如何以编程方式取消选中单选按钮

Question

我有下面发布的单选按钮，我想知道如何使用类型脚本以编程方式取消选中它。我尝试了以下操作，我将 averageHeight 的值设置为 false，但这并没有取消选中单选按钮。请让我知道如何实现

html:

<div id="idRadioButtonForAverageHeightDivision">
                <input [value]="0" [(ngModel)]="iOperationPasser.averageHeight" name="radioGroupForOperations" type="radio" clrCheckbox  (change)="toggleShowAverageHeight()"  [(checked)]="averageHeight"/>
                    <label id="operation-average-height">
                        {{ "SITE.AREAS_OF_COVERAGE_FOR_THRESHOLD.OPERATION_AVERAGE_HEIGHT" | translate }} 
                        <button class="btn btn-sm btn-icon" (click)="showInformation('SERVICE_DIST_4_AGRI')">
                            <clr-icon shape="help-info" class="is-solid"></clr-icon>
                        </button>
                    </label>
            </div>

收音机输入的默认行为是取消选中。

您可以使用绑定或使用 angular 来控制它的属性，只需访问属性 checked 并更改它。

喜欢：

<input type="radio" value="exm" #radio />


// access the input with local variable on the template
<button (click)="radio.checked=false">
    uncheck
</button>

或-------------------------

<input type="radio" value="exm" [checked]="term" />


// now this is toggling the checked value, so it will check and uncheck - depend on the status
<button (click)="toggle()">
    uncheck
</button>


TS FILE ----------------------
public term: boolean = false

toggle(){
  this.term = !this.term

}

因为您要访问值属性，它看起来几乎相同：

<input type="radio" [value]="value" />


TS FILE ----------------------
// any change of the value will change it in the template. Since it's not a text input - ngModel is useless .
public value: string = 'Value here'
