我正在使用 AJAX 加载 JQuery UI 选项卡。
我有 3 个级别的嵌套 UI 选项卡：
- 垂直的
- 水平的
- 水平的
大多数东西只有 2 级深，但有些是 3 级。问题是第 3 级。我跟着这个：
http://benalman.com/code/projects/jquery-bbq/examples/fragment-jquery-ui-tabs/
但它不包括选项卡的嵌套。
页面的布局是这样的：
<script type="text/javascript">
var tabs;
var tab_a_selector;
var tab_a_vertical_selector;
$(function() {
$("#menuTabs").tabs({
ajaxOptions: {
cache: false
}
}).addClass("ui-tabs-vertical ui-helper-clearfix");
$("#menuTabs li").removeClass('ui-corner-top').addClass('ui-corner-left');
$(".ui-tabs-vertical .ui-tabs-nav").removeClass("ui-tabs-nav").addClass("ui-tabs-nav-vert")
$("#menuItem0").tabs();
$("#menuItem1").tabs();
//...
/* -- enables Back button for nested tabs -- */
// The "tab widgets" to handle.
tabs = $('.tabs');
// This selector will be reused when selecting actual tab widget A elements.
tab_a_selector = 'ul.ui-tabs-nav a';
tab_a_vertical_selector = 'ul.ui-tabs-nav-vert a';
// Enable tabs on all tab widgets. The `event` property must be overridden so
// that the tabs aren't changed on click, and any custom event name can be
// specified. Note that if you define a callback for the 'select' event, it
// will be executed for the selected tab whenever the hash changes.
tabs.tabs({ event: 'change' });
// Define our own click handler for the tabs, overriding the default.
tabs.find(tab_a_selector).click(function(){
var state = {};
// Get the id of this tab widget.
id = $(this).closest( '.tabs' ).attr( 'id' );
// Get the index of this tab.
idx = $(this).parent().prevAll().length;
// Set the new state
// This is done as below to remove any state from deeper levels of nested tabs.
state ['menuTabs'] = $.bbq.getState('menuTabs');
state[ id ] = idx;
$.bbq.pushState( state, 2 );
});
tabs.find(tab_a_vertical_selector).click(function(){
var state = {};
// Get the id of this tab widget.
id = $(this).closest( '.tabs' ).attr( 'id' );
// Get the index of this tab.
idx = $(this).parent().prevAll().length;
// Set the state!
state[ id ] = idx;
// 2 -> replaces old state with new state. meaning indexes of nested tabs are removed
$.bbq.pushState( state, 2 );
});
// Bind an event to window.onhashchange that, when the history state changes,
// iterates over all tab widgets, changing the current tab as necessary.
$(window).bind( 'hashchange', function(e) {
// Iterate over all tab widgets.
tabs.each(function(){
// Get the index for this tab widget from the hash, based on the
// appropriate id property. In jQuery 1.4, you should use e.getState()
// instead of $.bbq.getState(). The second, 'true' argument coerces the
// string value to a number.
var idx = $.bbq.getState( this.id, true ) || 0;
// Select the appropriate tab for this tab widget by triggering the custom
// event specified in the .tabs() init above (you could keep track of what
// tab each widget is on using .data, and only select a tab if it has
// changed).
$(this).find( tab_a_selector).eq( idx ).triggerHandler( 'change' );
$(this).find( tab_a_vertical_selector ).eq( idx ).triggerHandler( 'change' );
});
})
// Since the event is only triggered when the hash changes, we need to trigger
// the event now, to handle the hash the page may have loaded with.
$(window).trigger( 'hashchange' );
/* -- END enables Back button for nested tabs -- */
});
</script>
<div id="menuTabs" class="tabs">
<ul>
<li><a href="#menuItem0">menuItem0</a></li>
<li><a href="#menuItem1">menuItem1</a></li>
<li><a href="#menuItem2">menuItem2</a></li>
</ul>
<div id="menuItem0" class="tabs">
<ul>
<li><a href="content/menuItem0/Intro.html">Intro</a></li>
</ul>
</div>
<div id="menuItem1" class="tabs">
<ul>
<li><a href="content/menuItem1/Intro.html">Introduction</a></li>
<li><a href="content/menuItem1/Guide.html">Guide</a></li>
<li><a href="content/menuItem1/abc.html">abc</a></li>
</ul>
</div>
<!--...-->
</div>
第 3 级选项卡位于上述 html 页面中，例如 abc.html：
<script type="text/javascript">
var rNumberTabs = $("#rNumber").tabs();
rNumberTabs.tabs({ event: 'change' });
rNumberTabs.find(tab_a_selector).click(function(){
var state = {};
// Get the id of this tab widget.
id = $(this).closest( '.tabs' ).attr( 'id' );
// Get the index of this tab.
idx = $(this).parent().prevAll().length;
// Set the state!
state[ id ] = idx;
$.bbq.pushState( state );
});
tabs = tabs.add(grNumberTabs);
// If this is triggered it leads to an infinte loop,
// if not, I can't even browse to any other tab than the first
// one on he third level, eg. it automatically jumps back
// to first one.
$(window).trigger( 'hashchange' );
</script>
<div id="rNumber" class="tabs">
<ul>
<li><a href="#layout">Layout</a></li>
<li><a href="#prefix">Prefix</a></li>
</ul>
<div id="layout">
<!-- Content here -->
</div>
<div id="prefix">
<!-- Content here -->
</div>
</div>
有什么想法可以解决吗？
