I want to add validation to a modal window, I need a behavior in which when the OK button (form submission) is clicked, validation would take place, and if the result is negative, the window should not close
my modal
<b-modal
size="lg"
id="modalToRepair"
title="Add Problem"
title-class="font-18"
centered
body-class="p-4"
no-close-on-backdrop
no-close-on-esc
#ok="onClickModalRepair"
>
<div class="row">
<div class="col-lg-12">
<div class="form-group row">
<label class="col-4 col-form-label">
Repair Problem
<span class="text-danger">*</span>
</label>
<div class="col-8">
<input
v-model="theProblem"
type="text"
class="form-control"
placeholder="Input problem"
name="theProblem"
:class="{
'is-invalid': typesubmit && $v.theProblem.$error
}"
/>
<div
v-if="typesubmit && $v.theProblem.$error"
class="invalid-feedback"
>
<span v-if="!$v.theProblem.required">Requred field.</span>
</div>
</div>
</div>
</div>
</div>
</b-modal>
and my methods
Vue.js
methods: {
onClickModalRepair() {
this.typesubmit = true;
this.$v.$touch();
if (this.$v.$invalid) {
this.$bvModal.show("modalToRepair"); // not work - modal hide
//code for not hide this modal
return;
}
}
},
validations: {
theProblem: {
required
}
}
is it possible?
The method used in the #ok event, is passed an event, which you can call .preventDefault() on, if you want to prevent the modal from closing.
onClickModalRepair(bvModalEvt) {
this.typesubmit = true;
this.$v.$touch();
if (this.$v.$invalid) {
bvModalEvt.preventDefault();
return;
}
}
You can see an example of this on the docs.

The problem is that after 5 seconds, though the value of the variable changes, the alert is still visible.
I checked some similiar questions, and have seen this happening when bootstrap's javascript wasnt loaded. But for me, Bootstrap v5.0.1 JS is being loaded from the CDN and appears in the sources tab in Chrome.
Try to change the function inside of setTimeout to arrow function like this
setTimeout(() => { // code here })
The this inside of setTimeout(function () => {}) reference to the wrong context (the function itself) instead of the Vue component.
The arrow function doesn't have the this binding so when you use the arrow function the this keyword will reference the Vue component and change the state.

vue.js, how can I make my section hide only after the submit button is pressed. right now the section disappears after I press one letter. I want the V-if and V-else to activate only after the user has submitted their request. or if routing the results on to a different page would easier id like to go that route also.

import { ref } from 'vue';
import env from '#/env.js';
import MovieSection from '#/components/MovieSection.vue';
import SecondMovieSection from '#/components/SecondMovieSection.vue'
export default {
components: {
MovieSection,
SecondMovieSection
},
setup () {
const search = ref("");
const movies = ref([]);
const SearchMovies = () => {
if (search.value !== "") {
fetch(`API_HERE`)
.then(response => response.json())
.then(data => {
console.log(data)
movies.value = data.Search;
})
}
}
return {
search,
movies,
SearchMovies
}
}
}
Well, it closes once you type a single character because search is a model - it updates on every keypress you do within input it's bound to. What you wanna do instead is hide form based on whether you have entries in your movies array or not, so try changing v-if="search !== ''" to v-if="!movies.length"
When I click the button on my modal with an empty field on my input its give me an undefined value on my console. And when I put a value on my input and click the button it is adding to my database. The problem is even the empty field or the undefined value are also adding to my database and the sweetalert is not working. I want to prevent the empty field adding to my database and prevent the undefined. Can somebody help me?

The easiest way to stop this is adding data check. And condition check at top of your method.category_description !== undefined. Btw, move your e.preventDefault() to top too.
First of all do this:
- <button type="submit" #click="category_description !== undefined ? addCategory : ''" class="btn btn-primary"> Add Category </button>
+ <button type="submit" #click.prevent="addCategory" class="btn btn-primary"> Add Category </button>
and then in addCategory:
addCategory() {
if (!this.category_description) {
return;
} else {
// do your stuff here
}
}
When you are clicking on Add Category button, it is triggering the addCategory along with your validation method.
The return value of validation method has no impact on triggering of addCategory.
This issue can be handled in following ways.
Call addCategory only when there is some valid data
<button type="submit" #click="category_description != undefined ? addCategory() : ''" class="btn btn-primary"> Add Category </button>
Call the validation method inside addCategory and then proceed.
I have a form with two radio buttons which is enabled only when a checkbox is checked.
My problem is when I check the checkbox and click the submit button, the radio value is not getting posted. But after I click on the checkbox and then click on one of the radio buttons then the value is posted.
How to fix this issue?
This is the code I have tried:
HTML
<form [formGroup]="filterProductTargetForm" (ngSubmit)="onSubmitFilterDataList(filterProductTargetForm.value)">
<div class="row">
<div class="col-md-10">
<input type="checkbox" [ngModel]="isProductTypeChecked" formControlName="checkProductType" (change)="onProductTypeChange($event)" />
<label>Select A or B</label>
</div>
</div>
<div class="row">
<label class="col-md-2 uni-label"></label>
<div class="col-md-10 prduct-type-radio">
<fieldset [disabled]="!isProductTypeChecked">
<input type="radio" [checked]="isProductTypeChecked == true" value="A" formControlName="productTypeSelected" [(ngModel)]="productTypeSelected">
<span>B</span>
<br>
<input type="radio" value="B" formControlName="productTypeSelected" [(ngModel)]="productTypeSelected">
<span>B</span>
</fieldset>
</div>
</div>
<button class="uni-button def" [disabled]="!filterProductTargetForm.valid">OK</button>
</form>
TS
ngOnInit() {
this.filterProductTargetForm = this.formBuilder.group({
'checkProductType': '',
'productTypeSelected': ''
});
}
public filterProductTargetForm: FormGroup;
public isProductTypeChecked = false;
onProductTypeChange(event: any) {
this.isProductTypeChecked = !this.isProductTypeChecked;
if(!this.isProductTypeChecked)
this.filterProductTargetForm.controls['productTypeSelected'].reset();
}
First remove all ngModel from your template when using reactive forms.
When the checkbox value changes, in your onProductTypeChange function set the productTypeSelected value
this.filterProductTargetForm.controls['productTypeSelected'].setValue('A');
Working StackBlitz DEMO
I have such Angular 5 template-driven form made with ng-bootstrap modal
<button type="button" class="close" (click)="activeModal.close()"
aria-label="Close">
<span aria-hidden="true">x</span>
</button>
<form (ngSubmit)="editMode ? editBoard(board) : addBoard(newBoard.value)"
#newBoard="ngForm"
id="newBoard"
name="newBoard"
novalidate>
<div class="form-group">
<label>Board name</label>
<input type="text"
*ngIf="editMode"
class="form-control"
name="name"
#name="ngModel"
[ngModel]="board?.name"
(input)="changeName(board, name.value)"
placeholder="Enter a board name (required)"
autofocus
required>
<div *ngIf="name.touched && name.errors">
<div *ngIf="name.errors.required" class="alert alert-danger">Board name is required</div>
</div>
</div>
</form>
I want to use it for create and for edit. While adding and editing it's Ok but when I'm closing empty form modal (open and close) with "Close" or "x" buttons I have an error when input into field:
ERROR TypeError: Cannot set property 'name' of undefined
Here is a function to open a modal
public openBoardModalToAdd(): void {
const ref = this.modal.open(BoardModalComponent,
{
keyboard: false,
backdrop: 'static',
size: 'lg'
}
);
ref.componentInstance.board = {name: ''};
ref.result.then(board => this.boards = [...this.boards, board]);
}
How I can fix this?
