如果你想删除DOM的所有复选框，那么你可以借助javascript

来完成

removeAllSelectedCheckBoxes() {
    var checkedBoxes = document.querySelectorAll('input[type=checkbox]:checked');
    for(let i=0; i<checkedBoxes.length; i++) {
      checkedBoxes[i].parentNode.removeChild(checkedBoxes[i]);
    }
}

注意：javascript代码适用于打字稿。

Angular 2：单击该div外部的按钮时选择所有复选框
