Hello together
I'm very new to mobile app development and JS frameworks such as Angular as
well.
I didn't do much in learning by reading or making tutorials but started
with Apache Cordova from where I "fell" into Ionic, starting with an
example project and trying to move forward using trial and error and google
as my best friend for what I needed ad the moment.
So Ionic led me to Angular.js - and therefore I've not really an idea how
Angular should be used or what should be done which way. Therefore some
basic questions from my side:
So, on the "left" side I have my services.js with the data models which
rely on "localStorage" and are empty first and need an "update" call to
update localStorage from local array copies.
On the "middle" side i have my app.js which does basic initialisation and
populates some local storage on first launch (user activation) or
initialises some stuff if already activated and helds local copies of
localStorage (some tokens).
On the "right" side I have my views which for example show data from the
through localStorage initialised models and too can cause changes of data
in already initialized model through user interaction as for example in the
following scenario:
In the "new entry" view I've 3 selects which show data from the models with
ng-repeat. The first one is an organisation selection and the 2nd/3rd ones
are cat/type which are dependent from the selected org.
So if I change the org, the cats/types models become invalid and need to be
refreshed from localStorage with the data from the selected org.
I tried calling a function switchOrganisation() in my models on org. change
but even failed accessing it alltough the model or even the function was
defined in the scope in the controller.
Then the second "problem": When I change the org, localStorage and
theoretically the local variables in .run() should be changed too. 1st I
can do manually on change but 2nd I don't know how to access but it isn't
that bad since atm I don't need them anymore after activation.
But anyway it is always some kind of inconsistency respectively I have to
manually take huge care that all the datas are consistent and match to each
other.
When for example I even change the user, atm 4 models change
(organisations, types, categories and an entries list). This has to be done
manually or what I would do atm is like at activation, set the localStorage
tokens and call $window.location.reload(true);.
Maybe my approach isn't good but for that's too late now anyway.....
Then like in the MVC principle, when changing the model, the view should
change too (change org -> types/cats selects should be refreshed too). But
I don't think this will work with ng-repeat...??
I wasn't able to check this since I wasn't able to correctly access the
switchOrganisation-functions of the types and cats models in the org.
select's onchange.
About scopes: How for example to access a control from .run() or from a
model? Or isn't this possible and/or shouldn't be done anyway?
And why does even the following not work:
<ion-content class="padding">
<script type="text/javascript">
function lalala() { //organisations_onChange() {
//alert(val);
alert("sdfsdf");
}
</script>
<select onchange="lalala();">
.....
Thank you very much for any help and advices!
Best regards
