How to clear the input content after vue mint-ui field input so that the current input box does not lose focus

the code is as follows

<mt-field class="icon-mobile iconStyle BoxCenter verificStyle"   
          placeholder=""
          type="tel"
          v-model="mobile"
          :attr="{ maxlength: 11 }">
</mt-field>

the input content comes with the clear button. After clearing the content, the input box will lose focus. How can he not lose focus? I would like to ask whether the mint-ui clear event can be obtained
