如何禁用反作用窗体角度的窗体控制?

你必须把它加到 formState -第1个参数 fb.control :

this.step1 = this.fb.group({
  'name': this.fb.control({value: '', disabled: true}, [Validators.required, Validators.minLength(1), Validators.maxLength(50)])
});

我不确定这是否有效

'name': [{
  value: '',
  disabled: true
}, [Validators.required, Validators.minLength(1), Validators.maxLength(50)], disabled: true]

但我相信这是真的

'name': new FormControl([{
  value: '',
  disabled: true,
  validators: [Validators.required, Validators.minLength(1), Validators.maxLength(50)], disabled: true]
})

disabled:true 为了这个。

this.step1 = this.fb.group({
      name: [{value:'name',disabled:true}, [Validators.required, Validators.minLength(1), Validators.maxLength(50)]],
      lastname: [{value:'last name',disabled:true}, [Validators.required, Validators.minLength(1), Validators.maxLength(50)]]
})
