首先 得把价格改了
还有图片
还有点击之后加入购物车的价格
你要在哪改代码呀，方便把要改的代码发出来吗，你发的那个代码我实在看不出在哪改。

不好意思，我的意思是原来的js 不变 改的是价格和名称（这些都是由smarty）遍历出来的
小弟初学者，对上面的html 半点不懂，所以求教。贴一下smarty的遍历
<?php include 'config.php';include 'smarty.php';$tpl->assign ("title", "欢迎访问我的订餐系统");$tpl->display("index.tpl");$sql="select * from menu";$query=mysql_query("$sql" );while(($row=mysql_fetch_array($query))==true){$menuarray[]=$row;}$tpl->assign("menu_array",$menuarray); /*html 遍历{?section name=list loop=$menu_array?} {?$menu_array[list].menu_name?} //菜名 {?$menu_array[list].price?} //价格 {?sectionelse?}There is no orders.{?/section?}*/ 哦，你发的这个代码我也有点看不懂，仔细看了下你上面的html代码：
当点击的时候，触发的是这个方法：thisjs.cart_add ，这个方法有两个参数传递，一个id，一个name，你把这个两个参数换成你要传递的两个值试一下。
由于thisjs.cart_add()代码不知道如何写的，我只能分析到这里了。

另外一部分代码是这样子的 不是我写的，我可看不懂 是js
