I have a sub menu on a website, but if I click on the sub menu it is not loading on any mobile but it is working fine on laptop

<iframe name="MainFrame" id="MainFrame" src="home.aspx" height="800" width="100%" frameborder="0" style="background:white; margin-top:20px;  position:relative; z-index:auto; white-space:nowrap;"></iframe>

<a href="#">Active</a>
                <ul id="mnuActive" class="submenu">
                    <li><a href="#" onclick="load_menu_link('../home/');" >My page</a></li>

function load_menu_link(url) {
               window.frames['MainFrame'].location.replace(url);
           }
