Question

我使用JQuery坚持使用Expand / Collapse手风琴。

点击初始标题并展开后，如果您点击另一个标题，它将完全折叠前标题，然后展开您点击的标题。这种崩溃首先扩大第二种技术是非常分散注意力的，应该发生的是当标题正在扩大它应该崩溃初始标题。我错过了什么？

Answer 1

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

就在那里......你正在开场作为对收盘的回调......即。它会在slideUp完成时触发。你需要重做这个，所以他们运行我paralell。以下内容：

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

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

这应该让它们大致在同一时间点火。

另外......你有没有理由不使用jquery-ui的手风琴小工具？它很容易风格，并有事件处理程序，你可以绑定你自己的东西为所有这些。： - ）

Answer 2

animate's queue argument怎么样？

使用JQuery同时折叠和展开Accordion（演示）
