don't display any formatting. This is a problem.
All the suggestions I have seen say to .bind something or .refresh or .trigger without any context of where that goes, and everything I have tried in that vein has frustrated me to no end.
Please help! And by the way, if I just data-ajax=false everything it works perfectly. But I want the quick loading that ajax gives! I just don't understand how it works and there are really no good pointers on the web I could find.
Code in this pastebin: http://pastebin.com/9jMxV0B6
You can see some artifacts of my struggling to get the thing working.
From what I gather, you shouldn't call new pages via a href, but then why the hell does jqm use href's for its nav menu? Is that supposed to call a function or something?
"But when I load a page from the navbar, using a basic old fashioned a href tag, the pages load all nice and easy using the AJAX loader, but the newly loaded pages 1. don't run scripts, and 2. don't display any formatting. This is a problem."
That happens because JQM ignores all the headers in all other pages besides the first page that loads. So if you want to do any changes to the page use page events, place them In first page.
I had problems understanding it also. Here is a link to my previous post that explains it a bit: How do I enable onload in jQuery mobile (open page both from link & load)?
Hope it clears some things for you. My recommendation for you is to do two simple pages and test simple URL functionality.
I have a local jQuery Mobile project going (inside PhoneGap, thus file:// protocol) where I sometimes need to fetch external pages (using http://) from a server where the content too are jQM pages with almost identical markup (except for the content, which is generated from a CMS).
Setting $.mobile.allowCrossDomainPages to true gives me the page, and that is all right. Going Back, however, fails. I get stuck in a place where /www/index.html is not found on the server (like, doh, of course..). Is there a way to "remember" where I came from, taking me back to the local html page I originally came from?
We just added a docs page on PhoneGap in jQuery Mobile for RC3 that should help you out quite a bit:
http://jquerymobile.com/test/docs/pages/phonegap.html
I have 2 application layouts: application.html.haml and application.mobile.haml. But when I switch from mobile to the non-mobile version the mobile layout is still used for the first load. In Firebug console I see that the non-mobile view was properly returned, however the browser and the Firebug HTML tab show the mobile layout. Any idea what's going? It's fine after a refresh.
The issue turned out to be caused by JQuery Mobile.
I found the answer here: http://jquerymobile.com/demos/1.0a3/docs/pages/docs-pages.html
JQuery Mobile doesn't do full page reloads unless it's told to, so although the full html was returned, JQuery Mobile just replaced the page portion.
The key portion from the docs is:
"It's important to note if you are linking from a mobile page that was loaded via Ajax to a page with multiple internal pages, you need to add a rel="external" or data-ajax="false" to the link. This tells the framework to do a full page reload to clear out the Ajax hash in the URL. This is critical because Ajax pages use the hash (#) to track the Ajax history, while multiple internal pages use the hash to indicate internal pages so there will be a conflicts."
Recently, I encountered a similar problem.
In my case, Rails4's turbolinks suffered. Similarly as JQuery Mobile, turbolinks only updates the body part of a full page without updating the head part of the html when an intra-site link is clicked. I simply removed the require line for turbolinks in my application.js and the problem disappeared.
