ecshop购物车实现弹出框效果

本文章是以ecshop原始程序及默认模板为例进行讲述，不同的模板操作上略有不同，但原理都一样。
ecshop购物车实现弹出框效果图

操作方法：
1、后台网店设置 购物车确定提示  选择为    "提示用户，点击“取消”进入购物车"
2、打开 js/common.js  104行 就是case '1'  替换之前的 if (confirm(result.message)) location.href = cart_url;为
opencartDiv(result.shop_price,result.goods_name,result.goods_thumb,result.goods_brief,result.goods_id,result.goods_price,result.goods_number
3、复制下面这段代码
复制代码
function opencartDiv(price,name,pic,goods_brief,goods_id,total,number)
{
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 = "500px";
newDiv.style.height = "270px";
newDiv.style.top = (parseInt(scrollPos + 200)) + "px";
newDiv.style.left = (parseInt(document.body.offsetWidth) - 400) / 2 + "px"; // 屏幕居中
newDiv.style.background = "#fff";
newDiv.style.border = "5px solid #37911C";
var html = '';
//生成层内内容
html = '<div style="font-size:14;background:#8cc67b;width:480px;height:40px;line-height:40px;padding:0 10px;font-size:14px; "><span style="float:left; font-weight:bold">产品购买</span><a href=\'javascript:cancel_div()\' style="float:right;padding:0 26px 0 0;background:url(themes/popocai/images/ico_closebig.gif) right center no-repeat;cursor:pointer;" >关闭</a></div><div class="cartpopDiv"><div class="toptitle"><a href="goods.php?id='+goods_id+'" class="pic"><img src='+pic+' width="100" height="100"/></a><p><font style="font-weight:bold">'+name+'</font>  <font style="color:#ff6701">'+price+'</font><br>'+goods_brief+'</p></div>';
html += '<div class="coninfo">';
html +='<table cellpadding="0" height="30"><tr><td align="center" >购物车共有<font style="color:#ff6701;"><strong>'+number+'</strong></font>种商品：合计：<font style="color:#ff6701;"><strong>'+total+'</strong></font></td></tr>';
html += '</table>';
html +='</div>';
html +="<div style='float:left;width:450px;text-align:center;padding:15px 0 0;'><a href='index.php'><img src='themes/popocai/images/goon_ico.gif'></a>  <a href='flow.php'><img src='themes/popocai/images/jsico.gif'></a></div>";
html +='</div></div>';
newDiv.innerHTML = html;
document.body.appendChild(newDiv);
// mask图层
var newMask = document.createElement("div");
newMask.id = m;
newMask.style.position = "absolute";
newMask.style.zIndex = "9999";
newMask.style.width = document.body.scrollWidth + "px";
newMask.style.height = document.body.scrollHeight + "px";
newMask.style.top = "0px";
newMask.style.left = "0px";
newMask.style.background = "#FFF";
newMask.style.filter = "alpha(opacity=30)";
newMask.style.opacity = "0.40";
document.body.appendChild(newMask);
}

到这个common.js里  大家看了会觉的这个函数很熟悉 这就是这个文件里的 我只是拿出来修改了一下 ，当然我们可以自己重新写弹出层 比如用jquery
4、打开flow.php  181行左右加入如下代码,其实就是加入购物车成功的判断里面
复制代码
$rows = $GLOBALS['db']->getRow("select goods_brief,shop_price,goods_name,goods_thumb from ".$GLOBALS['ecs']->table('goods')." where goods_id=".$goods->goods_id);
$result['shop_price'] = price_format($rows['shop_price']);
$result['goods_name'] = $rows['goods_name'];
$result['goods_thumb'] = $rows['goods_thumb'];
$result['goods_brief'] = $rows['goods_brief'];
$result['goods_id'] = $goods->goods_id;
$sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
' FROM ' . $GLOBALS['ecs']->table('cart') .
" WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
$rowss = $GLOBALS['db']->GetRow($sql);
$result['goods_price'] = price_format($rowss['amount']);
$result['goods_number'] = $rowss['number'];
复制代码
5、本实例的样式代码和图片
复制代码
/* 购物车弹出效果*/
.cartpopDiv{
width:450px;
padding:0 25px;
float:left;
}
.toptitle{
width:450px;
float:left;
padding:16px 0;
background:url(../images/cartpop_bg.gif) left bottom repeat-x;
}
.toptitle a.pic{
float:left;
width:100px;
height:100px;
overflow:hidden;
}
.toptitle p{
float:right;
width:350px;
font-size:14px;
line-height:20px;
height:58px;
overflow:hidden;
}
.coninfo{
float:left;
width:450px;
padding:4px 0 6px;
background:url(../images/cartpop_bg.gif) left bottom repeat-x;
font-size:14px;
}
.coninfo table{
float:left;
width:100%;
border:none;
color:#a00;
}
.coninfo table td.left{
width:82px;
text-align:right;
font-weight:bold;
}
.coninfo table td.left span,
.toptitle p a{color:#333}
.coninfo table td .gray{color:#999}
.coninfo table td strong{color:#f00}
.coninfo table td font{font-size:18px}

图片直接点击另存即可，建议不要修改图片名称，如果要修改，前面代码中相应的地方也要修改。
