Javascript 保存/编辑跨度时显示当前日期（angularjs）

我使用

angularjs

创建了一个相当简单的任务列表，我希望在创建每个任务时节省时间，并在编辑任务时更新该时间

我想我可以用一些东西来显示当前时间，但我不知道如何在保存/编辑时显示

HTML:

---

只需在todo模型中添加一个

todoDate

属性，如

$scope.todos.push({text: $scope.todoText, done: false, editing: false, todoDate: new Date()});

并在用户更新todo对象ie

save（）

希望对您有所帮助。

当您调用保存功能添加新TODO时，只需添加createdOn字段即可

var app = angular.module('todoApp', []);
app.controller('TodoListController', ['$scope', function ($scope) {
  $scope.todos = [];
  $scope.newField = [];
  $scope.customStyle = {};
  $scope.addTodo = function () {
    $scope.todos.push({text: $scope.todoText, done: false, editing: false, created: new Date()});
    $scope.todoText = '';
  };
  $scope.remaining = function () {
    var count = 0;
    angular.forEach($scope.todos, function (todo) {
      count += todo.done ? 0 : 1;
    });
    return count;
  };
  $scope.delete = function () {
    var oldTodos = $scope.todos;
    $scope.todos = [];
    angular.forEach(oldTodos, function (todo) {
      if (!todo.done) $scope.todos.push(todo);
    });
  };
  $scope.remove = function () {
    $scope.todos.splice(this.$index, 1);
  };
  $scope.change = function (field) {
    var todoIndex = $scope.todos.indexOf(field);
    $scope.newField[todoIndex] = angular.copy(field);
    $scope.todos[todoIndex].editing = true;
    $scope.todos[todoIndex].created = new Date();
  };  
  $scope.save = function (index) {
    $scope.todos[index].editing = false;
    $scope.todos[index].created = new Date();
  };
  $scope.cancel = function (index) {
    $scope.todos[index] = $scope.newField[index];
  };
  $scope.updateVar = function (event) {
    $scope.myVar = angular.element(event.target).text();
  };
  $scope.editKeyword = function (name, index) {
    $scope.mode[index] = 'edit';
    console.log(name);
  };
}]);

$scope.save = function (index) {
    $scope.todos[index].editing = false;
    $scope.todos[index].createdOn = new Date().getTime();
};

现在，当用户编辑todo并调用change函数时，请执行以下操作

$scope.change = function (field) {
    var todoIndex = $scope.todos.indexOf(field);
    $scope.newField[todoIndex] = angular.copy(field);
    $scope.todos[todoIndex].editing = true;
    $scope.todos[todoIndex].LastModifyOn = new Date().getTime();
  };

现在，如果用户再次编辑此更新的todo，我们只需调用change函数，它将更新LastModifyOn字段

因此，通过这样做，我们可以保留两个数据，比如todo是何时创建的，最后一次是何时更新的。

那么问题出在哪里？@Jax问题是将我的想法与现有代码结合在一起。我不知道该怎么办it@RicardoPimenta你找到解决办法了吗。我的解决方案是否在任何意义上帮助了你或回答了你的问题？我也对这个问题投了赞成票。问题是，所有任务都与第一次创建任务的时间相同，即使在编辑之后，编辑后的最后一次修改将对特定的todo进行更改，而createdOn不会更改。

var app = angular.module('todoApp', []);
app.controller('TodoListController', ['$scope', function ($scope) {
  $scope.todos = [];
  $scope.newField = [];
  $scope.customStyle = {};
  $scope.addTodo = function () {
    $scope.todos.push({text: $scope.todoText, done: false, editing: false, created: new Date()});
    $scope.todoText = '';
  };
  $scope.remaining = function () {
    var count = 0;
    angular.forEach($scope.todos, function (todo) {
      count += todo.done ? 0 : 1;
    });
    return count;
  };
  $scope.delete = function () {
    var oldTodos = $scope.todos;
    $scope.todos = [];
    angular.forEach(oldTodos, function (todo) {
      if (!todo.done) $scope.todos.push(todo);
    });
  };
  $scope.remove = function () {
    $scope.todos.splice(this.$index, 1);
  };
  $scope.change = function (field) {
    var todoIndex = $scope.todos.indexOf(field);
    $scope.newField[todoIndex] = angular.copy(field);
    $scope.todos[todoIndex].editing = true;
    $scope.todos[todoIndex].created = new Date();
  };  
  $scope.save = function (index) {
    $scope.todos[index].editing = false;
    $scope.todos[index].created = new Date();
  };
  $scope.cancel = function (index) {
    $scope.todos[index] = $scope.newField[index];
  };
  $scope.updateVar = function (event) {
    $scope.myVar = angular.element(event.target).text();
  };
  $scope.editKeyword = function (name, index) {
    $scope.mode[index] = 'edit';
    console.log(name);
  };
}]);

$scope.save = function (index) {
    $scope.todos[index].editing = false;
    $scope.todos[index].createdOn = new Date().getTime();
};

$scope.change = function (field) {
    var todoIndex = $scope.todos.indexOf(field);
    $scope.newField[todoIndex] = angular.copy(field);
    $scope.todos[todoIndex].editing = true;
    $scope.todos[todoIndex].LastModifyOn = new Date().getTime();
  };
