SCRIPT：

<script type="text/javascript" language="javascript">

$(function(){

  // For each .bbq widget, keep a data object containing a mapping of
  // url-to-container for caching purposes.
  $('.bbq').each(function(){
    $(this).data( 'bbq', {
      cache: {
        // If url is '' (no fragment), display this div's content.
        '': $(this).find('.bbq-default')
      }
    });
  });

  // For all links inside a .bbq widget, push the appropriate state onto the
  // history when clicked.
  $('.bbq a[href^=#]').live( 'click', function(e){
    var state = {},

      // Get the id of this .bbq widget.
      id = $(this).closest( '.bbq' ).attr( 'id' ),

      // Get the url from the link's href attribute, stripping any leading #.
      url = $(this).attr( 'href' ).replace( /^#/, '' );

    // Set the state!
    state[ id ] = url;
    $.bbq.pushState( state );

    // And finally, prevent the default link click behavior by returning false.
    return false;
  });

  // Bind an event to window.onhashchange that, when the history state changes,
  // iterates over all .bbq widgets, getting their appropriate url from the
  // current state. If that .bbq widget's url has changed, display either our
  // cached content or fetch new content to be displayed.
  $(window).bind( 'hashchange', function(e) {

    // Iterate over all .bbq widgets.
    $('.bbq').each(function(){
      var that = $(this),

        // Get the stored data for this .bbq widget.
        data = that.data( 'bbq' ),

        // Get the url for this .bbq widget from the hash, based on the
        // appropriate id property. In jQuery 1.4, you should use e.getState()
        // instead of $.bbq.getState().
        url = $.bbq.getState( that.attr( 'id' ) ) || '';

      // If the url hasn't changed, do nothing and skip to the next .bbq widget.
      if ( data.url === url ) { return; }

      // Store the url for the next time around.
      data.url = url;

      // Remove .bbq-current class from any previously "current" link(s).
      that.find( 'a.bbq-current' ).removeClass( 'bbq-current' );

      // Hide any visible ajax content.
      that.find( '.bbq-content' ).children( ':visible' ).hide();

      // Add .bbq-current class to "current" nav link(s), only if url isn't empty.
      url && that.find( 'a[href="#' + url + '"]' ).addClass( 'bbq-current' );

      if ( data.cache[ url ] ) {
        // Since the widget is already in the cache, it doesn't need to be
        // created, so instead of creating it again, let's just show it!
        data.cache[ url ].show();

      } else {
        // Show "loading" content while AJAX content loads.
        that.find( '.bbq-loading' ).show();

        // Create container for this url's content and store a reference to it in
        // the cache.
        data.cache[ url ] = $( '<div class="bbq-item"/>' )

          // Append the content container to the parent container.
          .appendTo( that.find( '.bbq-content' ) )

          // Load external content via AJAX. Note that in order to keep this
          // example streamlined, only the content in .infobox is shown. You'll
          // want to change this based on your needs.
          .load( url, function(){
            // Content loaded, hide "loading" content.
            that.find( '.bbq-loading' ).hide();
          });
      }
    });
  })

  // 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' );

});

$(function(){

  // Syntax highlighter.
  SyntaxHighlighter.highlight();

});

</script>

BODY：

<div class="bbq" id="bbq1">
  <div class="bbq-nav bbq-nav-top">
    <a href="#burger.html">Burgers</a> |
    <a href="#chicken.html">Chicken</a> |
    <a href="#kebabs.html">Kebabs</a>
  </div>

所以，这里我的问题是我保存自己的链接？我指的是点击链接后在DIV中加载的那些内容。

内容的一个例子：“JQUERY BBQ 单击上面的导航项以加载一些美味的AJAX内容！此外，一旦内容加载，您可以通过单击您可能看到的任何内联链接来进一步探索我们的美味佳肴。＆安培;一张图片“

您的旧网址存储在浏览器历史记录中。浏览器会记住您去过的所有哈希位置。

如果我去a.com 然后去a.com＃12 然后去a.com＃1394 然后我可以在浏览器中单击它然后返回到 a.com＃12然后我可以再次点击它回到a.com

我认为bbq会将所有状态信息存储在网址中。这是$ .bbq.pushState的作用让我们来看看我最近写的一些代码。

          $(function () {
            $("a[data-custom-ajax-link='true']").click(function (e) {
                var target = $(this).data('target');
                var url = $(this).attr('href');

                $.bbq.pushState({ url: url, target: target});

                e.preventDefault();
            });

当有人点击表单的网址时

 <a href="somelink.html" data-custom-ajax-link="true" data-target='#TargetId'>Link </a>

bbq.pushState事件触发。这个bbq.pushstate以提供给bbq.pushState方法的参数的形式将一个哈希附加到url上。即

  oldurl#url=somelink.html&target=#TargetID

（除了＆amp;和=＃是url编码的）

绑定到“hashchange”窗口事件以捕获这些哈希值，因为它们滚动或退回到URL的末尾（当您单击链接并更改哈希值时或者当后退按钮和哈希值更改回来时）

   $(window).bind("hashchange", function(e) {
         var url = $.bbq.getState("url");
         var $target = $($.bbq.getState("target"));
         //fire ajax here or switch tabs etc.
    });

JQuery BBQ：存储URL的位置？
