我的代码有问题，因为它目前无法运行！
问题是它没有按照我的意愿行事。这是在单击<li>列表中的链接时更改图像。
当链接被单击到链接中定义的类时，图像包装器div标签的类想要更改。
我有以下内容：
<div class="span3">
<h4 style="line-height: 0px; text-decoration: ; color: #060; display:inline;"><i class="icon-angle-right" style="display:inline;"> Our Offices</i></h4>

剧本：
$('ul li a').on('click', function(e) {
e.preventDefault();
var cl = $(this).attr('href').replace('#','');
$('.map-wrapper').removeClass().addClass('map-wrapper '+cl);
});
两个班级的CSS：
.mg-sheffield {
background-image: url(../img/map/sheffield.png);
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader( src=//ssl.gstatic.com/s2/oz/images/local/map_gradient.png, sizingMethod=scale)";

background-position: center;
height: 250px;
max-height: 250px;
max-width: 1600px;
}
.mg-dewsbury {
background-image: url(../img/map/dewsbury.png);
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader( src=//ssl.gstatic.com/s2/oz/images/local/map_gradient.png, sizingMethod=scale)";

background-position: center;
height: 250px;
max-height: 250px;
max-width: 1600px;
}
和图像包装器：
<div class="map-wrapper mg-sheffield"></div>
所以，这有一些问题。首先，单击地址时类不会更改。其次，这实际上删除了我的页面上除列表中的链接之外的所有链接的使用。这意味着导航栏等。
任何帮助，非常感谢！我无法理解......
