最常见的左侧分类菜单栏jQuery实现代码打开京东、淘宝等各⼤类⽹站，最常见的就是左侧分类菜单栏了，既然这么常见的功能，那么应该怎么去实现它呢，接下来，我会在js中介绍两种实现⽅式，⼀种是引⼊jQuery的实现⽅式，⼀种是不引⼊jQuery的原⽣js的实现⽅式~~先看效果：⼀、先准备资料1）如果你们是⽤jQuery来开发⽹站的，肯定先要准备呀，这个百度⼀搜就有。不⽤jQuery开发的，可以忽略此步骤2）准备⼀些图⽚，⿏标右键 > 图⽚另存为就可以保存icon_：img_：img_：⼆、准备开发HTML代码：

静态⽂件⽽已，代码⾮常简单，copy下来即可。需要注意的是，js代码嵌⼊其中，其中⽤了两个⽅法实现，原⽣js⽅法和引⼊jQuery⽅法实现。CSS代码：*{ margin:0; padding:0; list-style: none; text-decoration:none;

}/*旅游产品分类*/.product_sort{ margin:20px; width:226px; height:644px; background:#fff url(../images/img_) no-repeat left bottom; border:solid 1px #3299fd; position:relative;
