ECSHOP商品页仿淘宝AJAX效果

用过淘宝的朋友都知道淘宝购买商品的AJAX效果（如图），此方法通过预先隐藏层让ECSHOP模板也能达到类似效果，有需要的朋友可以照着做

 

修改goods.dwt页面的购买按钮如下
<a href=“javascript:addToCart({$goods.goods_id},0,1)”><img src=“images/bnt_cat.gif” /></a>

然后把显示的层添加到这个ECSHOP商品页（goods.dwt）的底部
<div class=“cartSure” id=“cartSureBox” style=“display:none;”> 
<div class=“btn”><a href=“javascript:;” onclick=“closeTipBox();”>关闭</a></div> 
<div class=“mesgCon”> 
<h3>宝贝已成功添加到购物车！</h3> 
<div>购物车共有<span id=“ECS_GOODS_NUMBER”></span>种商品 合计：<span id=“ECS_GOODS_PRICE”></span></div><br> 
<input type=“image” src=“images/btn_pay.gif” />

</div> 
</div>

然后打开js/common.js文件，修改 addToCart函数为
function addToCart(goodsId, parentId,is_ajax) 
{ 
var goods = new Object(); 
var spec_arr = new Array(); 
var fittings_arr = new Array(); 
var number = 1; 
var formBuy = document.forms['ECS_FORMBUY']; 
var quick = 0; 
// 检查是否有商品规格 
if (formBuy) 
{ 
spec_arr = getSelectedAttributes(formBuy);

if (formBuy.elements['number']) 
{ 
number = formBuy.elements['number'].value; 
}

quick = 1; 
}

goods.quick = quick; 
goods.spec = spec_arr; 
goods.goods_id = goodsId; 
goods.number = number; 
goods.parent = (typeof(parentId) == “undefined”) ? 0 : parseInt(parentId);

if(is_ajax == 1){ 
Ajax.call(‘flow.php?step=add_to_cart’, ’goods=’ + goods.toJS**tring(), addToCartResp**e_ajax, ’POST’, ’JSON’); 
}else{ 
Ajax.call(‘flow.php?step=add_to_cart’, ’goods=’ + goods.toJS**tring(), addToCartResp**e, ’POST’, ’JSON’); 
} 
}

添加几个js函数
function addToCart(goodsId, parentId,is_ajax) 
{ 
var goods = new Object(); 
var spec_arr = new Array(); 
var fittings_arr = new Array(); 
var number = 1; 
var formBuy = document.forms['ECS_FORMBUY']; 
var quick = 0; 
// 检查是否有商品规格 
if (formBuy) 
{ 
spec_arr = getSelectedAttributes(formBuy);

if (formBuy.elements['number']) 
{ 
number = formBuy.elements['number'].value; 
}

quick = 1; 
}

goods.quick = quick; 
goods.spec = spec_arr; 
goods.goods_id = goodsId; 
goods.number = number; 
goods.parent = (typeof(parentId) == “undefined”) ? 0 : parseInt(parentId);

if(is_ajax == 1){ 
Ajax.call(‘flow.php?step=add_to_cart’, ’goods=’ + goods.toJS**tring(), addToCartResp**e_ajax, ’POST’, ’JSON’); 
}else{ 
Ajax.call(‘flow.php?step=add_to_cart’, ’goods=’ + goods.toJS**tring(), addToCartResp**e, ’POST’, ’JSON’); 
} 
}

然后打开flow.php找到如下代码
$result['confirm_type'] = !emptyempty($_CFG['cart_confirm']) ?

在其上面添加
/* 取得商品列表，计算合计 */ 
$cart_goods = get_cart_goods(); 
//$smarty->assign(‘total’, $cart_goods['total']); 
$result['goods_price'] = $cart_goods['total']['goods_price']; 
$result['goods_number'] = $cart_goods['total']['real_goods_count'];

这样就能实现，剩下的就是图片和CSS方面的东西，可以自己天马行空了
