回复讨论(解决方案)

没有人帮我嘛。。

.addClass('icon-plus-sign').removeClass('icon-minus-sign');

这是 增加样式与去除样式。jq里用show()与hide()来显示与隐藏

我给你CSS 你看看 那都是替换展开收缩的加减图标用的,icon的css都是图标。

$(function(){    $('.tree li:has(ul)').addClass('parent_li').find(' > span').attr('title', 'Collapse this branch');    $('.tree li.parent_li > span').live('click', function (e) {             var children = $(this).parent('li.parent_li').find(' > ul > li');        if (children.is(":visible")) {            children.hide('fast');            $(this).attr('title', 'Expand this branch').find(' > i').addClass('icon-plus-sign').removeClass('icon-minus-sign');        } else {            children.show('fast');            $(this).attr('title', 'Collapse this branch').find(' > i').addClass('icon-minus-sign').removeClass('icon-plus-sign');        }        e.stopPropagation();             });});  <script>$('ul li ul:not(:first) li').hide()</script>

Hi  非常感谢! 我要去学习一下这里的live 和 on 作用  ,<script>$('ul li ul li').hide()</script> 全部缩进。
