如果长度>0时正确显示,但长度==0时不显示,则为ng

我有一个非常简单的ng,如果它是基于数组的长度。如果长度大于零,则显示长度。如果为零,则表示为空。当长度大于零时显示,但当长度为零时不显示。有人看到我错过了什么吗?

这是我的HTML(有问题的ng if在第5行和第9行,但我想我应该把周围的HTML放在那里,以防我遗漏了一些东西):

<div class="employee-box" ng-repeat="employee in sigFigCtrl.companies[$index].employees">
    <span class="glyphicon glyphicon-edit pull-right" ng-click="sigFigCtrl.toggleEmployeeEdit($index)"></span>
    <span class="glyphicon glyphicon-remove pull-right" ng-click="sigFigCtrl.deletePerson(employee._id, $index, sigFigCtrl.companies[$parent.$index].employees)"></span>
        <div ng-show="!sigFigCtrl.companies[$index].editEmployee">
            <div ng-if="sigFigCtrl.companies[$index].employees.length > 0">
                <p><b>Name:</b> {{employee.name}}</p>
                <p><b>Email:</b> {{employee.email}}</p>
            </div>
            <div ng-if="sigFigCtrl.companies[$index].employees.length === 0">
                empty array!
            </div>
        </div>
    <div ng-show="sigFigCtrl.companies[$index].editEmployee">
        <form name="editPersonForm" ng-submit="sigFigCtrl.editPerson(employee._id, $index)">
        <div class="form-group">
            <div class="col-md-12">
                <input type="text" ng-model="sigFigCtrl.editPersonName" id="name" placeholder="Name of Employee" class="form-control" required></input>
            </div>
        </div>            <div class="form-group">
        <div class="col-md-12">
            <input type="text" ng-model="sigFigCtrl.editPersonEmail" id="name" placeholder="Email of Employee" class="form-control" required></input>
        </div>
            <button>SUBMIT</button>
        </form>
    </div>
 </div>
