尝试创建一个函数来从数组中删除选定的复选框项目，但似乎无法弄清楚。我尝试过使用 splice 和 .pop() 但它不会删除我选择的项目。我认为最好的方法是使用 if 语句，但我不知道如何编写它以使其显示 true 或 false。请帮忙!!!
JS:
.controller('toDoCtrl', function($scope, toDoFactory){
//set $scope variables
$scope.tasks = toDoFactory.tasks;
$scope.removeTasks = toDoFactory.removeTasks;
})
.factory('toDoFactory', ['$http', function($http){
var toDo = {
tasks: [],
removeTasks: function(selectedTask){
angular.forEach(toDo.tasks, function(value, selectedTask){
var i = toDo.tasks.indexOf(value);
toDo.tasks.splice(toDo.tasks.indexOf(i), 1);
});
}
};
return toDo;
}])
HTML:
<button ng-click="removeTasks()">Remove</button>
最佳答案
我不太明白您是想删除所有选定的任务还是仅删除一个任务。 无论如何，你可以这样做:
JS:
app
.controller('toDoCtrl', function($scope, toDoFactory){
//set $scope variables
$scope.data = {};
$scope.data = toDoFactory.data;
$scope.removeTasks = toDoFactory.removeTasks;
$scope.removeTask = toDoFactory.removeTask;
})
.factory('toDoFactory', ['$http', function($http){
var toDo = {
data : {
tasks: [
{text: "hello world", done: false},
{text: "hello world2", done: false},
{text: "hello world3", done: false}
]
},
removeTasks: function(){
toDo.data.tasks = toDo.data.tasks.filter(function(task){
return !task.done;
});
},
removeTask: function(index){
toDo.data.tasks.splice(index, 1);
},
};
return toDo;
}]);
HTML:
<body ng-controller="toDoCtrl">
<div ng-repeat='task in data.tasks'>
<input type='checkbox' ng-model='task.done' />
<span>{{task.text}}</span>
</div>
<br/>
<button ng-click="removeTasks()">Remove</button>
</body>
