I have written an ionic application and would like to know how(if) i can validate the ionic app. Much like validating HTML with W3C.
Is there any way possible to run a validation check on the app.
I have tried to run the application in the browser and run a google chrome local html validation, however the directives are still visible and haven't been generated to html.
I don't believe there is a way to validate the Ionic HTML in the same way you validate the HTML in W3C validator.
however the directives are still visible and haven't been generated to html
Probably a bit of confusion here.
1. AngularJS directives will always be visible "as is" in the HTML code, they will not transform to anything. It's AngularJS itself to use them in its special way.
2. Ionic components are build with custom HTML tags, which means, for example will not transform to anything else. All Ionic custom tags are defined in ionic.css file.

I have to customize a platform designed in ASPX and AngularJS.
I only have access to the HTML and CSS code, I do not have access to the AngularJS controller.
I want to add a small JavaScript script, but I encounter a problem when I integrate it on the platform.
I cannot detect when the page is loaded.
If I use the javascript (window.onload) or jQuery ($(document).ready) functions, it doesn't work.
Since I don't have access to the AngularJS controller, do I have a way of knowing when the page is loaded?
Thank you

I am working with a serverless HTML so JavaScript cannot load other html content. I was wondering if there is an example of pulling the template from the DOM so that I can pack all my views into a single HTML file (i.e. without having to use string templates).
Would this work?
I am working with AngularJS 1.7.5 rather than the newer Angular 2.
I need it to work with Outlook/IE.
I was thinking of just getting the .InnerHTML of some base element. Advice, notes, concerns?
I am creating a single page app (mobile/desktop) using AngularJS. Based on the limited knowledge I have of AngularJS, I think the routing for the apps/websites is based on urls and $location/$location.path directive is used. However, in mobile or desktop apps, there is no browser. So how does AngularJS routing work in this case if views need to be switched?
Thanks
If you are talking about an Angular application by itself, it will always need something to be interpreted by something. Angular is written in JavaScript which means it will have to be interpreted by something which understands JavaScript. I am using the word interpreted instead of compiled, because JavaScript is not a compiled language.
But then how does something that interprets JavaScript display it on my screen you ask? For this you'll need a bit of background information.
The DOM
This is where we got to the Document Object Model DOM. From W3c:
The Document Object Model is a platform- and language-neutral
interface that will allow programs and scripts to dynamically access
and update the content, structure and style of documents. The document
can be further processed and the results of that processing can be
incorporated back into the presented page. This is an overview of
DOM-related materials here at W3C and around the web.
To dumb the quote above down:
you have a document (web page) which is being displayed and the DOM allows you to change this document which is being displayed.
JavaScript Engine
The link between JavaScript and the DOM is provided by an Engine. Every browser uses a JavaScript Engine. For example Chrome uses the V8 JavaScript engine. From an introduction of V8:
JavaScript is most commonly used for client-side scripting in a
browser, being used to manipulate Document Object Model (DOM) objects
for example. The DOM is not, however, typically provided by the
JavaScript engine but instead by a browser. The same is true of
V8—Google Chrome provides the DOM. V8 does however provide all the
data types, operators, objects and functions specified in the ECMA
standard.
How does this translate to your question?
Everything that wants to display a JavaScript application, needs to have a JavaScript Engine and a DOM. This could be a browser like Chrome, but could also be any other application.
A simple explanation of what a router does, is change the DOM to display different "documents". So plainly said: any application, be it a mobile or desktop application, which has a DOM understands how to use Angular's routing system.
Outside the browser means only application you are speaking about?. angular is tied to HTML pages in general. So its a framework for managing(not exactly appropriate word) the html pages to make them into Single Page Applications so that browser does not need to reload the entire the web application on request of a single page, it helps to invoke the html pages into the main html pages, this makes the application not to reload the entire, but to make available requested pages. this is where the routing comes.
Angular will work just fine there. In fact there is an Ionic project that is based on top of angular. E.g. if you are using Cordova, then the app is rendered inside a browser (or at least with the browser engine). So as far as I know it will behave exactly the same way with the exception of user not being able to type in URL or click back/forward.
Moreover I build an application for browser where I do not user URL as much as possible. E.g. I transition only between states and don't have direct url's in my application at all. Of course I need to support to the extent that a user can type in the url, but the ui-router does that on it's own if you map routes properly. But it seems much more beneficial not to rely on the urls at all for SPA (for internal stuff as you still have the edit url as I said before).
I am trying to understand how AngularJS framework works. For that reason I want to debug angularjs framework code (not my application code) however I am not able to figureout how angular gets attached to DOM and starts compilation. Can anybody help me to findout which is piece of code or lines in angularjs script file from where AngularJS kicks off and starts parsing and compilation.
you need to read the application bootstrap section in the angular docs, but basically angular will take your html, starts the compilation processes, at which point it will start replacing any custom html or directives with the matching templates, no scopes or bindings done just yet, html might not even be in dom yet, afer that angular goes to linking process, where bindings are made, scopes are created and html gets attached to DOM, thats the short version you can find it here

I've working on an AngularJS solution, in which ngSanitize is used to sanitize markup received from an Ajax call.
This markup will occasionally contain iframe tags.
When I test the app with iframe tags, ngSanitize seems to remove them.
Do you have any suggestions as to how to get ngSanitize to ignore iframe tags and allow them to render?
Looks like this isn't possible using the current version of angular-sanitize.
An issue has been logged, to ask for the whitelists to be made extensible, so we can add more tags to them, such as .
Meantime, Brandy Isom has written a fix to enable such customization, and sent it as a pull-request to the Angular team. You can use this fix in the meantime.
(Hopefully it gets incorporated into the next version.)
