为ecshop的添加购物车，加入图片飞入效果。
首先：
在goods.dwt中查找添加购物车按钮：
为添加购物车按钮加上id：
例如：

<a id="iproduct_{$goods.goods_id}" href="javascript:{addToCart({$goods.goods_id})">
< img src="images/bnt_cat.gif" /></a>

然后：在js中加入：

<script type="text/javascript">
var Cart = {
id: 'ECS_CARTINFO',
addProduct: function(cpid, num, t) {
//添加商品
var ops = $("[id=iproduct_"+cpid+"]").parents("#goodsInfo").children(".goodsItem").find("[id=product_"+cpid+"]");
if(ops.length>0) {
var nps = ops.clone().css({"position":"absolute", "top": ops.offset().top, "left": ops.offset().left, "z-index": 999999999}).show();
nps.appendTo("body").animate({top:$("#ECS_CARTINFO").offset().top, left: $("#ECS_CARTINFO").offset().left, width: 50, height:50}, {duration: 1000,
callback: function(){}, complete: function(){nps.remove();addToCart({$goods.goods_id});} });
}
var op = $("[id=iproduct_"+cpid+"]").parents("#goodsInfo").children('.imgInfo').find("img:first");
if(op.length>0) {
var np = op.clone().css({"position":"absolute", "top": op.offset().top, "left": op.offset().left, "z-index": 999999999}).show();
np.appendTo("body").animate({top:$("#ECS_CARTINFO").offset().top, left: $("#ECS_CARTINFO").offset().left, width: 50, height:50}, {duration: 1000,
callback:function(){}, complete: function(){np.remove();addToCart({$goods.goods_id});} });
}
}
}
$(function() {
$('[id^=iproduct_{$goods.goods_id}]').click(function() {
var cpid = this.id.replace('iproduct_{$goods.goods_id}','{$goods.goods_id}');
var n=$('#number').val();
if(n!=null||n!=undefined) {
if(n<1) {n=1;}
Cart.addProduct(cpid, n, 0);
}else{
Cart.addProduct(cpid, 1, 0);
}
return false;
});
});
< /script>

修改：
修改购物车函数：
添加购物车成功后：修改购物车显示信息：
回调函数后加入change_cart_info
在js中添加函数：

//ajax添加后更新购物车的显示信息
function change_cart_info(){
$.ajax({
type: "POST",
url: "flow.php",
data: "step=ajax_update_cart",
success:function(res){
$("#ECS_CARTINFO").html(res)
}
})
}

在flow.php中添加处理函数：

if ($_REQUEST['step'] == 'ajax_update_cart'){
// echo "ok";
$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 . "'";
$row = $GLOBALS['db']->GetRow($sql);
if ($row)
{
$number = intval($row['number']);
$amount = floatval($row['amount']);
}
else
{
$number = 0;
$amount = 0;
}
$str = sprintf($GLOBALS['_LANG']['cart_info'], $number, price_format($amount, false));
exit('<a href="flow.php" title="' . $GLOBALS['_LANG']['view_cart'] . '">' . $str . '</a>');
}
