Javascript angularjs：禁用单选按钮，而不是实际禁用它

我需要禁用一个单选按钮，但仍然能够通过它的标签。实际上，似乎将其设置为禁用会使其脱离选项卡旋转

因此，我做了以下工作：

<input type="radio" class="appear-disabled" ng-keypress="suppressKeyboard($event)" name="contestedDataYes" ng-model= REDACTED.contestedData ng-value="'Y'" ng-checked="REDACTED.contestedData === 'Y'" aria-label="Yes">&nbsp;Yes&nbsp;
<input type="radio" class="appear-disabled" ng-keypress="suppressKeyboard($event)" name="contestedDataNo" ng-model= REDACTED.contestedData ng-value="'N'" ng-checked="REDACTED.contestedData === 'N'" aria-label="No">&nbsp;No&nbsp;

.appear-disabled {
 opacity: .5;
 pointer-events: none;
}

$scope.suppressKeyboard = function(event) {
 var keyCode = event.keyCode;

 // 32 = space, 13 = enter
 if (keyCode == 13 || keyCode == 32) {
   event.preventDefault ? event.preventDefault() : (event.returnValue = false);
 }
};

这会使单选组在视觉上显示为已禁用，并防止鼠标单击单选按钮，但不会阻止在单选按钮上单击Tab键并单击空格或enter键以切换单选按钮

为什么suppressKeyboard功能不阻止键盘输入？

尝试将ng keypress更改为ng keydown，然后在功能中执行以下操作：

HTML

按键->可防止->在以下情况下触发：按键 按键->可防止->在：按住键时触发 按键->无法阻止->释放按键时触发

为什么不使用ng disabled？因为你不能在一个禁用的元素上使用tab键你只想使用click？css会禁用鼠标点击交互。我还需要禁用键盘交互。检查答案中的修改是否满足用例。

<input type="radio" class="appear-disabled" ng-keydown="suppressKeyboard($event)" name="contestedDataYes" ng-model= REDACTED.contestedData ng-value="'Y'" ng-checked="REDACTED.contestedData === 'Y'" aria-label="Yes">&nbsp;Yes&nbsp;
<input type="radio" class="appear-disabled" ng-keydown="suppressKeyboard($event)" name="contestedDataNo" ng-model= REDACTED.contestedData ng-value="'N'" ng-checked="REDACTED.contestedData === 'N'" aria-label="No">&nbsp;No&nbsp;

$scope.suppressKeyboard = function(event) {
    var keyCode = event.keyCode;
    // 32 = space, 13 = enter

    if (keyCode == 13 || keyCode == 32) {
       //event.preventDefault ? event.preventDefault() : (event.returnValue = 
       false);
      event.preventDefault();
     }
 };
