firebox下怎么引用iframe

Question

   请问各位达人,firebox下怎么引用iframe?   我知道在IE中是这样访问的:      document.frames["viewphoto"].location="previewphoto.jsp";      viewphoto为iframe的name和id,
    可是在firebox下这样写,提示什么安全错误,有谁知道吗?

   我自已找到答案了,把
    document.frames["viewphoto"].location="previewphoto.jsp";    改为
    
   document.getElementById("viewphoto").contentWindow.location="previewphoto.jsp";
