My application is driving some devices identified by their ID.

The app contains a tab-page with 2 tabs: Left and Right. I basically followed the template of ionic. Both Left and Right need to know the ID.

When I click on a button, the routing system leads me to /tab-page/:ID. Then the default tab is Left. The tab-page reads the ID from

this.activatedRoute.snapshot.paramMap.get('ID');  (in ionViewWillEnter).

I want to pass the ID to the Left and to the Right elements.

My first approach was the following:

• the tab-page writes the ID in a Global variable
• Left reads the ID from the Global variable in ionViewDidEnter

Issue: sometimes, Left is entered before the tab-page has read the params so it reads an old value from the Global.

Second approach:

• the tab-page published an Event after reading the ID: this.events.publish(‘new_ID’, id);
• Left subscribes to the event to get the ID

ngOnInit(){
this.events.subscribe(‘new_id6_index’, (data)=>{ console.log(…); });
}

Issues: sometimes, the event is published once but read twice by Left, as if Left was created twice. These two instances of Left block each other. In app.routing.module, the preloadingStrategy (PreloadAllModules or default) has no impact.

Third approach

• same as the second one, but I add a timer before the event is published. This is supposed to ensure that Left has opened.

    setTimeout(() => {this.events.publish('new_id6_index', aa);},200);

It is not really clean but it works.

Question: what is the best practice in this domain?

Thanks!

We are using ion-toggle and wanting to show a message when the toggle is enabled. For this we are using (ionChange) event.

However there are some scenarios where we want to programmatically set the value of the toggle (when loading the form) and do not want the message to show.

Is there a way to detect this in the event, or to update the toggle without triggering the change event?

Dear all,

while writing a style guide / design system for our Ionic-based applications, I was wondering about the intention behind the various named colors in Ionic. Okay, names like “success”, “warning” and “danger” are easily understandable, similar for “dark”, “medium”, “light”.

But what about “primary”, “secondary” and “tertiary” (which - if I remember correctly - was introduced only recently with v4). Especially when looking at the default theme. From a UX perspective, I would imagine that “primary” should be used for the most important action on a page (“CTA”), however, this is the default when no other color is defined at a button. besides, “secondary” and “tertiary” are no less prominent.

Is there any documentation about the intentions behind this structure?

Cheers,

Heiner

Hi there,

I like Ionic PWA: No need for app installation, just calling a page on a webserver and the app is running on the smartphone in the browser.

My app needs for some reason the ip address of the webserver it is running on. So, the solution needs to work on server side while acting the php interpreter before it got send out to the smartphone browser.

On Php I get the string of the ip address with

getHostByName(getHostName()); // returns something like ‘192.168.0.20’

How to transfer this result string from php into the Ionic PWA app?

Do I have to rename the index.html into a index.php and play around with value-attributes that get the string injected/binded like

<input hidden [ngModel]=“whatever” value="<?= getHostByName(getHostName()); ?>">

For example, <ion-input type="file"></ion-input> gives me this error "Type ‘“file”’ is not assignable to type ‘TextFieldTypes’."
This happens despite the fact that the ionic documentation allow to give to a ion-input the type=file.

I’ve tried also<ion-input file /> I have another error "Type ‘{ file: true; }’ is not assignable to type ‘IonInput’.

I don’t understand how to use a simple ion-input field with type file.
