Objects and ngFor bind (or change a toggle inside a ngFor)


#1

Hi,
I m developing a simple app. I make a request obtaining a object like this;

[{“name”:“device-1”, “code”:“00001”, “status”: true},
{“name”:“device-1”, “code”:“00001”, “status”: true},
{“name”:“device-1”, “code”:“00001”, “status”: true}]

the i use a ngFor to display each as a toggle.

I can read the toggle value inside my page controller, but i cant change the value from the controler (for example to update the device status)

what’s de correct approach?

thanks

Hello,

depending to your needs you can use property binding to manipulate from .ts side. see here https://coursetro.com/posts/code/58/Angular-4-Property-Binding-Tutorial

Or if you need to fetch the whole component then you can use @Viewchild or @Viewchildren. see here https://blog.angular-university.io/angular-viewchild/

Thanks anna,
It’s working with property binding.
