UntypedFormBuilder

UntypedFormBuilder is the same as FormBuilder, but it provides untyped controls.

      
      class UntypedFormBuilder extends FormBuilder {
  group(controlsConfig: { [key: string]: any; }, options: AbstractControlOptions | { [key: string]: any; } = null): UntypedFormGroup
  control(formState: any, validatorOrOpts?: ValidatorFn | FormControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): UntypedFormControl
  array(controlsConfig: any[], validatorOrOpts?: ValidatorFn | AbstractControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): UntypedFormArray

  // inherited from forms/FormBuilder
  nonNullable: NonNullableFormBuilder
  group(controls: { [key: string]: any; }, options: AbstractControlOptions | { [key: string]: any; } = null): FormGroup
  record<T>(controls: { [key: string]: T; }, options: AbstractControlOptions = null): FormRecord<ɵElement<T, null>>
  control<T>(formState: T | FormControlState<T>, validatorOrOpts?: ValidatorFn | FormControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): FormControl
  array<T>(controls: T[], validatorOrOpts?: ValidatorFn | AbstractControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): FormArray<ɵElement<T, null>>
}

Methods

group()

Like FormBuilder#group, except the resulting group is untyped.

      
      group(controlsConfig: { [key: string]: any; }, options?: AbstractControlOptions): UntypedFormGroup
Parameters
controlsConfig object
options AbstractControlOptions

Optional. Default is undefined.
Returns

UntypedFormGroup

 
      
      group(controlsConfig: { [key: string]: any; }, options: { [key: string]: any; }): UntypedFormGroup

Deprecated This API is not typesafe and can result in issues with Closure Compiler renaming. Use the FormBuilder#group overload with AbstractControlOptions instead.

Parameters
controlsConfig object
options object
Returns

UntypedFormGroup

control()

Like FormBuilder#control, except the resulting control is untyped.

 
      
      control(formState: any, validatorOrOpts?: ValidatorFn | FormControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): UntypedFormControl
Parameters
formState any
validatorOrOpts ValidatorFn | FormControlOptions | ValidatorFn[]

Optional. Default is undefined.
asyncValidator AsyncValidatorFn | AsyncValidatorFn[]

Optional. Default is undefined.
Returns

UntypedFormControl

array()

Like FormBuilder#array, except the resulting array is untyped.

 
      
      array(controlsConfig: any[], validatorOrOpts?: ValidatorFn | AbstractControlOptions | ValidatorFn[], asyncValidator?: AsyncValidatorFn | AsyncValidatorFn[]): UntypedFormArray
Parameters
controlsConfig any[]
validatorOrOpts ValidatorFn | AbstractControlOptions | ValidatorFn[]
