【问题描述】:
探索 Angular,我建立了一个简单的待办事项列表。
我的问题是,当我使用复选框删除一个项目时,比如最后一个项目,该项目被删除,但它上面的复选框变为“选中”。我只想能够通过复选框删除该项目,而所有其他复选框将保持未选中状态。我想不出这里的错误。模糊地,我在想我需要重置“检查”变量,但这不起作用。
angular.module('ToDo', [])
.controller('ToDoController', function ($scope, ToDoService) {
$scope.items = ToDoService.items;
$scope.checked = false;
$scope.add = function() {
ToDoService.add($scope.todo);
};
$scope.deleteItem = function() {
ToDoService.deleteItem();
};
$scope.remove = function(idx) {
this.items.splice(idx, 1);
console.log("test inside remove");
return this.items;
};
})
.factory('ToDoService', function () {
return {
items: [],
add: function(todo) {
this.items.push({todo: todo, time: new Date()});
},
deleteItem: function(idx) {
this.items.splice(idx, 1);
console.log("test inside deleteItem");
}
};
});
