I am trying to add a country code where when you press on the selector under the "country" label, in the second picture, you get a list like the first picture with the country names and the flags next to it then you would be redirected to the second picture with the selector displaying the selected country flag and the country code. I tried to use
Html
<ion-row>
<ion-col>
<ion-item (click)="openSelect()">
<div class="ion-text-left">
<ion-label position="stacked">البلد</ion-label>
<ion-input [(ngModel)]="selectedCode"></ion-input>
</div>
</ion-item>
<ion-item style="display: none">
<div class="ion-text-left">
<ion-label >البلد</ion-label>
<ion-select #select1
[(ngModel)]="selectedCode">
<ion-select-option *ngFor="let c of countries" value="{{c.flag}}{{c.code}}">{{c.flag}}{{c.name}}</ion-select-option>
</ion-select>
</div>
</ion-item>
</ion-col>
.TS
#ViewChildren('select1') select1: Select;
countries: any = [
{
code: '+91',
flag: [./in.png],
name: 'India'
},
{
code: '+1',
flag: [./US.png]
name: 'America'
}
];
openSelect() {
setTimeout(() => {
this.select1.open();
}, 150);
}
for selecting the country code value you can use [value] property of ion select option
and for displaying the selected value you can use [selectedText] property of ion select in ionic 4/5
you can find official documentation here
<ion-select formControlName="country" [selectedText]="signupform.controls.country.value" name="country" #countryselect id="countryselect">
<ion-select-option *ngFor="let country of countries" [value]="country.id">
{{country.name}}
</ion-select-option>
</ion-select>

After the value is selected the value shows always empty. Working code in previous version as below. And latest version is also added below.
Am i doing wrong some where ?
IONIC previous version
<div>
<ion-select>
<ion-option *ngFor="let city of citys.options" [value]="city"> {{city}}
</ion-option>
</ion-select>
</div>
IONIC 4
<div>
<ion-select ngDefaultControl>
<ion-select-option *ngFor="let city of citys.options" [value]="city"> {{city}}
</ion-select-option>
</ion-select>
</div>
Working code if using plain html controls
<div>
<select ngDefaultControl>
<option *ngFor="let city of citys.options" [value]="city"> {{city}}
</option>
</select>
</div>
Your code is working fine when I test it - here is what's working for me:
<ion-item>
<ion-label>Cities</ion-label>
<ion-select placeholder="Select One" [(ngModel)]="selectedCity">
<ion-select-option *ngFor="let city of citys.options">{{city}}</ion-select-option>
</ion-select>
</ion-item>
<ion-item>
You selected: {{selectedCity}}
</ion-item>
In ts file:
citys = {
options: ["red", "blue", "yellow"]
}
I would suspect there is something somewhere else that is causing the component to break. Perhaps your citys object doesn't contain the data you expect.
This importing IonicModule in my components.module.ts made it to work
import { IonicModule } from '#ionic/angular';
I have two ion select and I would like to capture the value of each select from the TS when I click a button. Please help
part of code:
<ion-item>
<ion-label class="lbReward" color="dark" >Reward Type: </ion-label>
<ion-select (ionChange) = "onChange()" [ngModel] = "selectedRewardType">
<ion-option value="priceDiscount">Total Price Discount</ion-option>
<ion-option value="categoryDiscount">Category Price Discount</ion-option>
<ion-option value="freeGiftwithPrice">Sufficient Price Free Gift</ion-option>
<ion-option value="freeGiftwithMeal">Meal with Free Gift</ion-option>
</ion-select>
</ion-item>
I'm simulating something like a shopping cart using ionic 2. Basically you write the item's name and value and it's creating a list with checkbox as in the image below.
But I wanted the option only appear when selecting one of the checkboxes, and did not stay static on the screen as it is now. How can I do this?
grid calling the CheckBox:
<ion-grid>
<ion-row *ngFor="let item of produto">
<ion-item>
<ion-label (click)="clicou(item.desc)">
{{ item.desc }} {{ item.valor }}
</ion-label>
<ion-checkbox checked="false"></ion-checkbox>
</ion-item>
</ion-row>
</ion-grid>
button code part:
<button ion-button block (click)="remove()" color="danger" style="transition: none 0s ease 0s;">
<span class="button-inner">
<ion-icon name="close"></ion-icon>
Remover Selecionados
</span>
<div class="button-effect"></div>
</button>
in ts create a variable that contains the value of the checks, as an example I will use productState which will be boolean type, and create in produto a state.
you can use a ngmodel and the variable already created (productState) to validate the status of the product, and use the event (ionchange) to this
<ion-grid>
<ion-row *ngFor="let item of produto">
<ion-item>
<ion-label (click)="clicou(item.desc)">
{{ item.desc }} {{ item.valor }}
</ion-label>
<ion-checkbox (ionChange)="validState()" [(ngModel)]="productState" ></ion-checkbox>
</ion-item>
</ion-row>
in ts create a function to valid the state of products:
validState(){
let cont = 0;
for (let index = 0; index < this.produto.length; index++) {
if (this.produto[index].State){
cont++;
}
}
if(cont >=1){
this.productState = true;
}else{
this.productState = false;
}
}
and in the button we will use ngIf to validate the product status through productState
<button *ngIf="productState" ion-button block (click)="remove()" color="danger" style="transition: none 0s ease 0s;">
<span class="button-inner">
<ion-icon name="close"></ion-icon>
Remover Selecionados
</span>
<div class="button-effect"></div>
</button>

First of all that is the correct way in which a ngFor works it displays the first element first and the next items at the bottom, because whenever you insert new items inside an array it follows the top to bottom approach. So basically you want to display your array items in reverse order that should be your question
The most simple and easy solution to this is by just using reverse() on your *ngfor. In your case it would be something like this:
<ion-item *ngFor="let bill of Details.reverse()">
...
<ion-item>
or one more solution is using a custom angular pipe which you could apply on the *ngFor and sort your array in reverse order.
import { Pipe, PipeTransform } from '#angular/core';
#Pipe({
name: 'reverse'
})
export class ReversePipe implements PipeTransform {
transform(value) {
if (!value) return;
return value.reverse();
}
}
and then in your html you can use that pipe like this:
<ion-item *ngFor="let bill of Details | reverse">
...
<ion-item>
I want to make the first item in the list to be always checked but checked="true" does not seem to be working
<ion-item>
<ion-label class="label">Change City</ion-label>
<ion-select checked="true" [(ngModel)]="cityName"(ionChange)="getCity()">
<ion-option class="option" *ngFor="let city of City" value='{{city.cname}}' >{{city.cname}}</ion-option>
</ion-select>
</ion-item>
you should remove checked="true" from ion-select and try to checked from the .ts file like this:-
export class MyClass {
constructor() {
this.cityName= '**your city name**';
}
}
Note:- checked="true" not working because you used this in
ion-select so, inside the ion-select all option are occur.So it can't
get which option you want to check from ion-select.
