如何使用ng-click從數(shù)組中刪除項(xiàng)目或?qū)ο?？我正在嘗試編寫一個(gè)函數(shù)，使我能夠在單擊按鈕時(shí)刪除項(xiàng)目，但我認(rèn)為我對(duì)該函數(shù)感到困惑 - 我使用了$digest嗎？HTML和app.js：<ul ng-repeat="bday in bdays">   <li>     <span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>     <form ng-show="editing" ng-submit="editing = false">       <label>Name:</label>       <input type="text" ng-model="bday.name" placeholder="Name" ng-required/>       <label>Date:</label>       <input type="date" ng-model="bday.date" placeholder="Date" ng-required/>       <br/>       <button class="btn" type="submit">Save</button>       <a class="btn" ng-click="remove()">Delete</a>     </form>   </li></ul>$scope.remove = function(){   $scope.newBirthday = $scope.$digest(); };
