Question

I have a method that sends data to the database and can be triggered from a button using @click but I want to trigger it from another function by calling it in conditional function any one can help? the post is edited so I want to add the addPatient method called right after submitted notification is triggered in else{}

  onSubmit () {


    namefRef.value.validate()
    namelRef.value.validate()
    birthdateRef.value.validate()

    if (namefRef.value.hasError || namelRef.value.hasError || birthdateRef.value.hasError ) {
      // form has error
    }
    else if (gender.value !== 'male'&& gender.value !== 'female') {
      $q.notify({
        color: 'negative',
        message: 'You need to choose a gender'
      })

    }
    else {

      $q.notify({

        icon: 'done',
        color: 'positive',
        message: 'Submitted',

      }),

      loadinga.value = true
