我有一个显示投资的视图+另外两个视图是注册新投资的模式,当用户单击“添加”时会显示新模式(由于有两个注册步骤,所以出现了两个模式)。我创建了工厂,该工厂在步骤1和步骤2中使用,以便保留有关注册投资的信息-当您在步骤1和步骤2之间来回切换时,它可以工作。
问题在于,在显示投资的第一个视图中,我有一个图标“ edit”,在其处理程序(编辑方法)中,我将选定的投资分配给了工厂,但是在step1视图中没有任何变化,change。
查看显示的投资:
var module = angular.module("application", []);
module.controller("investmentsController", function ($scope, investmentsFactory, newInvestmentFactory) {
$scope.edit = function (id) {
for (var i = 0; i < $scope.Investments.length; i++) {
if ($scope.Investments[i].Id == id) {
newInvestmentFactory.update($scope.Investments[i]);
}
}
$("#addInvestmentStep1Modal").modal("show");
};
});
查看注册步骤1
var module = angular.module("application");
module.factory("newInvestmentFactory", function () {
return {
investment: {
Name: "",
Description: "",
Category: "",
InterestRate: "",
Duration: "",
AmountRange: "",
Url: "",
Subscription: 0,
PaymentType: "",
Icon: ""
},
update: function (investment) {
this.investment = investment;
}
};
});
module.controller("newInvestmentStep1Controller", function ($scope, newInvestmentFactory) {
$scope.Investment = newInvestmentFactory.investment;
});
查看注册步骤2
var module = angular.module("application");
module.controller("newInvestmentStep2Controller", function ($scope, newInvestmentFactory) {
$scope.Investment = newInvestmentFactory.investment;
});
显示注册的step1视图如下
<form id="newInvestmentStep1Form" class="form-horizontal">
<div class="input-group">
<span class="input-group-addon input-group-addon-register">Name</span>
<input id="Name" name="Name" type="text" class="form-control" ng-model="Investment.Name" required title="Pole wymagane" />
</div>
将新对象分配给工厂的对象(newInvestmentFactory.investment)似乎不起作用,但是当我为工厂的某些属性分配全新的值时,例如
newInvestmentFactory.investment.Name = "name"
然后正确显示值。
最佳答案
我只能怀疑的newInvestmentFactory
方法代码。它正在将update
对象重新分配给新的investment
对象,例如investment
。通过该行,将创建新的this.investment = investment
对象,而旧的investment
松开引用。若要使investment
对象不使用update方法创建新变量,可以使用investment
/ angular.extend
方法。此方法不会创建对象的新引用,但可以确保所有对象属性都已更新。
update: function (investment) {
angular.extend(this.investment, investment);
}
