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?

解决方案

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