[rdzhaox]

Is your feature request related to a problem? Please describe.

For example: emt('filedBlur', true) when ItInput loses focus.

Describe the solution you'd like

Can't tell Itinput lost focus when I want to do an assembly of Itinput and async-validator

Describe alternatives you've considered

<input @focus="handleFocus"
        @blur="handleBlur" **** />


 const handleFocus = (event: FocusEvent) => {
      focused.value = true
      emit('focus', event)
    }
    const handleBlur = (event: FocusEvent) => {
      focused.value = false
      emit('blur', event)
    }
