jquery - IE - 消失的导航

Question

我正在尝试创建一个相当简单的响应式下拉菜单。在 Chrome 和 Firefox 中一切看起来都不错，但在 IE(10 及更低版本)中，菜单在某个时刻消失了。

我不太明白这个问题，我相信这与调整窗口大小时的 jQuery 有关。

我创建了一个 JSFiddle，但无法测试它，因为我的 IE10 崩溃了。

这是我的代码:

                }
            }
        }
    });

    $('.menu-primary-navigation-container').click(function() {

        if($(window).width() < 870) {

            $this = $(this);

            if($('#menu-primary-navigation').is(":visible")) {
                $this.children('ul').hide();
            } else {
                $this.children('ul').show();
            }

        }

    });

    $(window).resize(function() {

        if(!jQuery.browser.mobile) {
            if($(window).width() > 870){
                $('#menu-primary-navigation').show();
            } else {
                $('#menu-primary-navigation').hide();
            }
        }

    });

});

在此先感谢您的帮助。

现在设法解决这个问题 - 简单的解决方案是在我的 jQuery 代码中将 $(window).width() 更改为 $(document).width()。
