I have the following code that should set the checked value to false on click:
@Component({
template: `
<input type="checkbox" [checked]="checked" (change)="onChange()">
`
})
export class AppComponent {
checked = false;
onChange() {
setTimeout(() => {
this.checked = false;
}, 1000)
}
}
The problem is that if we click on the input and we wait for a second, it'll stay checked. Why is this happening? Why Angular doesn't change it to false again?
Long story short Angular checkboxes are just broken : Issue
If you however want to achive this effect i will recommend you to create your own custom component that will act the same way as a checkbox.
Here is one more fun example of Checkbox madnes try to interact with both "With track by" and "No track by" blocks and see what happens.
I think you can do that easily by using [(ngModel)]="checked". Your code is working in the stackblitz link. Please check that. Here is my code given below.
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `
<input type="checkbox" [checked]="checked" [(ngModel)]="checked" (change)="onChange()" name="horns">
<label for="horns">Horns</label>
`,
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
checked = false;
onChange() {
setTimeout(() => {
this.checked = false;
}, 2000)
}
}
[checked]="checked" is not working. Actually, every single time I have used ngModel to display and manipulate data. It works almost like real-time. :-(in angular you can manipulate dom using view child and element ref
first of all you need to import viewchild and elementRef in your component
app.component.ts
import { Component, VERSION } from "@angular/core";
import { ViewChild, ElementRef } from "@angular/core";
@Component({
selector: "my-app",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"]
})
export class AppComponent {
@ViewChild("checkBox") el: ElementRef;
onChange() {
setTimeout(() => {
this.el.nativeElement.checked = false;
}, 100);
}
}
app.component.html
<input type="checkbox" #checkBox (click)="onChange()">
