use Google Chrome to open web site

Hi!
I built web site and hope IE and  Google Chrome can support---<asp:HyperLink ID="H1" runat="server" NavigateUrl="javascript:show_win 'A.aspx',900,500);" Target="_parent"></asp:HyperLink>.The parent open child-A.aspx and parent close.If I use IE,it work fine.But If I use Google Chrome,the parent can't be closed.I hope the parent can be closed,only show the child form.
Have any idea? Thanks a lot.
