推荐答案

ngControl，ngModel和ngFormControl是

ngControl, ngModel and ngFormControl are selectors for NgControlStatus directive, so there's no difference between them...

NgControlStatus 指令自动应用于基于控件状态(有效/无效/脏/等)设置CSS类的Angular表单.

NgControlStatus is Directive automatically applied to Angular forms that sets CSS classes based on control status (valid/invalid/dirty/etc).

NgFormControl 是绑定输入的指令模板中的 Control 类中的字段用于以编程方式创建表单字段.

NgFormControl is directive that binds input field in the template to the Control class that is used to programmatically create form fields.

NgFormControl 将现有控件绑定到DOM元素.

NgFormControl Binds an existing Control to a DOM element.
