显示我的滑出侧边栏菜单时出现IE 9及更低版本问题

Question

我创建了一个100％宽度和高度滑出侧边栏菜单，当您单击菜单按钮时会显示该菜单。一切都很好，直到ie9及以下。发生了什么，而不是按菜单滑出菜单，菜单已经显示覆盖整个网站。

如何在ie9中正确运行？

这是我的JS，这里是完整的功能http://jsfiddle.net/pc89G/8/

 $(document).ready(function () {
    var $frm = $('#menu').hide();
var $bts = $("#menu-trigger").on('click', function () {
var $this = $(this)
    $bts.filter(".selected").not(this).removeClass('selected');
    $this.toggleClass('selected');
if ($this.hasClass('selected') && $frm.is(':visible')) {
    $frm.stop(true, true).slideUp(function () {
    $(this).slideDown()
});
    } else {
    $frm.stop(true, true).slideToggle();
    }
});
    $bts.filter('.selected').click();
$("#content, a.gn-icon-menu").click(function () {
    $bts.filter(".selected").removeClass('selected');
    $frm.slideUp();
});
    $bts.filter('.selected').hover();
    $("a.gn-icon-menu").hover(function () {
    $bts.filter(".selected").removeClass('selected');
    $frm.slideUp();
});
 });

背后的简单逻辑是这样的：http://jsfiddle.net/bC5zh/

$(function(){
    window.status=0;
    $('#toggle').click(function(){
        if(window.status==0){
            $('#slidingMenu').stop().animate({left:'0px'},500); 
            window.status=1;
        }
        else{
            $('#slidingMenu').stop().animate({left:'-100%'},500);
            window.status=0;
        }
    });
})

看看它是否启发了一个想法！ ;）
