推荐答案
您在嵌入式html中做错了。我将您的源代码更改为：
You did wrong in your embedded html. I changed your source code to:
template:'<div>User Name<input type="text" ng-model="reg.Username" name="Username" class="form-control" required ng-minlength="5" ng-maxlength="20" /></b></div>' +
'<br><div ng-messages="regForm.Username.$error" style="color:maroon" role="alert">' +
'<div ng-message="required">Enter User Name</div>' +
'<div ng-message="minlength">User name is too short</div>' +
'<div ng-message="maxlength">User Name is too long</div></div>',
它在这里起作用： http://plnkr.co/edit/onlfdhraHipjezcgIg7f?p=预览
