应用场景
const ctrl = new FormControl({value: 'n/a', disabled: true});
通过 FormGroup getRawValue方法,可以获取包含disabled值
官方文档描述
/**
* The aggregate value of the{@linkFormGroup}, including any disabled controls.
*
* If you'd like to include all values regardless of disabled status, use this method.
* Otherwise, the `value` property is the best way to get the value of the group.
