ion-libel positon="floating" is not working with ion-input placeholder - ionic-framework

Label isn't moving when input will be focus. If input hasn't placeholder it works fine but in my case it has a placeholder. How can I fix it?
<ion-item>
<ion-label position="floating" >{{ 'enterPhoneNumber' | translate}}</ion-label>
<ion-input placeholder="Phone" name="phone" type="text" required ></ion-input>
</ion-item>

The placeholder text has to go with the ion-label tags... Please refer the official docs.
<ion-item>
<ion-label position="floating"> Phone </ion-label>
<ion-input required [(ngModel)]="enterPhoneNumber" type="text"></ion-input>
</ion-item>

<ion-card-content>
<ion-item>

[(ngModel)]="account.email"

<span>Email address is not valid.</span>
</div>
<ion-item>
<ion-label floating>Password</ion-label>
<ion-input
[(ngModel)]="account.password"
type="password"
name="password"
#password="ngModel"
required></ion-input>
</ion-item>
</ion-card-content>

The Email address is not valid. is not showing. I would really appreciate your help.
With the Ionic version 3.19.1, when you change something in the html of a component, the changes does not reflect. You have to change something at a .ts and save.

How to slide to the top of the page in ionic 3

I am developing a SIgnup page in ionic 3 and the no of fields are 10.
SO I am using a p tag to show validation and when the user hits submit I want to take him all the way up to the start of the page which has my header and all.How can I achieve this?I have tried everything.
Below is my code:
<ion-content padding class="label-cl green-bg acct-sct item-row" style="position:fixed">
<h2 class="center-col">Create An Account</h2>
<form #f="ngForm" (ngSubmit)="signUp(f)">
<ion-item>
<ion-label floating>Username</ion-label>
<ion-input type="text" name="name" ngModel required></ion-input>
</ion-item>
<p style="color:red;text-align: left" *ngIf="usernameError">Invalid Username</p>
<ion-item>
<ion-label floating>Email</ion-label>
<ion-input type="email" name="email" ngModel required></ion-input>
</ion-item>
<p style="color:red;text-align: left" *ngIf="emailError">Invalid E-mail</p>
<ion-item>
<ion-label floating>Password</ion-label>
<ion-input type="Password" name="password" ngModel required></ion-input>
</ion-item>
<p style="color:red;text-align: left" *ngIf="passwordLengthError">Invalid Password</p>
<ion-item>
<ion-label floating>Confirm Password</ion-label>
<ion-input type="Password" name="confirm_password" ngModel required></ion-input>
</ion-item>
<div class="button-inline">
<button ion-button class="yellow-cl" [disabled]="!f.valid">Submit</button>
</div>
</form>
</ion-content>
It has more fields but I am showing only these just for the sake of clarity.
Thanks in advance.
Add the below code to your .ts file
import { Component, ViewChild } from '#angular/core';
import { Content } from 'ionic-angular';
#Component({...})
export class SignUpPage{
#ViewChild(Content) content: Content;
signUp() {
this.content.scrollToTop();
}
}
We used Angular's #ViewChild annotation to get a reference to the ionic content component which has the method scrollToTop().

Proper way to handle fields with same names in Forms

I met strange bug in my application. I template driven form with two addresses two fill:
<ion-list>
<ion-list-header color="secondary">From
<button ion-button icon-only item-right clear small (click)="usePosition($event)">
<ion-icon name="locate"></ion-icon>
</button>
<button ion-button icon-only item-right clear small (click)="searchAddress(true,$event)">
<ion-icon name="search"></ion-icon>
</button>
<button ion-button icon-only item-right clear small (click)="useHome(true,$event)">
<ion-icon name="home"></ion-icon>
</button>
</ion-list-header>
<div>
<ion-item>
<ion-label floating>Street Address*</ion-label>
<ion-input type="text" [ngModelOptions]="{standalone: true}" [(ngModel)]="createRequest.legs[0].addressFrom.Street"

Zip Code*(5 digits)

</ion-item>
</ion-list>
I tried to use [ngModelOptions]="{standalone: true}" but without any result.
At some moment for unkonown reason two addresses start duplicate each other and even stranger thing in this case that using predefined data(like in useHome() method) didn't give effect. I know that answer is near, so will appreciate any help in advance.
Use unique name attributes for your form fields, this way each form field will be evaluated as separate one. I see some inconsistency in the use of the name attribute, all should have a name attribute, as well as #someName="ngModel" if you want to use validation. Loose the ngModelOptions altogether. I would separate these and do for example From... and To... for the name attribute:
For example the two fields for Street:
<ion-input name="FromStreet" #FromStreet="ngModel"
[(ngModel)]="createRequest.legs[0].addressFrom.Street" required>
</ion-input>
and
<ion-input type="text" name="ToStreet" #ToStreet="ngModel"
[(ngModel)]="createRequest.legs[0].addressTo.Street" required>
</ion-input>
This way all fields are unique.
This line of code:
[ngModelOptions]="{standalone: true}"
Is telling the form that your input element is NOT included as part of the form's data. You only want to do that with controls that you don't want to track on submittal. For example, say you have a checkbox that simply opens or closes a part of the user interface. You don't want that part of the submitted data, so you would use the standalone option so it "stands alone" from the form and its data.

ionic2: How to do calculations in form?

I have a form with product rate and quantity inputs. I need to calculate the value (rate * quantity) and assign the value to amount input field.
Please find the code snippet below:
<form [formGroup]="additemForm" (ngSubmit)="submit(additemForm.value)" >
<ion-row>
<ion-col>
<ion-list inset>
<ion-item>
<ion-label>Product :</ion-label>
<ion-select formControlName="product">
<ion-option *ngFor="let product of productArray" value="{{product.code}}" selected="false">{{product.name}}</ion-option>
</ion-select>
</ion-item>
<ion-item>
<ion-label>QUANTITY :</ion-label>
<ion-input type="number" formControlName="qty"></ion-input>
</ion-item>
<ion-item>
<ion-label>RATE:</ion-label>
<ion-input type="number" formControlName="rate"></ion-input>
</ion-item>
<ion-item>
<ion-label>Value :</ion-label>
<ion-input type="number" formControlName="value"></ion-input>
</ion-item>
</ion-list>
</ion-col>
</ion-row>
<ion-row>
<ion-col class="signup-col">
<button ion-button class="submit-btn" type="submit" [disabled]="!additemForm.valid">Submit</button>
<button ion-button type="button" (click)='cancel()' >Cancel</button>
</ion-col>
</ion-row>
</form>
You need to use [(ngModel)] for this.
<ion-item>
<ion-label>QUANTITY :</ion-label>
<ion-input type="number" formControlName="qty" [(ngModel)]="quantity"></ion-input>
</ion-item>
<ion-item>
<ion-label>RATE:</ion-label>
<ion-input type="number" formControlName="rate" [(ngModel)]="rateValue"></ion-input>
</ion-item>
<ion-item>
<ion-label>Value :</ion-label>
<ion-input type="number" formControlName="value" [(ngModel)]="rateValue * quantity"></ion-input>
</ion-item>
Now, still amount input field will be edible after this. And changing this value will affect the other 2 input values also. You can disable the input, so it will appear as a read-only input. This worked in my code.
