html代码:
<h2>商品分类</h2> <div class="categories"> <ul class="ulout"> <li> <a href="#"><img src="picture/ulout_add_03.png" />非标设备</a> <div class="ulin"> <a href="#">橡胶塑料</a> <a href="#">橡胶制品</a> <a href="#">冶金钢材</a> <a href="#">精细化工</a> </div> </li> <li> <a href="#"><img src="picture/ulout_add_03.png" />工控仪器</a> <div class="ulin"> <a href="#">安防监控</a> <a href="#">电工电气</a> </div> </li> <li> <a href="#"><img src="picture/ulout_add_03.png" />五金工具</a> <div class="ulin"> <a href="#">钳子</a> <a href="#">夹子</a> </div> </li> </ul> </div>
css:
<style type="text/css"> .categories{ border: 1px solid #e4e4e4; text-align: left; } ul{list-style: none;} a{text-decoration: none;} ul.ulout>li>a{ font-weight: bold; padding-left: 23px; background-position: 10px 7px; } ul.ulout>li>a>img{margin-right: 6px;} ul.ulout>li .ulin a{ font-weight: normal; color: #666666; display: block; background: url(‘./picture/ulin_icon.png‘) no-repeat; padding-left: 30px; background-position: 20px 8px; } .ulin{ display: none; } </style>
js:
<script type="text/javascript"> //先默认第一个li前面的img图片为加号样式的图片,并且里面的兄弟元素ul是展开的 $("#ulout li>a").eq(0).find("img").attr("src","picture/ulout_add_03.png‘); $("#ulout li>a").eq(0).parent().find(".ulin").slideDown(600); //点击#ulout li>a时 $("#ulout li>a").click(function(){ $(this).children("img").attr("src","picture/ulout_icon.png"); $(this).parent().siblings().find("img").attr("src","picture/ulout_add_03.png‘); $(this).parent().find(".ulin").slideDown(600); $(this).parent().siblings().find(".ulin").slideUp(600); }) </script>
个人中心的侧边栏--用jq实现侧边栏点击一块出现一块其他几块隐藏并且同时改变前面的img图片
