HTML

<input ng-model="contact.name" type="text">
<button ng-click="Add()">Add</button>

<ul ng-repeat="contact in contactList">
    <li>{{ contact.name }}</li>
</ul>

JS

$scope.contactList = [
    {name: 'cris'},{name: 'vlad'}
;]

$scope.Add = function() {
    $scope.contactList.push($scope.contact)
    $scope.contact = ""
}

似乎我可以添加1项,但在第二个我得到此错误：
