jQuery BBQ：添加淡入淡出、滑动等过渡

Question

第一次在这里问问题，但我非常喜欢使用stackoverflow。

我创建了一个使用 jQuery BBQ 以 AJAX 方式加载页面的网站，并且仍然能够使用后退按钮等来跟踪历史记录......

开箱即用的 BBQ 仅使用 .hide() 和 .show() 函数加载内容。例如，我想知道如何修改它以实现渐变等无缝过渡的最佳方式。

代码如下：

$(function(){

  // Keep a mapping of url-to-container for caching purposes.
  var cache = {
    // If url is '' (no fragment), display this div's content.
    '': $('#home')
  };

  // Bind an event to window.onhashchange that, when the history state changes,
  // gets the url from the hash and displays either our cached content or fetches
  // new content to be displayed.
  $(window).bind( 'hashchange', function(e) {

    // Get the hash (fragment) as a string, with any leading # removed. Note that
    // in jQuery 1.4, you should use e.fragment instead of $.param.fragment().
    var url = $.param.fragment();

    // Remove .current class from any previously "current" link(s).
    $( 'a.current' ).removeClass( 'current' );

    // Hide any visible ajax content.
    $( '#main' ).children( ':visible' ).hide(1000);


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

    if ( cache[ url ] ) {
      // Since the element is already in the cache, it doesn't need to be
      // created, so instead of creating it again, let's just show it!
      cache[ url ].show(1000);

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

      // Create container for this url's content and store a reference to it in
      // the cache.
     //$('.page:visible').fadeout(1000);
       url  = $( '<div class="page"/>' )

        // Append the content container to the parent container.
        .appendTo( '#main' )

        // 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.
          $( '.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' );

});

如您所见，我有一个.hide(1000) 和.show(1000)，但它似乎会闪烁页面上的所有内容，甚至是不在<div id="main"> 内的元素...

任何帮助将不胜感激。很抱歉，我不能包含该示例，因为它是我和客户之间的机密。

您应该选择 jquery addClass +css 组合，但您也可以在纯 jQuery 中通过淡入淡出或动画来实现，如下所示：

//fadeOut the element
.fadeOut(1000);
.animate({opacity: 0}, 1000);

//fadeIn the element
.fadeIn(1000);
.animate({opacity: 1}, 1000);
