you can add this.dataValue='' at the beginning of both showA () and showB ()

showA(){
      this.dataValue=''
      this.showData=this.dataA;
      this.showModal=true;
    },
    showB(){
      this.dataValue=''
      this.showData=this.dataB;
      this.showModal=true;
    },

use the setQuery method, and there is a solution in the link
