我创建了一个Angular工厂,然后在控制器中使用它。工厂包含一个我试图在控制器中使用的delete方法,但是,我看到一个错误,指出未定义index。以前,在我拥有工厂之前,当控制器中的所有内容都在工作时,此功能有效,但现在不再定义index。我在这里已经阅读了很多答案,但是找不到答案。

我的代码如下所示:

js

app.factory('addressFactory', function(){

    var addressFactory = {};
    addressFactory.addressBook = [];

    addressFactory.deleteAddress = function(index) {
        addressFactory.addressBook.splice(index, 1);
        localStorage.setItem('addressBook', JSON.stringify(messages.addressBook));
    }

    return addressFactory;
})

.controller('testCtrl', ['$uibModal', 'addressFactory', function ($uibModal, addressFactory) {

     this.addressBook = addressFactory.addressBook;
     this.deleteAddress = addressFactory.deleteAddress(index);
}]);


html

<div ng-repeat="contact in ctrl.addressBook track by $index">
    <p>{{contact.name}}</p>
    <button ng-click="ctrl.deleteAddress($index)">Delete Contact</button>
</div>

最佳答案

改变这个

this.deleteAddress = addressFactory.deleteAddress(index);


对此:

this.deleteAddress = function(index){
    addressFactory.deleteAddress(index);
};
