一、加入购物车的弹窗
在ECSHOP商品详情页点“加入购物车”，直接在当前页弹出一个漂亮的小窗口，效果如下图：
此方法超级简单，不需要修改php程序，也不需要在ECSHOP模板页预设隐藏层，主要是修改 JS 文件
1.首先将下面四个图片下载到你网站的 /data/images/ 下面，注意，保存图片的时候不要重命名，要用我原来的名字直接保存
div_bg.gif
div_close.gif
div_hs.gif
div_gwc.gif
2.以下修改以官方默认模板为例，打开 ECSHOP模板文件 /themes/default/goods.dwt
将
<li class="padd"> <a href="javascript:addToCart({$goods.goods_id})"><img src="images/bnt_cat.gif" /></a>
修改为
<li class="padd" style="position:relative;" id="gwc"> <a href="javascript:addToCart({$goods.goods_id})"><img src="images/bnt_cat.gif" /></a>
3.打开 /js/common.js，找到function addToCartResponse()中的
case '1' :if (confirm(result.message)) location.href = cart_url;break;case '2' :if (!confirm(result.message)) location.href = cart_url;break;case '3' :location.href = cart_url;break;
修改为
case '1' :openDiv_ecshop120(result.content);break;case '2' :openDiv_ecshop120(result.content);break;case '3' :openDiv_ecshop120(result.content);break;
在文件的最末尾增加如下两段代码
function cancel_div_ecshop120(){document.getElementById("gwc").removeChild(docEle('speDiv'));var i=0;var sel_obj= document.getElementsByTagName('select');while(sel_obj[i]){sel_obj[i].style.visibility="visible";i++;}}/* ** 点击购物后弹出提示层* 参数 cartinfo：购物车信息*/function openDiv_ecshop120(cartinfo){var _id = "speDiv";var m = "mask";if (docEle(_id)) document.removeChild(docEle(_id));if (docEle(m)) document.removeChild(docEle(m));//计算上卷元素值var scrollPos;if(typeof window.pageYOffset != 'undefined'){scrollPos = window.pageYOffset;}else if (typeof document.compatMode != 'undefined' && document.compatMode != 'BackCompat'){scrollPos = document.documentElement.scrollTop;}else if (typeof document.body != 'undefined'){scrollPos = document.body.scrollTop;}var i = 0;var sel_obj = document.getElementsByTagName('select');while (sel_obj[i]){sel_obj[i].style.visibility = "hidden";i++;}// 新激活图层var newDiv = document.createElement("div");newDiv.id = _id;newDiv.style.position = "absolute";newDiv.style.zIndex = "10000";newDiv.style.width = "289px";newDiv.style.height = "120px";newDiv.style.top = "-120px";newDiv.style.left = "1px";newDiv.style.overflow = "hidden";newDiv.style.background = "#FFF";newDiv.style.border = "0px solid #59B0FF";newDiv.style.padding = "0px";//生成层内内容newDiv.innerHTML = '<div style="text-align:center;height:120px;line-height:25px;width:289px;background:url(data/images/div_bg.gif) no-repeat 0 0;overflow:hidden;"><table width="280px" cellpading=0 cellspacing=0 align=center ><th style="height:30px;line-height:30px;text-align:right;"><a href="javascript:cancel_div_ecshop120()" ><img src="data/images/div_close.gif" style="margin:5px 10px;"></a></th><tr><td align=center ><img src="data/images/div_hs.gif" align=absmiddle> <font style="font-size:15px;font-weight:bold;">该商品已成功放入购物车</font><br>'+cartinfo +'<br><a href="javascript:cancel_div_ecshop120()"><<继续购物</a> <a href="flow.php"> <img src="data/images/div_gwc.gif" align=absmiddle></a></td></tr>';newDiv.innerHTML += '<tr><td align=center></td></tr></table></div>';document.getElementById('gwc').appendChild(newDiv);}

二、直接购买功能的实现
ecshop如果设置了购买停留在商品页面，将ecshop商品加入购物车的时候就不会直接进入购物车。这样使用购物车非常不方便。我们为了既保持该页面功能，又能进入购物车功能。所以增加了另外一个购买按扭
点购买之后。可以直接进入ecshop的购物车。这样只牵涉到修改ecshop模板，对ecshop二次开发稍微修改就可以做到。

1.goods.dwt中，添加
<a href="javascript:addToCart1({$goods.goods_id})" id="init_quick_register_complate"><img src="images/proQuikBuyBtn.jpg"></a>
2.js/common.js，添加
function addToCart1(goodsId, parentId){ 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); Ajax.call('flow.php?step=add_to_cart1', 'goods=' + goods.toJSONString(), addToCartResponse1, 'POST', 'JSON');}function addToCartResponse1(result){ if (result.error > 0) { // 如果需要缺货登记，跳转 if (result.error == 2) { if (confirm(result.message)) { location.href = 'user.php?act=add_booking&id=' + result.goods_id + '&spec=' + result.product_spec; } } // 没选规格，弹出属性选择框 else if (result.error == 6) { openSpeDiv(result.message, result.goods_id, result.parent); } else { alert(result.message); } } else { var cartInfo = document.getElementById('ECS_CARTINFO'); var cart_url = 'flow.php?step=cart'; if (cartInfo) { cartInfo.innerHTML = result.content; } location.href = cart_url; }}
3.flow.php中，添加
