二、添加css文件 找到style.css
.catt{width:100%;height:auto;overflow:hidden;padding-bottom:5px;}
.catt a{border: #7E7E7E 1px solid; text-align: center; background-color: #fff; margin-left:5px;margin-top:6px;padding-left: 10px;padding-right: 10px;display: block; white-space: nowrap;color:#000; text-decoration:none; float:left;}
.catt a:hover {border:#ED0036 2px solid; margin: -1px; margin-left:4px;margin-top:5px;}
.catt a:focus {outline-style:none;}
.cattsel {border:#ED0036 2px solid; margin: -1px;background: url("images/test.gif") no-repeat bottom right; margin-left:4px;margin-top:5px;}
.cattsel a:hover {border: #ED0036 2px solid;margin:-1px;background: url("images/test.gif") no-repeat bottom right;}
三、添加循环文件，找到goods.dwt文件
找到：
替换为：
href="javascript:;" name="{$value.id}" title="[{if $value.price gt 0}{$lang.plus}{elseif $value.price
lt 0}{$lang.minus}{/if} {$value.format_price|abs}]">{$value.label}
id="spec_value_{$value.id}" type="radio" name="spec_{$spec_key}" value="{$value.id}" {if $key eq 0}
checked{/if} />
四、添加js文件：
function changeAtt(t,a,goods_id) {
t.lastChild.checked='checked';
for (var i = 0; i
if (t.parentNode.childNodes[i].className == 'cattsel') {
t.parentNode.childNodes[i].className = '';
}
}
t.className = "cattsel";
var formBuy = document.forms['ECS_FORMBUY'];
spec_arr = getSelectedAttributes(formBuy);
Ajax.call('goods.php?act=get_products_info', 'id=' + spec_arr+ '&goods_id=' + goods_id, shows_number,
'GET', 'JSON');
changePrice();
}
function shows_number(result)
{
if(result.product_number !=undefined)
{
document.getElementById('shows_number').innerHTML = result.product_number+'件';
}
else
{
document.getElementById('shows_number').innerHTML = '未设置'
}
}
五、添加php文件代码 打开goods.php ，大约在71行下添加一下代码
if (!empty($_REQUEST['act']) && $_REQUEST['act'] == 'get_products_info')
{
include('includes/cls_json.php');
$json = new JSON;
// $res = array('err_msg' => '', 'result' => '', 'qty' => 1);
$spce_id = $_GET['id'];
$goods_id = $_GET['goods_id'];
$row = get_products_info($goods_id,explode(",",$spce_id));
//$res = array('err_msg'=>$goods_id,'id'=>$spce_id);
die($json->encode($row));
}
