我正在玩离子和本地存储。我正在搞乱离子示例应用程序来定制它,我遇到了麻烦。基本上主页列出了项目。一旦用户进入该项目,他们就可以添加到任务列表中。
要在主页上创建项目,用户打开模态并输入信息(标题,日期等...),然后将项目存储在本地存储中。 item数组有一个用于任务列表的嵌套数组。
一旦用户进入某个项目,他们就可以打开一个添加任务的模态。提交后,任务被推送到嵌套数组,该数组运行良好并输出:
但是,当用户返回列出所有项目的主页时,只会重复一些空对象(在本地存储中查找对象是完美的)。
我的列表控制器和内部列表控制器:
.controller('ProfileCtrl', function ($filter, $scope, $stateParams, $timeout, $ionicModal, Eventers) {
var createEventer = function(eventerId, eventerTitle, eventerVenue, eventerDay, eventerMonth, eventerYear, eventerDate) {
var newEventer = Eventers.newEventer(eventerId,eventerTitle, eventerVenue, eventerDay, eventerMonth, eventerYear, eventerDate);
$scope.eventers.push(newEventer);
Eventers.save($scope.eventers);
}
$scope.eventers = Eventers.all();
$ionicModal.fromTemplateUrl('new-event.html', function(modal) {
$scope.eventerModal = modal;
},
{
focusFirstInput: false,
scope: $scope
});
////////////////////////////////
$scope.date = new Date();
console.log($scope.date);
////////////////////////////////
$scope.createEventer = function(eventer, index) {
var eventerId = localStorage.clickcount;
var eventerTitle = eventer.title;
var eventerVenue = eventer.venue;
var eventerDay = eventer.day;
var eventerMonth = eventer.month;
var eventerYear = eventer.year;
var eventerDate = $scope.date;
if (eventerId,eventerTitle, eventerVenue, eventerDay, eventerMonth, eventerYear, eventerDate) {
createEventer(eventerId,eventerTitle, eventerVenue, eventerDay, eventerMonth, eventerYear, eventerDate);
$scope.eventerModal.hide();
eventer.title = "";
eventer.venue = "";
eventer.day = "";
eventer.month = "";
eventer.year = "";
}
console.log(eventer);
};
})
和我的内心控制者:
.controller('ProfileInnerCtrl', function ($scope, $stateParams,$ionicModal, $timeout, Eventers) {
$scope.eventer = Eventers.get($stateParams.eventerId);
$ionicModal.fromTemplateUrl('new-task.html', function(modal) {
$scope.eventerModal = modal;
},
{
focusFirstInput: false,
scope: $scope
});
$scope.createTask = function(task) {
$scope.eventer.tasks.push({
title: task.title
});
console.log(task.title);
Eventers.save($scope.eventer);
task.title = "";
$scope.eventerModal.hide();
};
$scope.newTask = function() {
$scope.eventerModal.show();
};
$scope.closeNewTask = function() {
$scope.eventerModal.hide();
}
$scope.completionChanged = function() {
Eventers.save($scope.eventers);
};
})
--------编辑:添加工厂-------
.factory('Eventers', function() {
/**/
return {
all: function() {
var eventerString = window.localStorage['eventers'];
if (eventerString) {
return angular.fromJson(eventerString);
}
return [];
},
save: function(eventers) {
window.localStorage['eventers'] = angular.toJson(eventers);
},
newEventer: function(eventerId, eventerTitle,eventerVenue , eventerDay, eventerMonth, eventerYear, eventerDate) {
return {
id: eventerId,
title: eventerTitle,
venue: eventerVenue,
day: eventerDay,
month: eventerMonth,
year: eventerYear,
date: eventerDate,
tasks: []
};
},
get: function(eventerId){
var hell = window.localStorage['eventers'];
var eventers = JSON.parse(hell);
for (var i = 0; i < eventers.length; i++) {
if (parseInt(eventers[i].id) === parseInt(eventerId)){
console.log(eventerId);
return eventers[i];
}
}
return null;
}
}
});
添加图片:前2个显示主页和本地存储,然后添加任务。添加任务和主页后,最后2个显示本地存储
答案 0 :(得分:1)
好吧,当你创建一个新任务时,你会在localStorage中保存$ scope.eventer,它只包含标题。
为什么不在$ scope.eventer中推送整个任务对象?
$scope.createTask = function(task) {
$scope.eventer.tasks.push(task);
...
编辑:
添加任务后,localStorage中的求偶器不是数组,因此ng-repeat接受对象中的每个键。
尝试Eventers.save([$ scope.eventer]);对于测试,但是你必须重新考虑整个过程,当你在阵列中有多个对象时会怎样?你会以这种方式失去旧的
