I have a downpayment form that have two inputs. One for dollar amount and one for percentage. I also have a slider that changes the percentage.
<div class="form-group">
<label for="">Down Payment</label>
<div class="flex-row d-flex">
<input class="form-control" type="text" v-model="downPaymentComputed" />
<input class="form-control" type="text" v-model="dpPercent">
</div>
<div class="mt-3 pt-4">
<vue-slider
v-model="dpPercent"
:tooltip="'always'"
:min="0"
:max="100"
:tooltip-formatter="formatter1"
></vue-slider>
</div>
</div>
in the script
let app = new Vue({
el: '#app',
delimiters: ['${', '}'],
components: {
VueSlider: window['vue-slider-component']
},
data: {
formatter2: v => `$${('' + v).replace(/\B(?=(\d{3})+(?!\d))/g, ',')}`,
formatter1: '{value}%',
payment:null,
downPayment: {{ property.price*0.2 }},
dpPercent:'20',
price: {{ property.price }}
},
computed:{
downPaymentComputed(){
return this.price*(this.dpPercent/100)
}
},
In this configuration when I use the slider or enter the percentage, the downpayment changes. But when I enter new downpayment, nothing happens.
How do I bind so that when I change either the downpayment or the percent or the slider all inputs get updated?
EDIT: Thanks Phil, you pointed me in the right direction. I binded the values and then used on:change methods to update the other values
<input class="form-control" type="text" v-on:keyup="updateDP()" v-model="price" />
<input class="form-control" type="text" v-on:keyup="updatePercent()" v-model="downPayment" />
<input type="text" class="form-control" v-on:keyup="updateDP()" v-model="dpPercent">

You're missing value on each of your inputs. When a checkbox or radio input is selected value is what gets added to your v-model array

I added Vue Stripe on my vue2 Project and I have 2 similar errors on my code :
Property 'redirectToCheckout' does not exist on type 'Vue | Element | (Vue | Element)[]'.
Property 'publishableKey' does not exist on type 'CombinedVueInstance<Vue, unknown, unknown, unknown, Readonly<Record<never, any>>>'.
I followed the documentation on their website and everything is similar as their code so I don't know why I have those errors.

Do I need to import something else or ?
A couple of things are happening here.
First, keep in mind that if you want to access the publishableKey in the template then you should add it in the object that you're returning in the data() function.
Try to do some checking before accessing checkoutRef, try this:
if (this.$refs.checkoutRef) {
this.$refs.checkoutRef.redirectToCheckout()
}
I would like to make the value ****here****of the input id="inputWorkload" dynamic and related to the value of inputDuration (newTask.duration * 2 )
How to do it with Vue js?
<div class="col-sm-2">
<div class="form-group">
<label for="inputDuration">Duration (H)</label>
<input class="form-control" id="inputDuration" min="4" step="4" type="number" v-model="newTask.duration">
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<label for="inputWorkload">Workload</label>
<input disabled class="form-control" id="inputWorkload" value="****here****">
</div>
</div>
Add an on change event to the duration:
<input class="form-control" id="inputDuration" min="4" step="4" type="number" v-model="newTask.duration" onchange="myFunction()">
Then write some JavaScript which gets the value of the duration on change and updates the workload value based on that.
<script>
function myFunction() {
var inputDurationValue = document.getElementById("inputDuration").value;
document.getElementById("inputWorkload") = inputDurationValue;
}
</script>
With a watcher. Something like this.
data: {
//define your #inputWorkload variable , let's say "workload"
},
watch: {
newTask: {
handler(val){
this.workload = val.duration * 2;
},
deep: true
},
}
// in your template
<input disabled class="form-control" id="inputWorkload" :value="workload">
How to show different component on radio button select.
<input type="radio" name="book" value="One" checked="checked">
<input type="radio" name="book" value="Round">
<div> // this should show show default, One is selected
<p>Value One</p>
</div>
<div> // this should show show on radio change to Round selected
<p>Value Round</p>
</div>
How about something like this?
new Vue({
el: '#app',
data: {
x: 'one',
},
});
<script src="https://rawgit.com/vuejs/vue/dev/dist/vue.js"></script>
<div id="app">
<input type="radio" v-model="x" value="one">
<input type="radio" v-model="x" value="two">
<div v-show="x === 'one'">One</div>
<div v-show="x === 'two'">Two</div>
</div>
i have done it with javascript .onclick it calls each function which hides & show element vice versa
function rdone(){
document.getElementById('one').style.display ='block';
document.getElementById('round').style.display ='none';
}
function rdround(){
document.getElementById('round').style.display = 'block';
document.getElementById('one').style.display ='none';
}
#round{
display:none;
}
<input type="radio" name="book" value="One" checked="checked" onclick="rdone();">
<input type="radio" onclick="rdround();" name="book" value="Round">
<div id=one> // this should show show default, One is selected
<p>Value One</p>
</div>
<div id=round> // this should show show on radio change to Round selected
<p>Value Round</p>

