小弟愚蠢,这个功能只实现一半,实在苦恼!
小弟愚蠢,这个功能只实现一半,实在苦恼!

做了一两天了,跟这个网站的产品筛选功能类似的。
http://sports.8t8x.com/product/yumaoqiu.htm
下面的代码我只能处理URL参数里有的字段,让它不追加重复的筛选ID,但是同类的切无法让它不追加,比如
"材质分类:"这个选项里有"碳素纤维 铝合金 铝碳一体 铁合金"
我选了碳素纤维,碳素纤维的ID是1。现在再选铝合金,铝合金的URL参数不应该包含1的。可是我无法实现

------解决方案--------------------
你现在的思路是都进来后再做字符串处理,你可以在进来之前控制数据,同一类型只能选一个。
