I have a list of checkboxes inside ngFor. Each checkbox has its own parent div. I want checkboxes to be checked once the div clicked.
Here is my code.
<div *ngFor="let option of qustions; let i = index" (click)="doCheckboxCheck()">
<input type="checkbox" [value]="option.value">
<span>Checkbox {{i}}</span>
</div>
You could assign an Angular template reference variable to the <input>
element and toggle it's checked
property in the <div>
's click
or mouseup
event.
Now this could modify the default behavior of checkbox's own click event, so you could bind the [checked]
toggle to <input>
too.
<div
class="checkbox-container"
*ngFor="let option of questions; let i = index"
(mouseup)="inputCheckbox.checked = !inputCheckbox.checked"
>
<input
#inputCheckbox
class="checkbox"
type="checkbox"
[value]="option.value"
(mouseup)="inputCheckbox.checked = !inputCheckbox.checked"
>
<span>Checkbox {{ option.value }}</span>
</div>
Working example: Stackblitz
We can change the state of the checkbox on div click by passing the index to the even handler. Please refer to the link below which is having a working solution,
import { Component } from "@angular/core";
@Component({
selector: "my-app",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"]
})
export class AppComponent {
questions = [
{ value: "Checkbox-1", checked: false },
{ value: "Checkbox-2", checked: false },
{ value: "Checkbox-3", checked: false },
{ value: "Checkbox-4", checked: false },
{ value: "Checkbox-5", checked: false }
];
doCheckboxCheck(index: number): void {
this.questions[index].checked = !this.questions[index].checked;
}
}
Template:
<div *ngFor="let option of questions; let i = index" (click)="doCheckboxCheck(i)">
<input type="checkbox" [value]="option.value" [checked]="option.checked">
<span>Checkbox {{i}}</span>
</div>