I am new for angular 2. I have a page where we can edit details of customer profile. How to enable save button if any property of has been changed. I know it is possible in angular1 by using $watch.
It is simple. dirty check your form if you are using #angular/forms.
create form
export class HeroDetailComponent4 {
heroForm: FormGroup;
states = states;
constructor(private fb: FormBuilder) {
this.createForm();
}
createForm() {
this.heroForm = this.fb.group({
name: ['', Validators.required ],
street: '',
city: '',
state: '',
zip: '',
power: '',
sidekick: ''
});
}
}
HTML:
<h2>Hero Detail</h2>
<h3><i>A FormGroup with multiple FormControls</i></h3>
<form [formGroup]="heroForm" novalidate>
<button (click)="submit()" [disabled]="!heroForm.dirty" type="button">Submit</button>
<div class="form-group">
<label class="center-block">Name:
<input class="form-control" formControlName="name">
</label>
</div>
<div class="form-group">
<label class="center-block">Street:
<input class="form-control" formControlName="street">
</label>
</div>
<div class="form-group">
<label class="center-block">City:
<input class="form-control" formControlName="city">
</label>
</div>
<div class="form-group">
<label class="center-block">State:
<select class="form-control" formControlName="state">
<option *ngFor="let state of states" [value]="state">{{state}}</option>
</select>
</label>
</div>
<div class="form-group">
<label class="center-block">Zip Code:
<input class="form-control" formControlName="zip">
</label>
</div>
<div class="form-group radio">
<h4>Super power:</h4>
<label class="center-block"><input type="radio" formControlName="power" value="flight">Flight</label>
<label class="center-block"><input type="radio" formControlName="power" value="x-ray vision">X-ray vision</label>
<label class="center-block"><input type="radio" formControlName="power" value="strength">Strength</label>
</div>
<div class="checkbox">
<label class="center-block">
<input type="checkbox" formControlName="sidekick">I have a sidekick.
</label>
</div>
</form>
use heroForm.dirty to check whether form data is changed. it will set to true if any control inside heroForm has been changed.
<button (click)="submit()" [disabled]="!heroForm.dirty" type="button">Submit</button>
Refer angular docs for more info
you can use form control validation for it.
some thing like this in html template:
<form fxLayout="column" [formGroup]="form">
<mat-form-field class="mb-1">
<input matInput [(ngModel)]="userProfileChangeModel.firstName" placeholder="نام"
[formControl]="form1.controls['fname']">
<small *ngIf="form1.controls['fname'].hasError('required') && form1.controls['fname'].touched"
class="mat-text-warn">لطفا نام را وارد نمایید.
</small>
<small *ngIf="form1.controls['fname'].hasError('minlength') && form1.controls['fname'].touched"
class="mat-text-warn">نام باید حداقل 2 کاراکتر باشد.
</small>
<small *ngIf="form1.controls['fname'].hasError('pattern') && form1.controls['fname'].touched"
class="mat-text-warn">لطفا از حروف فارسی استفاده نمائید.
</small>
</mat-form-field>
<mat-card-actions>
<button mat-raised-button (click)="editUser()" color="primary" [disabled]="!form1.valid" type="submit">
ذخیره
</button>
</mat-card-actions>
</form>
and like this in ts file:
this.form = this.bf.group({
fname: [null, Validators.compose([
Validators.required,
Validators.minLength(2),
Validators.maxLength(20),
Validators.pattern('^[\u0600-\u06FF, \u0590-\u05FF]*$')])],
});
if:
[disabled]="!form1.valid"
is valid save button will be active
bast regards.
You can use disabled option like below :
<button [disabled]="isInvalid()" type="button" (click) = "searchClick()" class="button is-info">
<span class="icon is-small">
<i class="fa fa-search" aria-hidden="true"></i>
</span>
<span>Search</span>
</button>
you can create isInvalid() in your ts file and check if that property is empty or not and return that boolean value
and for hide button on a state you can use *ngIf in line directive.
This worked for me, pls try.
In your html,
<input type="text" [ngModel]="name" (ngModelChange)="changeVal()" >
<input type="text" [ngModel]="address" (ngModelChange)="changeVal()" >
<input type="text" [ngModel]="postcode" (ngModelChange)="changeVal()" >
<button [disabled]="noChangeYet" (click)="clicked()" >
<span>SUBMIT</span>
</button>
In your component
export class customer implements OnInit {
name: string;
address: string;
postcode: string;
noChangeYet:boolean = true;
constructor() {}
changeVal(){ // triggers on change of any field(s)
this.noChangeYet = false;
}
clicked(){
// your function data after click (if any)
}
}
Hope this is what you need.
Finally I resolved this issue.
import { Component, Input, Output, OnInit, AfterViewInit, EventEmitter, ViewChild } from '#angular/core';
#Component({
selector: 'subscribe-modification',
templateUrl: './subscribe.component.html'
})
export class SampleModifyComponent implements OnInit, AfterViewInit {
disableSaveSampleButton: boolean = true;
#ViewChild('sampleModifyForm') sampleForm;
ngAfterViewInit() {
setTimeout(() => {
this.sampleForm.control.valueChanges.subscribe(values => this.enableSaveSampleButton());
}, 1000);
}
enableSaveSampleButton() {
console.log('change');
this.disableSaveSampleButton = false;
}
}
HTML
<button id="btnSave" class="btn btn-primary" (click)="save()" />
