因ecshop模板二次开发的太多了，会出现大小问题。遇到商品详情页的优惠套餐价格失效问题，怎么解决？下面是解决办法，适用京东jd2013等模板。

打开js/common.js文件，找到addToCartNums(goodsId, parentId)方法函数。
整个函数改为如下代码：

function addToCartNums(goodsId, parentId)
{
var goodsIds=goodsId.substr(0,goodsId.length-1).split(‘,’);
var buynum=goodsIds.length-1;
var gid = goodsIds[0];
for(i=0;i
{
var goods = new Object();
var spec_arr = new Array();
var fittings_arr = new Array();
var number = 1;
var quick = 1;
goods.quick = quick;
goods.spec = spec_arr;
goods.goods_id = goodsIds[i];
goods.number = 1;
if(i>0){
goods.parent = (typeof(gid) == “undefined”) ? 0 : parseInt(gid);
}

if(i==buynum)
{
Ajax.call(‘flow.php?step=add_to_cart’, ‘goods=’ + goods.toJSONString(), addToCartResponse, ‘POST’, ‘JSON’);
}
else
{
Ajax.call(‘flow.php?step=add_to_cart’, ‘goods=’ + goods.toJSONString(), ”, ‘POST’, ‘JSON’);
}

}
}
