我尝试了以下脚本无济于事。我在www.1tryten.com上有一系列标签。选项卡会自动旋转并在鼠标悬停时更改。我正在尝试使用它，以便当前活动的选项卡为body标签设置类。本质上，如果tab-1处于活动状态，则主体类将为tab-1等。这是否可行。
$(document).ready(function() {
$("#tabs").tabs({
event: 'mouseover',
fx: {
opacity: 'toggle',
duration: 'slow',
show: function(event, ui) { $("body").addClass(ui.tab);}
}
}).tabs('rotate', 5000, true);
});
这是标签的代码
<div id="tabs" class="tabs-bottom ui-tabs ui-widget ui-widget-content ui-corner-all">
<div id="tabsone" class="tabsone ui-tabs-panel ui-widget-content ui-corner-bottom" style="">

最佳答案
这是：
$("body").addClass(ui.tab);
试图分配给主体的ui.tab类？因为addClass需要一个字符串作为其参数。您应该做的是：
$("body").attr('class', $(ui.tab).attr('class'));
...假设ui.tab是有效的对象。
