Очистить скрытый фрейм JavaScript

Я пытаюсь очистить данные внутри скрытого фрейма; кадр показан следующим образом

<!-- Content of the details tabs here  -->
    <div id = "tabDetail_0" class = "tab_content tab_detail" style = "display: 
    block;"><iframe id = "iframe_0" src = "https://www.tmdn.org/tmview/get- 
    detail?st13=GB500000003342197" width = "100%" height = "600px;" 
    frameborder = "0"></iframe></div></div></div> <!-- resultTabs -->

Как вы можете видеть, в HTML есть ссылка, я попытался открыть новый экземпляр веб-драйвера, перейти по ссылке и получить данные, это сработало, однако веб-сайт остановился, потому что навигация напрямую по этим ссылкам не разрешена или ограничена.
