我编写了一个服务来处理我的http请求,以检索,添加和删除任务。现在我面临的问题是,当我添加或删除任务时,更改不会直观显示。我必须刷新页面。
如何解决此问题。
我的角度代码(部分内容):
zazzleApp.factory('TaskService', function ($http) {
var TaskService = {};
TaskService.taskList = [];
TaskService.getTasks = function(){
$http.get('api/task/all')
.success(function(dataFromServer){
for (var i = 0; i < dataFromServer.length; i++) {
TaskService.taskList[i] = dataFromServer[i];
};
//console.log('LOGGING GET_TASK ', TaskService.taskList);
return dataFromServer;
})
.error(function(errorFromServer){
//something went wrong, process the error here
console.log("Error in getting the users from the server ", errorFromServer);
})
};
TaskService.addTask = function(pTask){
var url;
console.log(editId);
if (editId) {
url = 'api/task/update/' + editId;
} else {
url = 'api/task/create';
}
console.log("URL URL USA", url, editId);
defaultStart = new Date(clickDate);
defaultStart = defaultStart.getFullYear() + "-" + (defaultStart.getMonth() + 1) + "-" + defaultStart.getDate();
defaultStart += " 00:00:00";
console.log("YYYYYYYYYYYYY -------->>>>>", defaultStart);
defaultEnd = new Date(clickDate).addDays(1);
defaultEnd = defaultEnd.getFullYear() + "-" + (defaultEnd.getMonth() + 1) + "-" + defaultEnd.getDate();
defaultEnd += " 00:00:00";
console.log(defaultStart, defaultEnd);
pTask.color = $('#containerColorPicker').attr('ng-data-id');
return $http.post(url, {
'name': pTask.project_name,
'project_id': pTask.project_type,
'location_id': pTask.location,
'estimate_time': pTask.estimate_time || 2,
'project_client_name': pTask.project_client_name,
'url': pTask.url,
'resource_link': pTask.resource_link,
'notes': pTask.notes,
'start_time': defaultStart,
/*'start_time': pTask.start_time || defaultStart,*/
'end_time': pTask.end_time || defaultEnd,
'color': pTask.color
}, {
headers: {
"Content-Type": "text/plain"
}
})
.success(function(data, status, headers, config) {
console.log(data);
TaskService.taskList.push(data);
})
.error(function(data, status, headers, config) {
console.log("Failed to add the task to DB");
});
};
TaskService.deleteTask = function (){
if (editId) {
//console.log('logging editId in service delete task ', editId);
$http.delete('api/task/delete/' + editId, {
})
.success(function(data, status, headers, config) {
for (var i = 0; i < TaskService.taskList.length; i++) {
if(TaskService.taskList[i]._id == editId){
//index = i;
console.log ("removing the element from the array, index: ", editId, i);
TaskService.taskList.splice(i,1);
}
};
console.log('taskArray ', TaskService.taskList, editId, i);
$('#tile[ng-data-id="'+ editId +'"]').remove();
})
.error(function(data, status, headers, config) {
console.log("You were NOT succesfull in deleting a task");
});
}
};
return TaskService;
})
//START CONTROLLER
angular.module('zazzleToolPlannerApp')
.controller('CalendarCtrl', function ($scope, $mdDialog, $http, $rootScope, $timeout, User, Auth, UserService, TaskService) {
$scope.newTask = {};
$scope.newTask.project_name = "";
$scope.newTask.project_type = "";
$scope.newTask.location = "";
$scope.newTask.estimate_time = "";
$scope.newTask.project_client_name = "";
$scope.newTask.url = "";
$scope.newTask.resource_link = "";
$scope.newTask.notes = "";
$scope.newTask.color = "";
//console.log('00000000000 ', $scope.newTask); //empty
$scope.tasks = TaskService.taskList;
$scope.getTasksFromService = function () {
TaskService.getTasks(); //after this gets called, the data will be shown in the page automatically
}
$scope.getTasksFromService();
$scope.addTaskWithService = function () {
//note that you can process the promise right here (because of the return $http in the service)
TaskService.addTask($scope.newTask)
.success(function(data){
//here you can process the data or format it or do whatever you want with it
console.log("Controller: the task has been added");
$scope.tasks = [];// EMPTY THE ARRAY
TaskService.getTasks();
$scope.updateGridDataAwesome();
})
.error(function(data){
//something went wrong
console.log("Controller: error in adding task");
});
}
$scope.deleteTaskWithService = function(){
TaskService.deleteTask();
}
});
//END CONTROLLER
答案 0 :(得分:0)
这个东西在你的代码中只调用一次:
$scope.tasks = TaskService.taskList;
您的TaskService.addTask函数通过执行以下操作将新任务推送到TaskService.taskList:
TaskService.taskList.push(data);
但它并没有在任何地方再次更新$ scope.tasks。
