.toggleClass 不工作？

Question

我正在尝试让页脚 class 在使用 Jquery 和 bootstrap visible/hidden class 展开最小化的导航侧边栏时显示es。切换功能适用于另外两个元素和另一个具有相同 ID (!) 的元素，只是不适用于 ID 为“#filler”的页脚 class :S

我的代码：

$(document).ready(function(){/* off-canvas sidebar toggle */

$('[data-toggle=offcanvas]').click(function() {
$(this).toggleClass('visible-xs text-center');
$(this).find('i').toggleClass('glyphicon-chevron-right glyphicon-chevron-left');
$('.row-offcanvas').toggleClass('active');
$('#lg-menu').toggleClass('hidden-xs').toggleClass('visible-xs');
$('#xs-menu').toggleClass('visible-xs').toggleClass('hidden-xs');
$('#filler').toggleClass('hidden-xs').toggleClass('visible-xs');
$('#btnShow').toggle();
});
});

HTML:

                <ul class="nav hidden-xs" id="lg-menu">
                    <li class="active">
                        <a href="#" class="three-d">

Answer 1

尝试将页脚的 ID 从填充符更改为页脚。然后确保也在你的js中改变它。 <footer class="text-center hidden-xs" id="footer">

$('#footer').toggleClass('hidden-xs').toggleClass('visible-xs');

很确定这就是您要实现的目标。查看我的 fiddle 看看 http://jsfiddle.net/a4mqw9ox/

尽管如此，您仍然需要将 js 作为您的填充 ID
