How do reset a specific field in form?-CodePudding

How to reset not the whole form, but only one field? And so that when the field is reset, it gets the value '', not null

 clear(): void {
    this.form.value.search = '';
    // this.form.reset();
    this.applyFilter();
  }

Extract the control from the form, and call reset on it with ''.

clear(): void {
    this.form.get('value')?.reset('');
    this.applyFitler();

  }

Assuming you are using HTML, what you have to do is passing an HTMLInputElemenet, like this:

clear(field: HTMLInputElement): void {
    field.value = '';
  }

And you will have to name your field like this:

<input
   type="text"
   placeholder="Total"
   #field
/>

Look the name with the #, it must be the same as you are passing in your function.

clear(formControlName): void {
  this.form.patchValue({
    formControlName : ''
   })
  }

CodePudding user response：

you can reset the form field using

this.form.get("Your Control Name").reset("");

or you can create a general function that when you call it and pass the field name as a parameter to it, will reset the field to empty string

resetFieldToEmptyString(FieldName:string) {
  this.form.get(FiledName).patchValue("")
}
