我正在尝试编写一个函数,该函数使我可以在单击按钮时删除项目,但我认为我对该函数感到困惑-我可以使用$digest吗?
$digest
HTML和app.js:
<ul ng-repeat="bday in bdays"> <li> <span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span> <form ng-show="editing" ng-submit="editing = false"> <label>Name:</label> <input type="text" ng-model="bday.name" placeholder="Name" ng-required/> <label>Date:</label> <input type="date" ng-model="bday.date" placeholder="Date" ng-required/> <br/> <button class="btn" type="submit">Save</button> <a class="btn" ng-click="remove()">Delete</a> </form> </li> </ul> $scope.remove = function(){ $scope.newBirthday = $scope.$digest(); };
要删除项目,您需要将其从数组中删除,并且可以将bday项目传递给标记中的remove函数。然后在控制器中查找项目的索引并从数组中删除
bday
<a class="btn" ng-click="remove(item)">Delete</a>
然后在控制器中:
$scope.remove = function(item) { var index = $scope.bdays.indexOf(item); $scope.bdays.splice(index, 1); }
Angular将自动检测到对bdays数组的更改并更新ng-repeat
bdays
ng-repeat

编辑:如果使用服务器进行实时更新将使用您创建的服务 $resource来管理阵列更新,同时更新服务器
$resource
