如何在Angular 8中获取多个复选框的值

<input type="checkbox" [(ngModel)]="checkboxValues['value1']"> Checkbox 1
<input type="checkbox" [(ngModel)]="checkboxValues['value2']"> Checkbox 2
<input type="checkbox" [(ngModel)]="checkboxValues['value3']"> Checkbox 3

checkboxValues: { [key: string]: boolean } = {};

getSelectedCheckboxValues() {
  const selectedValues = [];
  for (const key in this.checkboxValues) {
    if (this.checkboxValues[key]) {
      selectedValues.push(key);
    }
  }
  console.log(selectedValues);
}
