Chinaren同学录的这段代码也是IE only的吗?

menuoptions=new Array(
new Array('个人设置|#'),
new Array('&&收件箱<font color=red style="font-size:10px"></font>&|js:openit_mail()|200'),

new Array('&&个人资料&|http://profile.chinaren.com/zhs/login.jsp?group=alumni&url=http://alumni.chinaren.com/class/class_register.jsp?classuuid=2817034545008357241|200'),


new Array('&&修改密码&|http://log2.chinaren.com/zhs/chpass.jsp|200'),
new Array('&&绑定手机&|http://alumni.chinaren.com/class/user_mobile.jsp|200'),
new Array('学生生涯|#'),
