Angular 在这里发生了一些奇怪的事情。
我有一个带有编辑按钮的详细信息视图。当我按下编辑按钮时，我将对象传递给编辑视图。在编辑表单上有几个下拉框。我第一次单击编辑按钮时，一切都加载得很好。所有下拉列表都选择了正确的值。当我在编辑表单上按取消时，我会返回到详细信息视图。当我什么都不做并在详细信息视图上再次按下编辑按钮时，下拉列表根本没有选择值！但是下拉菜单确实有项目。
这怎么可能？我没有对数据做任何事情！
详细信息视图和编辑视图都是指令：
在customerDetail的模板中：
<div>
Here all the details of the customer
<button ng-click="ShowCustomerEditForm()">Edit</button>
</div>
<customer-edit
visible="showCustomerForm"
customer = "customer">
</customer-edit>
指令客户编辑：
app.directive("customerEdit", function (CustomerService, CountryService) {
return {
restrict: 'E',
templateUrl: '/Customer/Add',
scope: {
customer: '=',
visible: '=',
onCustomerSaved: '&'
},
link: function (scope, element, attributes) {
CustomerService.getAllAcademicDegrees().then(function (response) {
scope.academicDegrees = response;
});
CustomerService.getAllGenders().then(function (response) {
scope.genders = response;
});
CountryService.getAllCountries().then(function (response) {
scope.countries = response;
});
scope.$watch('customer', function (newValue) {
if (newValue && newValue.Id > 0) {
scope.customer.originalCustomer = {};
angular.copy(scope.customer, scope.customer.originalCustomer);
}
});
scope.customerFormSubmit = function () {
if (scope.customer.Id > 0) {
editCustomer();
}
else {
addCustomer();
}
}
scope.hideCustomerForm = function (restoreOriginal) {
if (restoreOriginal) {
angular.copy(scope.customer.originalCustomer, scope.customer);
}
scope.visible = false;
}
// Private functions
function editCustomer() {
var editCustomer = createCustomer(scope.customer);
editCustomer.Id = scope.customer.Id;
CustomerService.editCustomer(editCustomer).then(editCustomerSucceeded);
scope.hideCustomerForm(false);
}
function editCustomerSucceeded(response) {
var uneditedCustomer = _.findWhere(scope.customers, { Id: response.Id });
angular.copy(response, uneditedCustomer);
}
function addCustomer() {
var newCustomer = createCustomer(scope.customer);
CustomerService.addCustomer(newCustomer).then(function (response) {
scope.onCustomerSaved({ customer: response });
scope.hideCustomerForm(false);
});
}
}
}
});
我现在尝试解决这个问题 6 个小时，但我只是不明白，我变得非常绝望。我只是不知道如何解决这个问题以及是什么原因造成的。我真的希望有人可以帮助我..
