主干.js IE8 appendChild(） 错误

典型的"在Chrome/FF中工作，但不能在IE中工作"的故事。IE9似乎处理得很好。

IE 控制台中唯一显示的是：
SCRIPT65535：对方法或属性访问的意外调用。jquery.min.js，第 3 行字符 32461

下面是跟踪错误的 IE 探查器的屏幕截图。

这是我的 Nav.js 文件中的代码：

    // Build nav menu array
    var navLinks =  [ {"style" : "home"         ,"page" : ""                    ,"name" : "Home"                ,"tier" : 1     ,"icon" : "home"}, 
              {"style" : "job-trans"    ,"page" : "view/jobTransaction" ,"name" : "Job Transactions"    ,"tier" : 1     ,"icon" : "barcode"},
              {"style" : "job"          ,"page" : "view/job"            ,"name" : "Jobs"                ,"tier" : 1     ,"icon" : "inbox"},
              {"style" : "user"         ,"page" : "view/user"           ,"name" : "Users"               ,"tier" : 1     ,"icon" : "user"},
              {"style" : "report"       ,"page" : "page/report"         ,"name" : "Reports"             ,"tier" : 2},// ,"icon" : "signal"},
              {"style" : "customer"     ,"page" : "view/customer"       ,"name" : "Customers"           ,"tier" : 2}
            ];
    var jobSearchAttr = $.browser.msie ? "value='"Enter Job #'" data-browser='"IE'" style='"font-size: 16px'"" : "placeholder='"Enter Job #'"";
    var userSearchAttr = $.browser.msie ? "value='"Enter User ID'" data-browser='"IE'" style='"font-size: 16px; padding-left:0;'"" : "placeholder='"Enter User ID'"";
    // Sort array elements into buttons and dropdowns with appropriate elements
    var i, t1LinkArray = [], t2LinkArray = [], t2ClassArray = [];
    for (var i = 0; i < navLinks.length; i++) {
        switch(navLinks[i]["tier"]) {
            case 1:
                t1LinkArray.push( "<li class='"" + navLinks[i]['style'] + "'"><a href='"#/" + navLinks[i]['page'] + "'"><i class='"icon-" + navLinks[i]['icon'] + " icon-white'"></i> " + navLinks[i]['name'] + "</a></li>" );
                break;
            case 3:
                t2LinkArray.push( "<li class='"" + navLinks[i]['style'] + "'"><a href='"#/" + navLinks[i]['page'] + "'">" + navLinks[i]['name'] + "</a></li>" );
                t2ClassArray.push( navLinks[i]['style'] );
                break;
        }
    }
    // Create Navbar View
    NavView = Backbone.View.extend({
        // Define View template
        template: _.template( $('#navbarTemplate').html() ),
        initialize: function () {
            this.render();
        },
        render: function () {
            // Call the template and pass data object
            this.$el.html( this.template({ t1LinkArray : t1LinkArray, t2LinkArray : t2LinkArray, t2ClassArray : t2ClassArray }) );
        },
    });
    var nav = new NavView({ el:$('nav') }); 

为什么这仅在IE 7/8中崩溃。
