How to uncheck a radio button on its second click Angular 2+

问题

I am trying to implement Radio button uncheck on second click in Angular 2+ as done here in angularjs. I have an array of objects that get displayed using *ngFor, therefore I have multiple radio button groups in one form. I need an implementation that will onlt uncheck the said radio button/ All the implementations I have tried keep checking and unchecking multiple buttons while other implementations don't work at all.

This is my current code right now. How can I implement Radio button uncheck on second click using typescript?

回答1:

You need to bind the radio value to an ngModel and either listen to the ngModelChange or click event instead of change.
