问题描述

如何在代码中将Angular 2控件标记为脏?

How do I mark an Angular 2 Control as dirty in my code?

当我这样做时:

control.dirty = true;

我收到此错误:

Cannot set property dirty of #<AbstractControl> which has only a getter

推荐答案

您应使用markAsDirty方法，如下所示:

You should use the markAsDirty method, like this:

control.markAsDirty();

这还会将所有直接祖先标记为肮脏，以维护模型.

This will also mark all direct ancestors as dirty to maintain the model.
