I found this question because I wanted "starts with" behavior, and now all the browsers seem to implement "contains".

let wrdlimit = prefix =>
{ let elm = mydatalist.firstElementChild;
  while( elm )
  { if( elm.value.startsWith( prefix ))
    { elm.removeAttribute('disabled');
    } else
    { elm.setAttribute('disabled', true );
    }
    elm = elm.nextElementSibling;
  }
}
