Angular 5 offers the capability to use mat-slide-toggle to easily display and manipulate

I am experiencing an issue with displaying data in HTML using a mat-slide-toggle. The mat-slide-toggle works correctly, but the display does not reflect whether the value is 1 (checked) or 0 (unchecked). Can anyone provide some ideas on how to resolve this?

Here is my HTML code:

<form [formGroup]="productform" class="col s12" materialize>
    <mat-slide-toggle formControlName="active" id="device" (change)="onChange($event)" [(ngModel)]="devicee[i]" (click)="onproduct()">
    </mat-slide-toggle>
    {{device}}
</form>

And here is my TypeScript code:

this.productform= this.fb.group({
    'active': new FormControl('', Validators.required),
});

populateFormProduct() {
    this.productform.setValue({
        active: this.device
    });
    console.log(this.device);
}

onChange(value) {
    if (value.isChecked === true) {
        this.device = 1; 
    } else {
        this.device = 0;
    }
}

I am setting active: this.device in order to choose this value in the HTML.

Any assistance would be greatly appreciated. Feel free to reach out with any questions!

Answer №1

After implementing the following HTML code:

<mat-slide-toggle  formControlName="active" (change)="onChange($event)" (click)="onproduct()"></mat-slide-toggle> {{device}} 

I noticed that the output resembled the image shown below:

The issue I encountered was that the device always appeared as checked. My goal was to only display it as checked when the status is 1, and unchecked when the status is 0.

Upon modifying the HTML code to:

<button formControlName="active" (click)="onChange($event) ; onproduct()"></button>

The updated result resembled the photo provided in this link:
