关于实现ecshop商品详细页尺码颜色选择并关联显示库存

ecshop服装商城很多都十分需要一个颜色尺码的功能，其实在淘宝，凡客上都类似的功能，客户在下单时容易选择相应的颜色尺码，其实ecshop要实现这样的功能并不难，因为ecshop是开源免费的。

 

goods.dwt修改如何下：

 

<!-- {foreach from=$spec.values item=value key=key} -->

 

<a {if $key eq 0}class="cattsel"{/if} onclick="changeAtt(this,{$value.id},{$goods.goods_id})" href="javascript:;" name="{$value.id}" title="[{if $value.price gt 0}{$lang.plus}{elseif $value.price lt 0}{$lang.minus}{/if} {$value.format_price|abs}]">{$value.label}<input style="display:none" id="spec_value_{$value.id}" type="radio" name="spec_{$spec_key}" value="{$value.id}" {if $key eq 0}checked{/if} /></a>

 

<!-- {/foreach} -->

 

在显示详细信息合适的地方加

<font style=" color:#CCCCCC;">（库存：<font id="shows_number">{$goods.goods_number} {$goods.measure_unit}</font>）</font>

 

在goods.dwt加js代码:

function changeAtt(t,a,goods_id) {

t.lastChild.checked='checked';

for (var i = 0; i<t.parentNode.childNodes.length;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)

{

$('shows_number').innerHTML = result.product_number+'件';

}

else

{

$('shows_number').innerHTML = '未设置'

}

}

 

打开goods.php添加70行左右吧

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));

 

}

 

通过以上操作便可实现仿淘宝颜色尺码选择功能
