SlideToggle在IE中不起作用

Question

这是我切换小计UL行的代码：

$('.parent').live('click',function(){

var sub = $(this).nextUntil('.subtotal').last().next();

sub.slideToggle();

});

'';

            for (var parent in cat){
                htmlstr += '<ul class="parent">';
                htmlstr += '<li>'+cat[parent]['category_name']+'</li>';
                htmlstr += '</ul>';

                var items = data['categories'][parent]['subs'];
                for (var elem in items){
                    htmlstr += '<ul class="sub">';
                    htmlstr += '<li class="one">'+items[elem]['category_name']+'</li>';
                    htmlstr += '<li class="two">'+items[elem]['today']+'</li>';
                    htmlstr += '<li class="three">'+items[elem]['mtd']+'</li>';
                    htmlstr += '<li class="four">'+items[elem]['mtd_budget']+'</li>';
                    htmlstr += '<li class="five">'+items[elem]['lymtd']+'</li>';
                    htmlstr += '<li class="six">'+items[elem]['ytd']+'</li>';
                    htmlstr += '<li class="seven">'+items[elem]['lyytd']+'</li>';
                    htmlstr += '</ul>';
                };

                // Sub-totals
                var items = cat[parent]['sub_total'];
                    htmlstr += '<ul class="sub subtotal" style="display:none">';
                    htmlstr += '<li class="one">Sub-Total</li>';
                    htmlstr += '<li class="two">'+items['today']+'</li>';
                    htmlstr += '<li class="three">'+items['mtd']+'</li>';
                    htmlstr += '<li class="four">'+items['mtd_budget']+'</li>';
                    htmlstr += '<li class="five">'+items['lymtd']+'</li>';
                    htmlstr += '<li class="six">'+items['ytd']+'</li>';
                    htmlstr += '<li class="seven">'+items['lyytd']+'</li>';
                    htmlstr += '</ul>';
            };

这适用于Firefox和Chrome，但不适用于IE。但是，如果您出于某种原因安装并打开开发人员工具栏，它将在IE中开始工作。 谢谢你的帮助。
