jQuery UI选项卡更改主体类

Question

I've tried the below script to no avail. I have a series of tabs at www.1tryten.com. The tabs auto rotate and change on mouseover. I'm trying to have it so that the currently active tab sets the class for the body tag. Essentially, if tab-1 is active then the body class would be tab-1 etc. Is this doable.

$(document).ready(function() {
$("#tabs").tabs({
    event: 'mouseover',
    fx: {
        opacity: 'toggle',
        duration: 'slow',
        show: function(event, ui) { $("body").addClass(ui.tab);}
    }
}).tabs('rotate', 5000, true);
});

Here's the code for the tabs

<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=""> 
    <img src="/images/mac-mini-banner.png">
        <h3>Mac Mini Security Mount.  New Mac Mini Mount.</h3>
</div> 
<div id="tabstwo" class="tabstwo ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide" style="">

Answer 1

Is this:

$("body").addClass(ui.tab);

trying to assign to body the classes of ui.tab? Because addClass expects a string as its parameter. What you should be doing is:

$("body").attr('class', $(ui.tab).attr('class'));

... assuming that ui.tab is a valid object.

Answer 2

Use the select callback:

$( ".selector" ).tabs({
   select: function(event, ui) { ... }
});

--EDIT added code from website --

$("#tabs").tabs({
event: 'mouseover',
fx: {
    opacity: 'toggle',
    duration: 'slow'
},
show: function(event, ui) { 
    $("body").addClass(className);
}

});

Answer 3

You can use the select event which gets triggered whenever you select any tab.

$(document).ready(function() {
$("#tabs").tabs({
    event: 'mouseover',
    fx: {
        opacity: 'toggle',
        duration: 'slow',
        show: function(event, ui) { $("body").addClass(ui.tab);},

    },
    select: function(event, ui) { $("body").addClass($(ui.tab).attr('class'));}
}).tabs('rotate', 5000, true);
});
