angularjs – 在解雇时显示的Bootstrap模态验证

这就是它的样子：

当表单打开时,弹出窗口根本不显示,但只有当我单击取消并且它开始消失时才会显示.

HMTL：

<form name='newGroupForm'>
    <div class="modal-body">
            <label for="groupName">Group Name:
                <input id="groupName" type="text" ng-model='newGroup.name' required>
            </label>
            <br/>
            <label for="groupDesc">Group Description:
                <input id="groupDesc" type="text" ng-model='newGroup.desc'>
            </label>
            <br/>
            <label for="groupOwner">Group Name:
                <select id="groupOwner" type="text"  ></select>
            </label>
    </div>
    <div class="modal-footer">
        <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        <button class="btn btn-primary" type="button" ng-click="submit()" ng-disabled="newGroupForm.$invalid">Create</button>
    </div>
</form>

模态控制器：

spApp.controller('newGroupCtrl',function newGroupCtrl($scope,$modalInstance,groupService){
        $scope.newGroup = {
            name:null,desc: null
        };

        $scope.submit = function(){
            $modalInstance.close($scope.newGroup);
        }
        $scope.cancel = function (){
            $modalInstance.dismiss('Cancelled group creation');
        };
    }
);
