jquery - 使用 JQuery 同时折叠和展开 Accordion（演示）

Question

我被困在使用 JQuery 的展开/折叠手风琴上。

单击初始标题并展开后，如果您单击另一个标题，它将完全折叠前一个标题，然后它将展开您单击的标题。这种先折叠然后再展开第二种技术非常分散注意力，应该发生的情况是，随着标题的展开，它应该折叠最初的标题。我错过了什么？

Answer 1

.slideUp(100,function(){ if($(".accordian>li.expanded").length==0) performOpen(doOpen,targetNode); });

就在那里......你正在执行开幕作为对结束的回调......即。它在完成时触发slideUp。Youd 需要返工，以便他们并行运行。类似于以下内容：

$(".accordian>li.expanded h2").parent().removeClass('expanded')
  .end()
  .nextAll()
  .slideUp(100);

if($(".accordian>li.expanded").length==0) {
  performOpen(doOpen,targetNode);
}

这应该可以使它们大致同时开火。

另外...您不使用 jquery-ui 的手风琴小部件是否有原因？它的样式非常容易，并且具有事件处理程序，您可以将自己的东西绑定到所有这些。:-)

Answer 2

animate 的队列参数怎么样？
