Angular uibModal, Resolve, Unknown Provider
提问by Thomas
I am trying to expose a "generic" modal - using Angular's $uibModal- through a service. Here is the definition of that service:
我正在尝试通过服务公开一个“通用”模式——使用 Angular 的$uibModal。这是该服务的定义：
angular.module('app').service('CustomModalService', ['$uibModal', function ($uibModal) {
var openCustomModal = function (size, title, message) {
var actionToPerformOnConfirm = action;
var modalInstance = $uibModal.open({
templateUrl : 'templates/CustomModal.html',
size: size,
resolve: {
title: title,
message: message
}
});
};
return {
openCustomModal: openCustomModal
};
}]);
Nothing too complicated, above. However, it is not working. If I remove the resolveproperty from the object, the service works; however, if I include the resolveproperty, I get the Unknown Providererror originating from that property.
没什么太复杂的，上图。但是，它不起作用。如果我resolve从对象中删除该属性，则该服务将起作用；但是，如果我包含该resolve属性，则会收到源自该属性的Unknown Provider错误。
The documentation for the resolveproperty reads:
该resolve物业的文件如下：
(Type: Object) - Members that will be resolved and passed to the controller as locals; it is equivalent of the resolve property in the router.
（类型：对象）- 将作为本地人解析并传递给控制器的成员；它相当于路由器中的解析属性。
The objective is to be able to provide a template for the modal that utilizes these properties in its DOM, e.g. :
目标是能够为在其 DOM 中使用这些属性的模态提供模板，例如：
<div ng-controller="CustomModalController">
<div class="modal-header">
<h3 class="modal-title">{{title}}</h3>
</div>
<div class="modal-body">
{{message}}
</div>
<div class="modal-footer">
<button class="ad-button ad-blue" type="button" ng-click="confirmAction()"></button>
<button class="ad-button ad-blue" type="button" ng-click="cancelAction()"></button>
</div>
</div>
What am I missing that is causing this error to be thrown?
我错过了什么导致抛出这个错误？

You have two problems:
你有两个问题：
- You need to define the controller in your modal config
- Your resolve object needs to be a map of
string:function, wherestringis the name of the dependency that will be injected into your modal's controller, andfunctionis a factory function that will be used to provide that dependency when the controller is instantiated.
- 您需要在模态配置中定义控制器
- 你的决心对象需要是地图的
string：function，其中string是将被注入到你的模态的控制依赖的名称，function是将用来提供这种依赖性当控制器被实例化一个工厂函数。
