I am trying to check my radio button with zero value by default. I am trying to use the [checked]='true' attribute. But that does not work.

<input type="radio" name="unitTrusts-pnl" id="unitTrusts-pnl0" class="with-gap" [value]="0" [(ngModel)]="unitTrustsPnl"  [checked]='true'>

推荐答案

由于按钮已绑定到变量，请尝试设置该变量:

Since the buttons are bound to a variable, try setting the variable instead :

unitTrustsPnl = 0;
