JQuery accordion side menu and jQuery accordion menu

The following is a simple accordion menu ,:

Click B to compress the C list, and click C to change the style of its own and its parent node B. Different styles are changed during suspension.

First look at the page code, nesting of the list:

<div id="menuDiv">　　<ul id="menu">　　　　<li class="parentLi">　　　　　　<span>B</span>　　　　　　<ul class="childrenUl">　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　</ul>　　　　</li>　　　　<li class="parentLi">　　　　　　<span>B</span>　　　　　　<ul class="childrenUl">　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　</ul>　　　　</li>
　　　　<li class="parentLi">　　　　　　<span>B</span>　　　　　　<ul class="childrenUl">　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　　　<li class="childrenLi"><span>C</span></li>　　　　　　</ul>　　　　</li>　　</ul></div>

Css code, mainly set the background color and the Left Border style of the sub-menu, set the floating and selected style, and start to set the sub-menu not to display (click through js settings and then display ):

#menuDiv{    width: 200px;    background-color: #029FD4;}.parentLi{    width: 100%;    line-height: 40px;    margin-top: 1px;    background: #1C73BA;    color: #fff;    cursor: pointer;    font-weight:bolder;}.parentLi span{    padding: 10px;}.parentLi:hover, .selectedParentMenu{    background: #0033CC;}.childrenUl{    background-color: #ffffff;    display: none;}.childrenLi{    width: 100%;    line-height: 30px;    font-size: .9em;    margin-top: 1px;    background: #63B8FF;    color: #000000;    padding-left: 15px;    cursor: pointer;}.childrenLi:hover, .selectedChildrenMenu{    border-left: 5px #0033CC solid;    background: #0099CC;    padding-left: 15px;}

Next, click the Event code:

　　$(".parentLi").click(function(event) {        $(this).children('.childrenUl').slideToggle();    });    $(".childrenLi").click(function(event) {        event.stopPropagation();        $(".childrenLi").removeClass('selectedChildrenMenu');        $(".parentLi").removeClass('selectedParentMenu');        $(this).parents(".parentLi").addClass('selectedParentMenu');        $(this).addClass('selectedChildrenMenu');    });

It should be noted that the list nesting will cause event bubbles, so the click event in the sub-menu should organize bubbles, event. stopPropagation (); For details, see API.
